Another Useless Cartridge Idea

[nick338]

The title says it all, but with all the ideas that are thrown out there on a regular basis, and given my inability to be content with any rifle for very long, I figured let's get some fireworks going, or at the very least be told I should pick a new hobby

I always seem to be looking for the perfect do-it all rifle, not great at any one shooting discipline, but better in most areas than your average rifle/cartridge combo. And what I mean by this is shooting to practical distances/scenarios with portable rifles, not 28-30", 20lb plus pieces of artillery.

After having all the common calibers (.224, .243, 6.5, 7, .30, .338) , I have come to the conclusion that a mid-capacity .30 caliber is the best option for me. Which is probably the reason why I am currently shooting a long action 300 WSM. However, while I am enjoying it, I feel like there is room for improvement.

Enter the 7 PRC necked up to .30 caliber. Since it was announced, I believed the 7 PRC was the perfect .284 cartridge, and best fit for the rifle I thought I wanted, but remembering my experience with a 7 SAUM at a mile with spotting misses and hearing how much better .30's anchor elk at long distance than 7's, I changed the build to a 22" 300 WSM, and began playing with 2 of my favorite bullets, the 215 Berger and 225 ELD.

Accuracy out to 600 yards has so far been stellar with the 215 Berger at 2725 fps and on a braked, 15lb rifle the recoil is very mild. I'm thinking another 100 fps or a 225 ELD at 2700 would be ideal, and given the powder charges I've been using I don't see it happening with the WSM. Of course there will be plenty of people that start screaming that a 300 Win or 300 PRC will do what you want, no problem. And they are absolutely correct, but at the expense of more powder, more recoil and less barrel life, and most likely less efficient because of a lower powder charge in a larger volume case. Or maybe I'm just splitting hairs and need to tell myself the last thing we need is another new cartridge that doesn't do anything different than cartridges that are currently available.

There's nothing ideal about shooting a mild, 215/225 .30 caliber at 1 mile but I'm not looking for ideal, and that's the point of this. The 300 WSM is as close to perfect given what's currently available but having a true long action cartridge for reliable feeding and squeezing out a little more velocity without making the next level jump to 300 Win/PRC is where I'm at with this idea. Kind of a modern day 30-06 length cartridge on steroids.

I'm confident most people will say why would any major company go through the aggravation of R&D for a cartridge that gives you such a slight increase over 1 cartridge and falls short of many others and the answer is most probably wouldn't and I'm barking up the wrong tree, yet I feel like many companies have gone down this rabbit hole before, for example Winchester, Remington and Hornady all had their hands in the pot with their own short action .30's in the early 2000's and they were all closer in performance then what I'm talking about.

Anyway, I like the idea of a .30 caliber from zero to 1 mile over any other bullet diameter and I used to be a speed guy, but I'm not anymore so squeezing every ounce of performance out of the smallest case possible is why I'm talking about this.

Ok let's hear it. I'm sure my buddy is rolling is eyes as he reads this.

 

[cas6969]

What would the case capacity be so we can compare it to the dozen other existing cartridges that are almost exactly the same?

Most of these new rounds are "might as well be"s anyway with a different rate of twist and a new name so they can ignore the SAAMI pressure specs and pump it up another 10-15K cup whether it's a good idea or not. I say have at it, but pick a cool name from the start, otherwise no one will care.

(okay I admit it, I don't know what you're talking about. I can't tell if ou want to make a full length round or a Short Mag based off the 7PRC)

 

[nick338]

Lol, I'm thinking if it's based on the 7 PRC then 79-80 grains of H20 and mid to high 60's for charge weights but no more than 70 grs.

Still working on the name

 

[Cascade Hemi]

You can actually buy 7 PRC ammunition, that makes it more ideal than a lot of other 7mm cartridges. 7PRC and 7 RemMag are almost identical. PRC and Creedmoor cartridges are viewed from a long range perspective whereas 260Rem/243Win, Winmag and, WSM are sold as hunting cartridges.

 

[cas6969]

Rick Jamison's lawyer is on the phone, he want's to know the intended cartridge's OAL.

Agreed, with the 7 PRC being slightly more efficient. Which is why I probably won't ever see this on the shelves, due to a major company not wanting to risk failure.

You can buy all Hornady PRC loadings at Cabela's, Sportsman's Warehouse, etc right now. Hornady supports the cartridges.

No I'm talking about the .30 caliber cartridge that doesn't exist yet. Trust me I was all over the 7 PRC until I decided .30 was what I really wanted.

 

[Huskydriver]

I think your misjudging the 300prc recoil and barrel life... You can sling 215s very efficiently at 2800fps in a 300prc barrel love should be as good as a 300wsm......

I've had 2 of them and ran the 220 Berger at 2850 in a 13lb rifle. Was it manageable, sure. I just feel like burning 83 grs of powder is unnecessary when I believe 68-70 will get me where I want to be. Like I said, I'm probably splitting hairs but I didn't love either one of the 300 PRC's I had.

Wtf? 83 GR of what powder? I only use 78 to push a 230 2950

I mean you do you but that sounds like a serious bullet weight to burn rate mismatch you were running....I think I was like 74ish gr with 215 at 2800ish... Recoil was very tame

 

[Cascade Hemi]

You're asking for a 300WinMag. 300PRC is about 10gr more powder capacity. 300WSM's whole claim to fame is it replicates 300WinMag in a short action.

I'll have to look at my notes but I played with N565, N568 and N570 with a 24" barrel and 83 grs is stuck in my mind for some reason.

If you wanna use less powder but maintain good load density, get some heavy brass like RWS and use less powder.

 

[wvfarrier]

I have always felt that the 300 saum was the best 30 cal cartridge

But it doesn't really with heavy bullets, as I've discovered. It's giving up at least 100 fps if not more with heavies. My current load is 63.0 grs of H4350 at 2725 and shoots lights out. It's also very close to max on that cartridge.

300NM or you can piss sitting down

 

[nick338]

This is what I'm talking about. The SAUM and the 300 RCM are so close to the WSM in performance yet they still exist. So why not add a couple of grains of powder and take the best features of all 3 (no rebated rim, milder shoulder angle), lengthen the case slightly and have an efficient .30 cal with good barrel life that doesn't beat you up?

 

[nick338]

I have one of those already.

Because I think for most of us a 300prc doesn't beat us up?

 

[Taylorbok]

I built a do anything rifle. I opted for a 284 Win-imp. 7mm will kill anything in North America and you get the same BC as a 215 Berger with less recoil. I get just a bit less velocity than a 7PRC which if it was out at the time I would have gone that route to save time and money on custom reamer and dies.

It's pretty light weight so it's easy to pack hunting but I also shot a PRS style match with it because I was having some issues with my 22 CM. I did ok but definitely wasn't ideal.

 

[Long Range 338]

Just do a 30 Creedmoor and be done.....

 

[nick338]

Because I think for most of us a 300prc doesn't beat us up?

Maybe not depending on the rifle, shooter, etc, but I would still prefer to do it with 10 grs less powder.

You're in the reloading section, you don't have to load 300 PRC balls hot. Or go have a custom reamer made for 30-7PRC. Honestly I think you're tilting at windmills.

You're right, but then end up with a shitty case fill. And you're probably right about diminishing returns, however it's never stopped the industry from being redundant before.

Sherman Mega is the capacity you're after, although I agree with many here, just use a LA cartridge and load her lightly. A 300 WM loaded to around 68 grains is very nice.

 

[nick338]

 

[nick338]

There it is. Alex Wheeler has already had the reamer made.

One advantage the SAUM has over wsm is better shoulder angles

The 300wm 94gr water capacity is with Norma brass. If you go with heavy brass and make the chamber short and tight (meaning one that doesn’t allow a virgin case to expand very much) then you’ll effectively duplicate this 30-7PRC abomination. Except no special dies, super smooth feeding from standard mags, no headaches…

 

[Bacarrat]

The other week, a friend loaded up some 215s and N570 in a 300WM and was getting 3035FPS with about 81.5gr. Got some pressure with a Proof prefit, but switched it over to a AI prefit and didn't see any pressures. To me that's pretty impressive as my 215gr loads out of my NM is running 3150 with about 10 grains more powder.

"elkaholic, this is what I have determined with H2O capacity of the RWS 300 win mag just delivered by Huntingtons.
RWS Virgin H2O volume: 92.8, 93.1, 92.6, 92.6, 92.6, 92.5
Norma resized with 0.002 bump: 93.7, 94.3, 93.9"

RWS brass is next to impossible to find.

Peterson, ADG and Hornady all make 7 PRC brass

I wasn't aware 30 degree shoulders didn't feed smoothly.

Special Die-sure it's more costly up front, but it's a one time purchase, it will match the chamber dimensions and will size all the brass I want for as long as I want to shoot it so who cares.

 

[Cascade Hemi]

WM shouldn't be giving up anything to WSM. WM max loads are 9gr to 10gr more powder than WSM. WM is half way between WSM and 300PRC. Feel free to reinvent the wheel but what you're asking for is on the market today without a special reamer.

When did I say the WM gave up anything to the WSM? It's the extra 9-10 grs of powder in the WM that I don't need.

Tons of people out there doing similar things because they're looking for something different.

7-300 PRC
7-300 WSM

6x47 Lapua

And countless others that don't drastically deviate from what's currently out there.

ADG and Peterson 300wm brass are so heavy they are pretty close to RWS. And a load in one of those, like 75grs of H1000, will do what you want.

You have no guarantee that a smaller case with less powder will produce the velocity you need. You’re making a very expensive bet. You might end up with nothing but a longer WSM.

Very true, but there's a rifle being built on it as we speak (not mine) so I will wait to see what the outcome is before I decide. I'm only at 275 rds on the WSM so no point in worrying about it now. Just thought of it as an idea once the barrel is toast on mine.

 

[UpSideDown]

You are mandating a .30cal bullet because it’s supposed to be better at seeing splash than a .284; you don’t care what velocity it gets to the target at, so long as it goes a mile and “anchors elk”, so you don’t need .300PRC; and you are raving about the joys of 300WSM, but 300WSM can’t be the answer because you already own one. So you want to spend endless time on a forum picking for ideas to then go spend thousands of dollars and likely thousands of hours of your time inventing a new cartridge that doesn’t do anything better than the suggested cartridges besides fill in an invented niche in your mind that is exactly not the do-everything application you proposed?

 

[UpSideDown]

It doesn’t matter if a cartridge is 8 grains of powder “more efficient” than an existing cartridge if your investment into inventing it wouldn’t pay off that difference in powder cost over the course of the life of 5 barrels. Add in all the time thinking, doing, and building up loads, and you’ve wasted an enormous amount of time on a single gun that - per your own comment - doesn’t sound like it’ll be used.

I suggest a degree of realism and an assessment of the value of your own time.

This is kind of my opinion as well. IMO 7mm is the perfect all around caliber, Pushing 180gr to 2850-3000 you hunt out to 1000 pretty easy, bang steel to a mile or farther and less recoil than a 30. not to mention better ballistics than a 215gr 30 cal bullet. If you want a 30 to beat a 7 you need to push the heavies just as fast other wise it doesn't take over until like a mile. Sure the splash is better and a bit better at killing but if that's your goal you should go 338 but now we've stepped away from do all rifle.

so far 7 PRC wins the all around cartridge award in my mind.

If you want to do your own wildcat go hard but to think it's going to do anything different than a 300 WSM seems unrealistic.

Apparently you weren't one of the ones talking shit about the 7 PRC that it didn't do anything the 7 Rem could do.

And there's basically very little money lost if one barrel is shot out and I'm just replacing it.

It's so amusing to listen to people cry when a new idea is not their own. It simply can't be worth a shit because they didn't think of it. Happens every time a new cartridge is released.

Sure the splash is better and a bit better at killing but if that's your goal you should go 338 but now we've stepped away from do all rifle.

so far 7 PRC wins the all around cartridge award in my mind.

If you want to do your own wildcat go hard but to think it's going to do anything different than a 300 WSM seems unrealistic.

I agree with you that the 7 PRC is the best all around cartridge. I said it from the day it was released. However I enjoy shooting .30's more for the reasons I already stated. I'm not trying to outrun the 7's. I have a 300 Norma if I want to play that game.

I don't have to wildcat it anymore because the reamer already exists, so it's as easy as a barrel change, buying a 7 PRC bushing die and having my smith open it up and away we go.

Apparently you weren't one of the ones talking shit about the 7 PRC that it didn't do anything the 7 Rem could do.

And there's basically very little money lost if one barrel is shot out and I'm just replacing it.

It's so amusing to listen to people cry when a new idea is not their own. It simply can't be worth a shit because they didn't think of it. Happens every time a new cartridge is released.

I'm all for inventing new stuff if it makes sense. I'm excited to see the next generation of cartridges when people step away from simply changing case geometry, leade, etc. and go into hybrid/alternative cases, new bullet design, etc.

Your post never struck me as inquiring into inventing a new cartridge with the intention of production. Your entire message has seemed that you want to tinker around with something with extensive overlap of use cases with existing solutions, just to play with it for a little bit before you drop it and go on to the next thing. I'm not foo-fooing your idea because it isnt' mine. I'm foo-fooing the idea because it isn't even yours. It sounds like you want to play with something like a toy and then dump it. You're asking for peoples opinions on the matter, even addressing it as being useless from the beginning, and you're not happy that we agree that it doesn't make sense?

There's 30 cartridges on the that list from post #30. I can make the argument that 25 of them don't have a huge advantage over these 5 that are also on the list, or another that's not on it.

7 Rem
284 Win
308 Win
300 Win
300 WSM

I didn't see a major company taking it on because it doesn't offer a huge advantage so yes that part is correct. I could also be wrong about that. So it was based more on desire to improve a 300 WSM type cartridge slightly with better options for brass, feeding, etc, and hopefully gain some speed since I'm already on a long action.

I never indicated at all I wanted to just treat it like a toy and dump it, however if it didn't work out and I did dump it, what do you care?

I posted it as an idea before I knew it was real thing, not sure why you have a problem with that.

The title was based on sarcasm because I knew ahead of time there would be posts like yours.

I always seem to be looking for the perfect do-it all rifle, not great at any one shooting discipline, but better in most areas than your average rifle/cartridge combo.

I guess I was mislead by this portion of your initial post. It sounds like we agree that you are taking a disadvantage to a 7PRC as a do all cartridge immediately by going to a 30 cal. I guess the title was more accurate.

I am in agreeance with @UpSideDown that you more just want to tinker with this cartridge than produce something that does anything better, which is fine and your choice but as stated there is so much overlap in this realm it doesn't make sense to me but to each their own.

When did I say the WM gave up anything to the WSM? It's the extra 9-10 grs of powder in the WM that I don't need.

Tons of people out there doing similar things because they're looking for something different.

7-300 PRC
7-300 WSM
6 Creedmoor
6x47 Lapua

And countless others that don't drastically deviate from what's currently out there.

Arguably some of your listed cartridges do in fact do something different than what was previously on the market. 30-7PRC gets you necked up Hornady brass at a fairly hefty price. That appears to be it. Apparently you just want to replicate your WSM that still has 1500 rounds of useable life left. This thread makes less and less sense as time goes on.

If it does the things that I stated better than the WSM for the reasons I stated than it's a win and I really don't need to justify it to anyone but me.

Everything has a trade off and there is no perfect cartridge, as everyone's opinion is different. If we all agreed most of these cartridges wouldn't exist in the first place.
