300 PRC update
- Thread starter DAVETOOLEY
- Start date
Awesome speed with the 230 atip. That was my plan is to get the 230 Atips at 3k plus but some were saying not possible or its WAY over pressure and get a norma instead. Even in the 29" tube I was going to spin up. I figured it wouldn't be hard to get but I'm glad you are seeing it without issue.
I'm still slinging the 215s with H1k and finally cracking into my stock of RL26 this week to get some more speed out of it.
If it didn’t have a break or can I’d agree with you. I shoot a 12lb 338 and it’s not nearly as bad as you’d think. Feels about like a 12 gauge with slugs. Without the break it’s a bit more painful, but still not unbearable. My 458 win on the other hand... fuck that gun
Several posts back, Dave Tooley used the phrase "easy button" to describe the update from 300 win mag to 300 PRC. I am hoping that also applies to the Rem 338 win mag. My current config includes a detachable 3 round mag box that measures 3.70 inches. Will I be able to make the conversion with a simple barrel change?
I load my 215 bergers to 3.700 which is 20 off the lands with the Sammi spec reamer spun up by Dave Tooley. Your COAL will be shorter with the 225s also. So looks like you should be good.
CIP mags to make it worth it. If it's a rem 700 get the KRG bravo LA stock for a cheap fix to that issue. The Cadex SH deal for the Strike nuke isn't a bad budget option either. But if your going to rebarrel and need another stock or chassis, might as well start fresh.
Please post a review when you're done! If Lapua or Peterson don't get up to speed by SS 2020 that's in the cards.
Will do. I'll probably be putting it together this weekend after I shoot on Saturday. It needs spent primers to plug the primer pockets and I don't have any!
I am having a rifle built in .300 PRC, maybe the first in The Netherlands. 28” Lothar Walther barrel, Ultimatum Deadline action, Bix'n Andy trigger, chassis to be decided. Very excited!
However, I am a bit in doubt as to what twist rate I should use. I see that the Bergara, Christensen and MRAD rifles are in 1:8, the Ruger RPR .300 PRC uses 1:9. Most people here are talking 1:9.
What should I use, assuming I will first shoot the 225 ELD-M ammunition and later handload, probably with the 225gr ELD-M, but perhaps also with the 230gr A-Tip and maybe even the 250gr A-Tip.
Hornady recommends 1:9 for the 230gr A-Tip and 1:8 for the 250gr A-Tip. Dilemma! What’s the best compromise now? I think for the 225gr ELD-M and the 230gr A-Tip I should go with 1:9. Will I then be unable to use the 250gr A-Tip?
Your advice and insights are most welcome!

I would go 1/9 and stick to the 215/230 pills. The 250 really cant get going fast enough in the PRC to be beneficial. Run some numbers and with them and see if it makes sense to you. The 9 is going to be your best bet with the 230s.
1:9 Will stabilize the 250 in most conditions, too. So even if you want to try it out, you'll be fine.
However, in most cases if you run the numbers the 230 and 250 balance out to be more or less equivalent. Almost exactly the same super-sonic range, almost exactly the same windage within 2500yd... The 230 is slightly flatter trajectory to a point (1.25-1.5 miles), but the 250 does produce more visible splash down range very reliably (not that the 230 doesn't produce good splash, though).

You need to decide if you really want to shoot that 250 pill. If the answer is yes, then you probably should go with the 1:8. Otherwise the 1:9 will handle most everything except the 230 SMKs.
Not sure you gaining much with 250gr over 230gr. 230 A-tip has high BC that within 2000 yards i think 230 will dominate.
If you want More change caliber to 338 or 300 Norma mag but they also have their disadvantages.

I bet you are right. We're still shooting factory Hornady 225 ELDMs and they are performing well considering the SD is fairly high (~20). Our rifle has a 30" Bartlein 1:9 that's not fully broke in yet (120 rounds) and is running in the 2975-3000 fps range. Today we shot it at 2400 yards and got hits and good consistency, so I'm pretty happy. I just have to get off my lazy butt and load up some of the 230 A-tips.
230 Berger, 230 SMK. CBTO jam on both fall where I’d expect between 2.8368 - 3.005 (actually almost dead center) but once there, COL is beyond 3.70. Jump at 3.70 COL: 230 Berger .013, SMK 230 .140 (yeah 1-4-0). Disappointed to lose that much seating depth flexibility. Noticing short CBTO’s at max COL with any pills?
Hi,
Not sure if it may help you or not but NIOA has a few Rugers in 300PRC....actually I am pretty sure this does not help you as I have a feeling you are looking for reamer, dies, etc type of possession
Sincerely,
Theis

Yeah, am just chasing if anyone has gotten brass and dies into Aus yet, will have the rifle sorted soon enough. Will have to stick with ADI powders as RL26 is rocking horse shit here, along with Berger projectiles
Well...I don't have an Accurate....but I prefer the MDT over the AICS....and I prefer the MDT 338LM magazine over the MDT 300WM once I got the feed lips bent right....might be a chassis/Action specific preference though...I have the MDT ACC with a Defiance Deviant Tact.
Thank you i order MDT.
Not big selection of reloading dies for 300 PRC. I hope forster and redding will release with their competition series soon.
I bought the Hornady dies with the micro adjust seater. My plan was to get this set and later get a 'better' set....but to be honest...if my groups get better due to changing dies...well I just don't see how that can happen. The limiting factor right now is ME...not the equipment nor the reloading process. I am not a candidate for testing out various primers at 1000 yards and seeing which one I like best.
Or...maybe I'm just stupid lucky to have hit on the right load with very little development with 230gr A-tips and Retumbo powder and Federal Match LRP....and what most people call....crappy ole Hornady brass.
Also...I'm out of Retumbo....HELP!!!!
Question all, I ordered the Hawkins CIP bottom metal. Inletted by LRI.
Order the accurate mag 300WM 3.85 (atleast I thought anyways)
I go to seat the magazine and it has a lot of play in the magwell. So much play to the point I can wiggle it and it disengages from mag catch and falls out.
This is on empty magazine.
Is this normal or do I have non CIP length magazine?
It fits tight on regular LA bottom metal for reference.
I uploaded some photos of gaps to show the best I could.

What should the inside dimension be?
I don’t have in front of me right now but roughly measured internal length and was like 3.6. Overall length didn’t appear to be 3.85.
I ordered from Altus Shooting. I guess I didn’t look at packaging or anything and assumed it was the right one. I may have been sent the wrong mag.
Thanks guys. I’ll call Altus tomorrow and see if they can reference my order and see if I ordered the wrong one or I was just sent the wrong one by chance.
Very nice!
what is your setup if you dont mind asking and did you try H1000 with 230 a-tip?
I can't find H1000 or RL-26 anywhere...if you know of a place...let me know
My setup is a 28" Bartlein 1-9TW at 28" with a Defiance Deviant Tactical with 20MOA rail.....and a blended APA Lil'B brake....chambered and fluted by Southern Precision Rifles.
Gently laid into an MDT ACC chassis with the adjustable grip....all currently cerakoted in FDE.
Powered by a TriggerTech Diamond.
Glass is currently borrowed....Razor GenII 4.5x27 MIL cradled by a Spurh 30MOA...in FDE.
Or were you talking about my reloading setup...heh...now that is toooo long of a list to talk about.
I got replies from Peterson and ADG earlier this year, and they both said “not this year”.
That said, it’s fire-formable from 8x68S brass.
Redding has a Custom set available, see https://www.accuratearmsandammo.com...tch-Bushing-Full-Die-Set-300-PRC-RED36776.htm
Maybe I'm just cheep, but I'd think either one of those should come with free Dick's Sporting Goods velcro socks and gloves combo.

What? Buy once...cry into your pillow because you can't eat this month. I don't see the problem.
