Load data for 300 PRC

[airassault6969]

1/2 MOA at 100 yards. 300 PRC TMAR Bolt Action Rifle. 168GR. TTSX Barnes, 82GR. Magnum powder, C.O.A.L @ 3.500 @ around 2950fps (estimate fps).

Thanks. I was playing with Quickload, as well. It looks like 82.4gr of H1000, with a 3.700 oal, and 212 ELDX would be a safe max. I was thinking to start around 78.0, just wanted another opinion.

Any luck with this load?

I fiddled with different recipes and found one with RL26 and H1000 that I like. With powder shortages going around and me wanting to shoot, I bought factory 212 ELD-X ammo and low and behold....

Was this H-1000!? What was your load of you don't mind sharing?

That was factory hornady 212 eldx believe it or not.

Didn't get to it. Decided to re-barrel with a lighter 1:10 twist tube. I plan to try that combo in the spring.

Those were factory hornady 212's eldx ammunition.

Has anyone tried loading for the 300 PRC, yet? About to order a reamer, gauges, dies and brass. I have not been able to locate any load data, yet. I plan to load a hunting round and a target round for this one.

That's a nice load. My 300PRC is on its way back after 5 month hiatus at LRI getting some upgrades done. I've got to try this one out for sure as well as the one above. I just need to score some N570 now. How temp stable is N570?

What research I've done its very good on temp stable. farest I've shoot it is 700 yards with the above load and it was very consistent. 500 yards well below 3 inch group consist.
very happy with turn powder.
I tried h1000 but n570 out shot it.
never tried rl 26

this was on a 25 inch barrel with 10 twist. 4 groove hawk hill.

74.6gr RL26,
215M's
225 ELDM.
8-shot group plugged them all into .571" with 12 fps ES and 5.4 SD.

80.0 gr H1000
cci 250's
210 Berger VLD's
Hornady Brass
.035" Jump
This load shoots .25-.3 moa at 3005 FPS in the custom rifle I bought from 8andbait in the classifieds.
I think I might be in love with it.....

On another note, I worked up from 74.0 grains and it shot roughly 1.5 moa until 80.0 gr. the difference between 79.0 and 80.0 gr was magical. Not sure why but I am happy with the end result.

Also, the same load with 210 LRAB shot around .5 moa. They were both .035" jump, but the accubond COAL was slightly longer. I can't remember what the COAL or CBTO lengths were off the top of my head.
