6PRC build opine?

[TurboTrout]

So I’m thinking of building something with more range than my 308, like the hives thoughts

6PRC, and I’d be getting into reloading for this

defiance tenacity elite action

proof carbon (twist rate? Gain twist?)

MPA competition chassis

USO FDN 25x, still deciding on rectile, like to stay MOA as all my other stuff is MOA

Worth it? Or any other suggestions for a good 1000k yrd + rifle chambering?

 

[Supersubes]

Id guess 8-900 rds barrel life max. Probably not the best cartridge to dip your toe into reloading with. What do you want to do with it? Just going for hits, or need to kill something? The 308 is easy to outperform in drop and drift. 6.5 cm, .260, 7-08, etc.

Seems my Tikka 308 is dropping off around 800-900yrds

 

[TxWelder35]

You should definitely neck down a 300 PRC instead of a 6.5 PRC. Might as well get all the speeds. And make that 6 barrels at a time

 

[Supersubes]

Thats about right. You can pump that up with better bullets, but there’s a reason the 6.5’s are so popular. They've got a fairly massive BC advantage. They recoil less as well so its like having your cake and eating it too.

 

[TurboTrout]

So 6.5prc is the top dog these days eh?

How’s it compare to 6 dasher, I remember that was the top choice not too long ago

The dasher is a small competition cartridge. Still popular. The PRC is a hunting cartridge primarily. Case capacity is almost twice that of the dasher. They’re not really comparable. You have the tenacity receiver already, and if you do I assume its a magnum bolt face?

I got nada, minus half off the USO

So dasher was my choice before I started hearing about the new PRC hotness

Ok then. The PRC has a magnum case head diameter(like a 300 wm), whereas the dasher shares the same case head as the .308. So each cartridge cant go in the same receiver. The dasher is also a wildcat, and requires brass forming. Peterson and Alpha started making brass for it someone recently, but I have no experience with it. It could also be argued that the dasher wouldn't be ideal in a Tenacity. Its too short to feed reliably from normal detachable mags. Most prefer a controlled round feed action like one of the Bighorns. Even those require special magazines. If I were you i’d pick a simpler cartridge to start with like one of the creedmoors. 6 or 6.5 mm. Like I said earlier the PRC, not really a comparable cartridge. Its a magnum version of the 6.5 Creedmoor. There is no 6mm PRC unless you have a custom barrel made buy someone who has the reamer, and you neck down the 6.5 PRC brass to make the cases.

 

[spife7980]

If you want 6mm speed just go 6 creed.

 

[Rocketmandb]

@TurboTrout do you reload?

 

[Ledzep]

I'd stray away from the 6.5 and especially the 6 PRC if you intend to shoot it a lot. Barrel life and carbon fouling will eat your lunch. 6.5 PRC is a wonderful hunting cartridge, but you simply gotta clean them every 75-150 rounds or carbon rings will wreck house. 6 PRC sounds like a recipe for blown up bullets.

6 GT, 6 Dasher, 6 BR, 6 ARC, 6 Creedmoor.... Will all do you plenty good, especially jumping from a .308, and won't burn up in 800-1200 rounds or give you carbon ring issues.

 

[Matt_3479]

6.5 like 6.5 creed, 260 rem, 260 Ai, 6.5x47 will five fly significantly more barrel life then a 6mm allowing for my practice.

The 6’a like the 6bra, 6br, 6 dasher tend to be winning the matches in multiple categories but are harder on barrel life and finicky to feed. 6 creeds, 6 gt, 6x47 lapua are much better at feeding from a mag and are lighter recoil, more enjoyable but worse barrel life

 

[TurboTrout]

I was planning to get into it for this rifle

 

[Supersubes]

I would strongly recommend you do a standard chambering, and not something that needs case forming. Get comfy with case sizing and chamber fit with standard equipment first. The Creedmoors arent sexy, but theyll stomp ass on a .308, and you dont even have to hotrod them.

Carbon fouling is not a problem inherent to the 6.5 PRC caliber, it is powder problem. If you are using RL-23 or RL-26, both popular for fast heavy bullet loads in the 6.5 PRC, then you do have to watch for carbon buildup. But if you use H1000, it's not an issue

But I agree with others above, what little you might gain in speed from a 6PRC versus a 6 Creedmoor, 6 GT etc. is too limited to be worthwhile.

 

[Ledzep]

Not exactly the same, but I had the same carbon fouling issues in a 6.5 SAUM with h1000. I think no matter how you cut it, lots of slow burning magnum powder down a 6.5mm hole.

I know guys that run 200 round 2 day matches with them and they'll often get away with it, but I've also seen them bitten by it.

 

[Shawn1492]

Skip 6prc. Go straight for 6x300PRC. It will get the speed and stoping power you want.

Basically the same as a dasher, and needs fire forming too.

So I’ve watched some of the intros to fire forming, if one can follow directions how big of a deal is it for a newbie reloader?

Just start with a 6BR and be done with it. Are you gonna fret that .1 mil wind difference at 800 with the extra 50-100fps?

Not terrible, but you still need some understanding of case fit. A standard 6BR would give up very little, and require none of that.

 

[vivdav]

I am doing a 25 creed hunting rifle. Lightweight, fast, good barrel life. I do not see any big drawbacks. Used it for a year in prs competition and accurate and a wind cheater as good as a 6 creed and 6.5 creed. Trying to figure out a good hunting bullet but the 131 ACE worked great on deer. Easy to load and as accurate as can be.

So how much would I give up do you think?

How much of a pain is fire forming?

Go to you ballistic solver. Run a 105 hybrid at 2800. Now run it at 2900. What was the difference in wind?

it seems you do not quite understand internal/external ballistics, concepts of reloading, etc. If you want to start loading I would start off as simple as possible without a bunch of added variables of things you do not understand.

 

[Supersubes]

Here’s a precision rifle blog page thats got all the variants. There’s a link for the dasher too.

Do you have a ballistics calculator, or are you familiar with JBM? Good way to make comparisons. Dont use the highest velocity numbers you can find on the internet for each cartridge though. Bc’s can be found with a quick google search usually.

For me, it’s not a pain. But it is time and effort.

The false shoulder is a more positive control on the case growth and change.

Expand the neck with a mandrel to make the whole case neck wider than the chamber neck would be.

Next size it back down until the bolt takes a fair amount of effort to cam closed on a case ensuring the the case has a good solid hold in the chamber for when it goes bang. But too much force to close is just unnecessary, shouldn’t have to hurt your hand closing.

Them load 30 grains of varget and seat a bullet progressively lower until you can close the bolt with effort but not too much effort again.

Both the false shoulder and jam methods help to make sure that the case head is solid against your bolt face ensuring that all of the growth is the case shoulder/neck folding forward to fill the chamber instead of stretching out at the bottom of it which is what leads to earlier case head separations.

Ballistics wise I use strelok pro

But yeah, I don’t know much about reloading, I don’t think I said I was a expert, but if I’m going to get into reloading, yeah it would be good to also be able to load my 308 and pump out pistol rounds, but the main reason will be for this over 1k yrd rifle. I’m pretty good with technical and machines, just looking to advice to head me in the right direction

Just do a creedmoor (doesnt matter which one) and be done. Perfect cartridge to learn on, tons of brass sources, dumb dumb accurate, good barrel life.

Are you shooting paper or steel? Formal ranges or in the countryside? Competition?

Start with a creedmore. 6.5 or 6 take your pick. 6.5 will yield quite a bit better barrel life.

 

[TX_Punisher]

6.5 creed is easy to load for with a wide variety of components that work well. Plenty for 1500yds punching paper or Ringing Steel and 6-700 on medium game.

if you want more speed the 6 creed is fun and easy to load for with less barrel life. No need to reinvent the wheel. Plenty of info out there on both to go out and have a big success level even for a beginning reloader.

ive got both and enjoy each equally.

 

[FisherT&C]

The Creedmoors would be great but it's been difficult to find 6&6.5mm bullets, things being how they are right now.
Going with a 7mm-08 might be a more economical way to go, I see 7mm bullets in stock a lot more often. With 7-08 you could neck down .308 brass. The 7-08 is less forgiving than the Creedmoor cartridges but you may just simply be able to shoot more goin the 7mm route. Just some food for thought.

Easy button from start to finish. Loading, function in standard length actions from any AI pattern magazine, components availability, etc. The standard Br is very easy to load for, but not always easy to get functioning in a mag feed gun. Both creeds will outperform the Br family in drop and drift also.

Feeding problems in BR variants, no fire forming needed with the CM options, brass is easy to come by, widely available load data, and you would be happier with the performance of a 6.5cm over the smaller 6mm options at extended distances

I also don’t disagree with the 7-08 option either if you are looking for instock projectiles. Do you have primers or powder? Neither are easy to come by. The BR variants like Varget which is not easy to find right now

 

[phantomskittles]

Just to toss another option in that I didn't see, 6xc are a decent choice as well. I would definitely steer clear of a 6prc unless you don't care about buying barrels at bulk pricing and want every possible wind advantage over the others 6mms.
