300 PRC update

If I had some RL26 I would gladly give you some load data....since your rifle and my rifle were chambered in most likely the exact same reamer. Mine may have been the first chamber cut with that reamer...but it was made for that 225gr ELD-M. The geometery of the 230gr A-Tip is slightly different but I didn't see much difference between the muzzle velocity between the two...but the difference in BC had me smiling....and the accuracy was wonderful....on both.
I may do <1000yds....225 ELD-M..... >1000 230gr A-Tips...
Testing 212s with RL26 28" Bartlien barrel 1:9 CCI BR primers basic case prep. Worked up tp 81 grns of 26 3200 had light ejector mark no stiff bolt. One ragged hole super low SD. Im going to do another ladder and look for a lower node in the 3100s.
Dang.. That is some HOT stuff and super fast. Guess that's what you will see when your getting close to 5grs over max.
I dont use quick load but I would be cautious with those loads. Here is the Hornady data for the PRC.
You are seeing more velocity then max loads on a 300 Norma Magnum with those loads and the 212gr pills.

Yup
Another thing weird with this rifle is it shoots factory 212s or 225 @ 3000
I feel like maybe i shouldnt have posted the speed...i assume everybody knows start waay low and work up. Never use anybody elses numbers as a target. Every rifle is different.
And every Chrono is different
Wait until you are using an older RCBS and bam!....says your 'hot load' of Retumbo is pushing a 230gr A-Tip 3560fps....you are like... WTF?....then you find out that particular Chrono is FUBAR'd and needs to go. Most of my Chronos agree...well..within 10fps anyway.
Question: Anyone else getting pressure rings at the base just above the webbing 1x fired not resized?
I wish I could answer that with 100% confidence. However, best guess is Tennon 1.503 / Face to Receiver 1.635 so 0.132 +/- with case protrusion .128 +/-. Your question likely just cost me a proper depth mic.
Either way, still just curious how many others are seeing this?
I'm north of 3040fps and my altitude is about 934 or so feet. Temp was 70F...but MUCH colder now.....go me a coyote yesterday when it was 30F and a 35+mph wind....froze my nuts off...hit him with a 300BO though.
I need to see how much a 40F temp difference makes for Retumbo and the Italian stuff....but I hate being cold...heh

I have not , to be honest I’m pretty anti-Hornady ..... I’m stuck with the brass until ADG finishes up and the Atips are the only bullet I would use from them. If they didn’t perform I was going to load the Berger’s
Anybody got any speed numbers from a shorter barrel? I’m doing a 21” 30 magnum for a hunting rifle and wondering if I can get a 215 around 2750 with a can from prc
We have a scheels where I’m at and they have been price matching powder valleys $71.06 price for me !
It's hard for me to be too down on Hornady. I've got guns like an AR-10 that none of the Hornady factory ammo can touch the Federal GMM 168s, etc. But on the 300 PRC, the Hornady factory ammo has been pretty damn good. We broke the barrel in at a mile, quickly got on target and it shot consistently. Stepped out to 2400 yards, quickly got on target and it shot consistently. Hard to beat that with factory ammo.
I just picked up a box of A-Tips and look forward to working up a load although I admit I'd rather have better brass than that Hornady putty brass.

26 inch tube here... 215 berger at 2980 with 79.26 gr of H1k without pressure even though 1gr over max. I would say you should get it without issue. Only one way to find out, right?
Yeah i just have a ton of 215s and a 10 twist rock creek and want to get full stability. Being at sea level I’m probably right on the edge.
2980 with a 26 is good. Makes me feel like I would be fine

I will be doing full review here with in a week on RCC brass. Will be receiving brass this week.
Will do full write up and review, if is anything like my friends RCC 338 brass it was better than 338 Lapua brass.

Trimming to 2.57" - Starts right above 2750 regardless of 200g or 230g pills. Didn't split a case on 3X despite pushing fairly hard (H1000 - 200s @ 3020 / 230s @ 2870). Hoping it's as simple as the brass. Can't wait for ADG to get up an running so I can find out, RCC just isn't in the budget. We already spun a 2nd barrel trying to resolve. Base to datum first one was on the long side of specs (2.21), new one is on the short side (2.197). Same brass sign on both, cut with two different reamers. Interesting Notes : 230 BHT's are better above .080 than below .020. 200 SMK's as expected .010 to .020. 230 SMK's truly need a 1:8. Obviously your results may vary.
I have read all 36 pages of posts over the last couple days, super informative. I’m curious if anymore people have tried RL33 with the heavies. I saw the two posts that have and it really interest me. I run RL 26 with 156 Berger’s in my short barreled 6.5 Creed and get 2950 and it has me thinking what if a guy stuffs 85-90 gr of RL 33 into a PRC with a 250 A tip and see if it doesn’t give us 3000 FPS. I know it’s not all about velocity but if the node is there and SD and ES is single digit we have a winner.
This is great! got an email from RCC making sure the Brass is up to my spec. I don't have a built rifle yet, but was concerned with neck OD (based on SAAMI chamber specs), it's within spec but may be a bit tight in the chamber.
The CAD/CAM engineer turned down the OD diameter some. Really good Customer service on their part.

It will hold higher pressure, primer pockets don't get lose as fast as lapua brass, his RCC 338 brass primer pockets are still good after 19 firings.
Also brass is more concentric internal volume measures exactly same within .05 measuring with H2O.
but as i said in earlier post i will be getting RCC brass for 300 PRC this coming up week and will do full test and review on RCC brass.
Also yes i paid for my brass with my $$$ which cost me around $600 for 100 pieces.
Will do review and will see if it will be worth.
