300 PRC update

I finally got my RCC brass chambers in 300 PRC. Just to be clear i payed for my brass around $600 for 100 pieces. I took random 10 pieces of brass and did measurements.
As i stated before i will perform full review of RCC brass this is part 1 and part 2 will be coming after i do all testing on range.
I used Mitutoyo ball style Micrometer, and results were amazing.
Neck thickness of brass was within in 0.0005, 0.0005, 0.001, 0.0005, 0.001, 0.001, 0.0005, 0.001. 0.0005, 0.001. Better than Lapua brass that i use in my 6.5CM.

After neck thickness i weighted 10 pieces of brass. Using Lab scale FX-120i.
Brass was very close in weight 288.46gr 288.44 288.35 287.43 288,41 288.33 287,89 288.46 287.95 288.40.

Then i filled brass with H2O to measure internal case capacity and to see how consistent it was be using same scale. I think this is very important at least to me because i shoot long distance. This has big impact on Extreme Spread internal volume of brass is something that can be more than 10-20 GN that i witness in my 338Lapua brass which is consider one of best out there in my opinion.
Results came out again very consistent and close to each other.
Internal case H2O capacity: 90.98 90.91 90.81 89.90 90.80 90.91 90,82 90.99 90.98 90.95
So far I'm liking the results its very good.

Last in this part1 but not least i did perform Concentricity of brass i don't like to do this until i load ammo and do Concentricity of loaded ammo. Results were okay i can't say they were perfect because i like all my rounds to be within one thousands of and inch. I can't judge this part yet i want to fire brass at least once and load full ammo than do Concentricity on loaded ammo.
But results were okay no to write out all Measurements . Concentricity was 6 cases within in one thousands of and inch and 4 causes were 2 to 2.5 thousands of an Inch runout.

Part 2 will be:
-Load development to see how low of and extreme spread and SD i can get using RCC brass, H1000, BR-2 primers and 230gr A-Tip
-How many firings primmer pocket will hold with 80gr of H1000
-Will load case to maximum to see what kind of pressure it will hold comparing to Hornady brass which now is maxed out at 80.6Gr of H1000.

This is my test I'm no expert but i love long distance/precision shooting and as i said i payed for all this stuff with my own $$$. Just want to give something back because i learned a lot on here about 300 PRC.


What concentricity tool is that?

I highly recommend starting with a much lower powder charge and working up. I think somewhere in this thread someone did an H20 measurement of Hornady brass, and I seem to remember it being a decent bit higher.
Will do thank you

Anybody had a case separation yet? (See my previous post questioning pressure signs) Hit 4X on some Hornady last weekend, didn't notice till last night that I had 7 definitely ringed/toast, and about 15 others that are now very suspect which is close to a 30% failure rate on that lot and I'm not pushing them near what some of you guys are. Dropped the gun off this morning to have the chamber, bolt, chassis, looked over in detail. I/We would really would like to see pics from anyone of 2x, 3x fired Hndy brass bases if anyone has time. Thx.

I can get you pics on Monday. I have about 20 pieces that the primer pockets are already toast from a hot load early on in the barrel. I've backed down since and have 7x on about 80 pieces of Hornady with still a decently stout load.

I've got a bunch of ~5x fired brass. No signs of case separation. My issue was always primer pockets giving out. This is why I moved to fire-formed 8x68S
 
Thx guys for any pics. Much appreciated. Forgot to add: Nailed down two loads. 230 BHT's / .030 off / 77.4 H1K / 2860 - 21 ES / .496 @ 200 +++ 215 BHT's / .020 off / 79.6 H1K / 2898 - 17 ES / .31 vertical + 1.3 right horizontal string @ 200 (got rushed because some instructor showed up wanting to start a class and I strung em...yeah yeah...excuses are like aholes….but the bullet width vertical at 200 made my day. Best vert spread of 4 pills and 40 + combos.
 
I'm interested in what you guys are trimming at. I trim at 2.565" and I got zero growth on the last few reloadings. I know that is the Hornady spec but I've seen Hodgdon and others list 2.850" as trim length on their webapp and that is the Max case length.

I'll try and get out to the range and make some more empty brass...but dang do I hate the cold. I'll take pics of my brass for a 6x reload when I can.

I just measured new Hornady brass at 2.577 and my once fired at 2.5785 with twice fired at 2.580

2x fired. Factory Match 225 ELDm bumped .002 followed by RL26 between 72 and 74 gn pushing 212ELDx 2800-2870.

Gonna be running 212ELDX +/- 2865 with around 73.4 gn RL 26. Haven't fine tuned yet.

Anybody out there running a 300PRC with a DT SRS or Covert? I am in the UK and looking to go down this route. Many ranges over here will not allow the .338LM but will allow .30 cals. I am assuming the long action mag works fine as does the 300WM bolt assembly. I, again, assume barrel length between 22 and 26 inches.

My brother and I are. I'm running a 30 inch barrel in a srs. It's magical

For obvious reasons I may not be the best reference on this but mine were 2.577 out of the box, first round growth was .010-.013. Trimmed to 2.575 and bumped the shoulder .002 on 2x growth was .007-.009. Trimmed them back to 2.575 again for consistency and reduced bump to .001. Growth stabilized and after 4X all are 2.577 to 2.579. 2.580 is long for a 2.5874 chamber, you'd be trimming every time or risk crimping on the shoulder.

I put together a 300 prc in April but didn't draw any hunts. A friend used it for a hunt in Wolf point Montana this weekend. 26 inch Bartlein 10 twist is from Greg at SPR. We used a 200gr Barnes LRX, 80.3gr H1000 COAL 3.570 for .045" jump. 200 yard broadside hit on his left and the bullet was in the hide on his right with some shattered ribs. Lungs were liquefied.

I wrote a few weeks back that I'm doing a new 300 PRC build to go up a notch in rifle quality over my current 300 PRC.

This weekend I ordered a custom stock from Manners - I know this will take a while, but long actions are non-existent and I think finding one that meets my needs will take just as long as ordering one.

I also ordered M5 bottom metal and the same barrel I have on my current (M24, 1-9).

@Rocketmandb any reason you didn't go with a high end chassis system?

It depends on the chassis, of course, but I'm not a fan of many of them. I like simplicity combined with functionality. I get everything I need out of a more traditional stock and it is simpler to deal with and easier to clean. Additionally, I'm sold on the KMW Loggerhead cheek riser, which comes standard on Manners stocks.
 
I'd like to see Berger load 300 PRC but I won't hold my breath. The Berger 338 LM with the 300 grain OTM is a very good value. I'm seeing SDs less than 10. The Hornady ELDMs in 300 PRC are running SDs around 18 or 19.
Nope! Shot the factory hornady load out to 1950 yards and SD around 12. Maybe you are seeing higher Sds in your kit.

What twist are you guys running? I was hoping to get a load worked up that hammers with the 212 ELDX but I just haven't had time to fine tune...

So might end up using that factory 225 ELDM on elk in a week. Or a different rifle that I know is lights out.

There is no maybe. We've chrono'ed every round with a LR and have 200 down the tube, shooting 40 to 60 rounds a day. Comparing box to box, the range of SDs has been from around 18 to 21 with a global box average SD just under 20. In spite of that, the factory ammo has performed better than it's specs would suggest. Last time out we quickly got on target at 2400 then spanked that bitch steel like a red-headed stepchild.

Goinghunting, we have a 30" Bartlein 1:9 in an AX-MC. I'm staring at a box of 230 A-Tips and thinking about how good it will shoot with handloads. With the 338LM barrel in the AX, handloads typically run in the 5 to 8 SD range.
 
I went to range today with RCC brass and 230gr A-Tip to see how will brass hold pressure.
This is my load and in my rifle, please be careful because it might be different in your rifle.
RCC Brass loaded with H1000, CCI BR-2 primers and 230gr A-TiP.
Like i said in part one i will do concentricity of rounds loaded and i did, not to write out all numbers but out of 10 rounds 8 rounds where with 1 thousands of an inch and 2 rounds were runout of 1.5 thousands of and inch. In my books that's very good.

My Weather 40 F, 28.6inHg, 64% Humidity My Altitude 1030ft

76.4 GN = 2869 FPS no pressure
76.7 GN = 2876 FPS no pressure
77.0 GN = 2896 FPS no pressure
77.3 GN = 2899 FPS no pressure
77.6 GN = 2890 FPS no pressure
77.9 GN = 2913 FPS no pressure
78.2 GN = 2940 FPS no pressure NODE
78.5 GN = 2938 FPS no pressure NODE
78.8 GN = 2945 FPS no pressure NODE
80.1 GN = 2966 FPS no pressure

Now some Comparison here with Hornady Brass.
HORNADY BRASS Same powder, bullet, primers everything same but HORNADY BRASS
77.9 GN = 2859 FPS
78.2 GN = 2863 FPS
78.5 GN = 2879 FPS
78.8 GN = 2899 FPS
80.1 GN = 2919 FPS PRESSURE Signs at 80.1GN, bolt lift started being slightly
heavy/injector mark this is on Hornady Brass just to be clear.

I run out of time today because i did lots of reloading on one case to test primer pocket on RCC brass, but i did get chance at the end to load 3 rounds of 78.5GN and numbers were amazing!
2941 FPS
2941 FPS
2939 FPS
I will load 10 rounds of 78.5GN and confirm this load. Will keep you guys posted how i do with 10 rounds.

As you can see difference from RCC brass to Hornady Brass 46FPS at 78.8GN of H1000.
RCC brass holds pressure much much better than Hornady Brass. At 80.1 GN with RCC brass no pressure of signs at all. I have been loading 80GN of H1000 and shooting of my back porch same round over and over and over. At 20 firings from same case and RCC primer pocket still tight! This is impressive and that's where i stop at 20 firings.
Big question is RCC brass worth $5.65? To me YES and i will explain why. I payed with shipping for 100 rounds right around $600. Comparing that to Hornady brass is big difference but Hornady brass primers were falling out after 4th firing and i could not get Extreme spread under 15FPS. Thats due to very inconsistent internal case volume that i my self measured and it was very inconsistent. h2o test on my scale was + or - 29 GN. I did turn necks on Hornady brass annealed it did primmer pockets flash hole i did everything i could to it and it was no where close to quality to RCC brass. I love long range/precision shooting and to engage small target consistently shoot after shoot past 1400 yards you want you extreme spread to be low as you can get. Many guys that compete in long range shooting they want to be under 10 FPS extreme spread.

More to come on this testing, just to be clear again i payed with my own $$$ for all my brass and I'm doing this because i love long range shooting and giving something back here. Because i learned a lot about 300 PRC from here.

any plan to load 78.5 back to back to back etc to see when a primer finally does fail?
 
ha well...there's the answer to is the price worth it

now...do they/will they make it for the Sherman chamber in both 30cal and 7mm
They custom make it to specs, as I understand it. They can make brass for whatever cartridge you want, real or imagined.

they can.

i'd just rather Sherman pay the setup fee haha. even with the ADG and fireforming. getting 4-5 times the primer pocket life AND more consistent brass seems like a win win for all of his magnums. and it's only about 2-2.5x the cost
 
That's awesome news on the 20x with that load.

I almost convinced myself to buy some, but with the ADG announcement I need to see what that looks like first. I have 16x fired brass with a really stout load in 300 win mag with ADG brass and still going strong. If Peterson came out with some also, I would probably go that route too, as it would be less then half the cost of RCC.

But with those results you are getting so far, seems like a win though.
 
Not that anyone cares, but a Hornady case will hold 95.0 gr of RL 33. I will try an ADG case when they arrive.

Why does this matter? Cause a 6.5 creed Lapua case will hold exactly 50.0 gr of RL 26 and push a 156gr at 3000fps with that 50gr of powder with no pressure and single digit SD. If science can do that, then it can push a 250gr A tip at 3000 FPS out of a PRC. I don’t know what the ballistics are on that, but it changes things.
Holy shit!
Now I need to get some 156ers and some RL26. Is it as dirty as RL16, because that had me switch back to H4350 since there was only a marginal speed difference.

Yes they will. Talk to Jeff and send him some fired cases of your chamber he will make it happen. You won’t regret trust me, brass is best out there.

Dont take that guys bad advice. You will not get 3k with a 156 in 6.5 CM and RL26. Just like he won't get 3k with a 250gr atip in the PRC. Not sure where he is coming up with this stuff but it's bad advice all around.

It's pretty well known that around 48.5gr of RL26 is at max pending what brass you use with the 147s. 26 inch tube gets you into the 2900-2930 range. Anything above that is over max pressure for most. Maybe guys with 30 inch tubes pushing the limits into a lot of pressure get 3k. Now your adding a heavier pill and he says 50gr of RL26 powder. So yes that's bad advise in my book. I like to push the limits too, but hey, it's your rifle and I hope you get it!


Now back to the 300 PRC..

I went to range today with RCC brass and 230gr A-Tip to see how will brass hold pressure.
This is my load and in my rifle, please be careful because it might be different in your rifle.
RCC Brass loaded with H1000, CCI BR-2 primers and 230gr A-TiP.
Like i said in part one i will do concentricity of rounds loaded and i did, not to write out all numbers but out of 10 rounds 8 rounds where with 1 thousands of an inch and 2 rounds were runout of 1.5 thousands of and inch. In my books that's very good.

My Weather 40 F, 28.6inHg, 64% Humidity My Altitude 1030ft

76.4 GN = 2869 FPS no pressure
76.7 GN = 2876 FPS no pressure
77.0 GN = 2896 FPS no pressure
77.3 GN = 2899 FPS no pressure
77.6 GN = 2890 FPS no pressure
77.9 GN = 2913 FPS no pressure
78.2 GN = 2940 FPS no pressure NODE
78.5 GN = 2938 FPS no pressure NODE
78.8 GN = 2945 FPS no pressure NODE
80.1 GN = 2966 FPS no pressure

Now some Comparison here with Hornady Brass.
HORNADY BRASS Same powder, bullet, primers everything same but HORNADY BRASS
77.9 GN = 2859 FPS
78.2 GN = 2863 FPS
78.5 GN = 2879 FPS
78.8 GN = 2899 FPS
80.1 GN = 2919 FPS PRESSURE Signs at 80.1GN, bolt lift started being slightly
heavy/injector mark this is on Hornady Brass just to be clear.

I run out of time today because i did lots of reloading on one case to test primer pocket on RCC brass, but i did get chance at the end to load 3 rounds of 78.5GN and numbers were amazing!
2941 FPS
2941 FPS
2939 FPS
I will load 10 rounds of 78.5GN and confirm this load. Will keep you guys posted how i do with 10 rounds.

As you can see difference from RCC brass to Hornady Brass 46FPS at 78.8GN of H1000.
RCC brass holds pressure much much better than Hornady Brass. At 80.1 GN with RCC brass no pressure of signs at all. I have been loading 80GN of H1000 and shooting of my back porch same round over and over and over. At 20 firings from same case and RCC primer pocket still tight! This is impressive and that's where i stop at 20 firings.
Big question is RCC brass worth $5.65? To me YES and i will explain why. I payed with shipping for 100 rounds right around $600. Comparing that to Hornady brass is big difference but Hornady brass primers were falling out after 4th firing and i could not get Extreme spread under 15FPS. Thats due to very inconsistent internal case volume that i my self measured and it was very inconsistent. h2o test on my scale was + or - 29 GN. I did turn necks on Hornady brass annealed it did primmer pockets flash hole i did everything i could to it and it was no where close to quality to RCC brass. I love long range/precision shooting and to engage small target consistently shoot after shoot past 1400 yards you want you extreme spread to be low as you can get. Many guys that compete in long range shooting they want to be under 10 FPS extreme spread.

More to come on this testing, just to be clear again i payed with my own $$$ for all my brass and I'm doing this because i love long range shooting and giving something back here. Because i learned a lot about 300 PRC from here.
Rcc is doing some great things for the industry living on the past of greedy cartridge companies building brass that fails early to increase sales is bad pay more now And get a better product with Rcc and spend more time shooting vrs brass prep fire forming and developing loads Just think perhaps depending on what your shooting you brass batch will put last your barrel

My only issue with them is that I placed an order with them during the early summer, and they didn't get back to me until they ran this batch (~5 months). I chose to go another route in fire forming 8x68S - which works very well.

To RCC's credit, they did call, but it was too late for me, as I'm already invested in RWS brass.
