300 PRC update

[MOUNTIC]

Just shot my first few rounds for break-in. 26.25 inch Proof CF 9.4 twist. With rugged micro 30 Suppressor in the short 5 inch configuration.

More to follow.

Found that with MDT and Accurate mags in this rifle the first 3 rounds feed perfect. Then the last 2, the round on the feed lip is actually tilting the back of the case down into the mag and the bolt comes over the top of the round, not feeding. I'm sure a little mod to the mags will fix this. Figure that out later...

 

[Ledzep]

I noticed the feed lips on the Accurate mags are pretty long. Could probably handle being cut back 1/4" or so.

I noticed the feed lips on the Accurate mags are pretty long. Could probably handle being cut back 1/4" or so.

I think if I could get the round slightly higher it would feed 4 and 5 fine. The spring pressure when the mag is full doesn't let the case dip in the back and it feeds perfect. Once rounds 4 and 5 come up, no go.

Had to cut the range session short as we had to put the cows back out. They were trying to jump the fence in the pen and going to hurt themselves. Will have to shoot for groups and at distance later this week.

Just shooting a few rounds at steel while breaking it in, and it hammers that plate. Guessing this 225 will be in the 2900+ range after the barrel speeds up a bit. I'll bring the 300 Norma out this week also. Just took longer then I wanted today with breaking in the new barrel. And then the cows..

Any idea what the coal is?

Saami states 3.7

 

[verdugo60]

Is Proof doing pre-fits in the PRC already? or did you buy blank and have it chambered?

Get a TriggerTech special. I decided to splurge for one and I'm really glad i did.

Yes, they are doing savage pre-fits, not sure if they're doing AI ones yet. I have been hearing good things about the trigger tech, is the special a two stage or one?

Actually, I was thinking one thing and typed another. I meant the Diamond trigger. I have the Pro Curved version of it. It is just a single stage.

It was 20% off, and some folks even got 50% off, back for a limited time on Black Friday.

Through whom can you order the Proof 300 PRC Savage pre-fits? I didn't see it on Proof's website yet.

I'm in process of building my 300prc anyone got factory ammo available yet?

Available - yes. Hornady has Precision Hunter & Match ammo
In stock - no

Seems to pop up pretty regularly at https://www.precisionreloading.com/cart.php#!l=HN&i=82166 and https://www.precisionreloading.com/cart.php#!l=HN&i=82162

 

[WeatherbyFan]

Redding going to be making some dies any time soon? I can’t find anything on google about it.

I just received confirmation that they are making them, you can order them now

 

[C3P003]

Bergara has 300 PRC in stock, so the website states

Fierce Firearms released several 300 PRC options in their 2019 catalog:
http://fiercearms.com/2019-catalog-FIERCE-ONLINE.pdf

Eurooptics.com has listed more rifles too:

[blackta3]

Do you mean they will be available without making a custom order? I was quoted an astronomical amount a while back for custom 300 PRC dies and they said they can't do custom competition dies.

Yes he said at this moment they don't have a part # so its a special order, he said they offer the Custom Series FL,NK, and ST dies (standard style)

And yes usually pretty costly.......I can live with the Hornady dies until the Redding are mainstream.

Does Redding selling them direct? Every where I have looked and asked have turned out to be empty hopes...

 

[stereo.pete]

Looks like your outta luck with the 212s also. Need at least the 3.775 mags that take a COAL of 3.675 to run the factory ELD-X. I went to the 3.850 mags so I can make both Hornady offerings work.


3.650" on the 212 ELD-X.

3.683" on the 225 ELD-M

The action has been ordered, now I'm starting to piece together the rest of the parts. I know I'm quoting an old post, but hopefully someone here has an answer as this is my first foray into anything bigger than a short action rifle. For the bottom metal I'm looking at the accurate-mag long action bottom metal with 3.850 mags, my question is they are asking what caliber. I have the following options to choose from: 300 WM, 338LM and 300RUM. Am I correct in assuming I should be choosing the 300WM option?

Thanks in advance,

Pete

300wm mag. The 300PRC case is the diameter of the belt of the 300 Winchester.

Thank you @ubettcha !

 

[MOUNTIC]

I went with the 300wm 3.850 mags. The latest MTD mags I got from them work well. Had an issue with a few older ones but are being replaced. The latest ones work without issue. Accurate 300 win 3.850 also worked well. I had so slightly sand the inside of the lips to get it to feed a little smoother. Little tweaking pending what rifle and bottom metal is not out of the ordinary.

 

[MOUNTIC]

Just had a chance yesterday to quick zero with some 212eldx factory ammo. Was a last second deal with only a 20 minute window to get some rounds down range, so I grabbed my rifle and a box of 212s. Didn't have time to put on the Chrono, but it shot 3 rounds pretty much in the same hole. Only was able to shoot 5 rounds total. 2 sighters and then one 3 round group. I'll get some pics up later, but this Dave Tooley spun up 26 inch proof CF barrel is impressing me so far. Hope to get some more time behind it next weekend. We have about 2 feet of standing snow here where I was shooting, so it makes it hard to setup targets and all that.

 

[stereo.pete]

One last question for those of you familiar with the Accurate-Mag bottom metal. Would you recommend the single stack or the double stack variant? Both are offered in the 3.850 length magazine.

 

[Ledzep]

I'm pretty sure single stack is significantly more common for aftermarket stocks/actions. Usually easier to get single stacks to feed/work, too.

We’re you zeroing at 100 yards?

I bought the SSSF (Single Stack Single Feed?) 3.850" for a new Archimedes LA. Both are back ordered. Does anyone know if the DSSF (Double Stack Single Feed?) will work?

3.850" is considered CIP Length? (feed lips for 0.532 rims instead of super magnum rim sizes?)

 

[Jeffd]

Can anyone tell me the COAL of the factory Hornady 225 ELDM'S?
Thanks

3.683" on the 225 ELD-M. This is what my mic measured. Think published is .002 longer at 3.685

Precision reloading has 300 prc hornady brass for 47.99
Plus like eighteen hundred dollars in shipping.....

Just a heads up guys

Still haven't found the ammo yet...anyone knows who and where I can my hands on some of that and Redding dies would be much appreciated...

 

[stereo.pete]

Barrel has been ordered, it's going to be a Bartlein 9 twist Heavy Palma 29"!

 

[MOUNTIC]

Other then ammo/brass availability (for now) and mag length, would anyone even be able to have a good argument against going 300 PRC over 300 win mag? Just curious if you didn't have mag length restriction from the start if anyone would choose the WM over it?

I don't have experience reloading 300WM, but most folks I've spoke with who do, hate the belt. And it's a rebated rim.

Hope I can get my 300 PRC done before year's end. And then gotta somehow get factory ammo. Brass too.

I've been reloading 300 wm for about 12 years now. The current ADG brass offering has been my favorite. Full length Redding sizing die and the test lot of ADG brass I originally did had 14 reloads in it without any ill effects on primer pockets, etc. Velocity was within 10 fps of new virgin brass. So I haven't had many complaints. That test was with 77gr of h1000 and 200gr pills. So a decently stout load. I still have 400 new ADG brass I bought sitting here so either selling that off or getting something else in 300 wm for it. Maybe another AXMC.. The last 2 rifles I had barrels spun up for I switched to 300 prc to shoot the 212s, 215s, and some of the 225s. I'm having another custom built TL3 mag action on a CIP length manners mini chassis and I'm on the fence if I should put all my eggs in one basket on the 300prc this early on and slowly get away from the 300 win all together. Seeing I have plenty of 3.850 mags and multiple 300prcs, the COAL isn't an issue, but the brass and factory ammo / support isn't there. Hence the original question about anyone have any compelling reason to go 300 win over 300 PRC. I don't really see one other then the support, but it does seem to be gaining traction.

Since I am getting old I have learned some lessons, some the very hard way.

One of them I share with those contemplating adding a new caliber to your collection:

If you plan on actually shooting that caliber (300 PRC in this case) make sure you have either
1K pieces of good quality brass in hand or 1K rds of good quality loaded ammo before you chamber up that barrel.

Following this rule will never leave you with a rifle and no ammo to go shoot and enjoy that awesome cool guy rifle!

YMMV

I'd say 200-300 pieces of brass, but I follow a similar approach. Buy enough brass, bullets, powder, and primers of all the same lot when you buy the barrel blank, to burn the barrel out.

Haven't had a chance to shoot anything but the factory stuff. Between what Dave posted for his lighter hunting load with h4831 and the 212s and what the factory stuff measured with H1k you should have a starting point with those two powders at least.

I have some loaded up with H1k starting at 74.5 gr through 76.5 gr to start. Guessing I'll be able to get higher even but starting on the lower end. With 225s, 215s and the 212s. Will be at least another week. This thing called work gets in the way.

Hopefully Hornady will come out with something more official soon.

Good find Dave...and thanks...ordered 4 boxes here and 4 boxes at precision reloading...
Between the lower price and cheaper shipping...saved over 20 bucks...

 

[MOUNTIC]

There is a ton of brass on GunBroker also if all else fails. About the same price as others.

 

[jasent]

Shell holder is same as 300wm

 

[Ledzep]

Thanks Dave, got 200 cases, should last the barrel.... when I get the barrel

What's funny is I've got a few hundred Sinterfire 123gr .30 caliber frangibles some place sitting around. I'm really tempted to try for a prairie dog vaporizor. Was getting 3200fps from a 308 about 10 years ago, haven't touched them since.

My guess is you may reach the point of diminishing returns in the PRC but you never know.

 

[nal3470]

I know its probably already been answered but what powder are yall goin with on the 300 prc

 

[DAVETOOLEY]

Hornady loads H1000 with 225's. I use 4831SC in my hunting rifle with 212's. Anything in between those will work. Personally I lean towards a fast to middle of the road burn rate.

Hey guys,

I ordered a blank last week, I also bought some 225gr pills, actually 500. ?‍ 200 pieces of brass... decided on 1-9 twist and I am problably going to set the finished barrel at 28”.

I have a AXMC rifle so, here is the real question...Would the AI 300 WM magazine work with Hornady facyory ammo “OAL using the 225gr” pills?

Yes. The AXMC 300 win mag magazines are CIP length. I tried them yesterday.

 

[HOLLYW00D]

Any reservations chambering a Savage small shank in 300 PRC? I've read Savage had chambered some magnum barrels on the small shank, at first, but then moved those calibers to the large shank.

Also, not sure if it has been posted already, but X-Caliber has the option to select a 300 PRC chamber for their Savage small shank prefits.

***EDIT***
I should qualify further: small shank + barrel nut chambered in 300 PRC. Anything to worry about, big bada boom-wise?

Hey Dave, do you know if Hornady published a load data pdf for the 300, like they typically do for new cartridges. 6.5 PRC is up on their site already.
