How about the usual reloading data for the 300 PRC;

Brass manufacture
Charge weight and powder
Bullet make, weight and style (VLD, Hybrid, etc.)
Distance to lands
Overall length
Barrel length and twist
Muzzle velocity
any other data you feel is pertinent

    79.3 h1k
    Cci 200
    .020 off
    2960fps
    Best load so far
    I'm out of h1k, have a shit ton of rl26 and 225 eldm but can find no love with that combo.

    I just shot through my first 50 ADG cases on my 300 PRC. I ran a ladder to try and match my velocities with fire-formed RWS 8x68S brass. I am going to be trying:

    28" barrel @ 1-9
    ADG Brass
    73.4 gr RL 26
    Berger 230s
    BR-2 primers
    .030 off
    Expecting to average just under 2850 fps - that's where the two ladder rounds at this charge weight landed.

    I need to order a few standard neck bushings, any recommendations? Going to start with some Hornady brass.

    You might look at Whidden, i believe you can pick up their 30 cal bushing kit for $70 that includes sizes .333 to .337 or individual sizes at $16 ea. Of course there is shipping also.

    Thanks, I ended up doing that.

    Just finished load development on another 300 PRC hunting rifle...9 lbs with scope
    Specs
    Bighorn SR3
    24” Bartlein #4 carbon barrel
    1:10 twist
    Barrel work by Beanland
    Beast 4 port ti brake, very effective

    ADG brass
    CCI250 primers
    75.6 RL26 powder
    215 hybrids at .030, 3.705 OAL +/-
    2885 FPS...24” barrel
    There is plenty of room for more speed but this gives me adequate velocity at 1,200 yards to open the bullet and it’s not too fast at short range. Should be perfect for my hunting scenario.

    Forgot to mention, I’ve tested several pieces of Hornady and ADG brass for internal volume with water
    ADG...95.5
    Hornady 95.7

    In theory the same load should work in either.

    Thanks, I was just about to post that question. The Hornady brass has actually held up pretty well thru 6X

    Anybody used lead free Nosler or Hornady 180gr bullets with Retumbo? I’m working up some loads for hunting in CA.
