6mm PRC

McNamara0851 · Sep 29, 2024

61 grains of RL26 with 90 ELD-X is yielding 0.5-0.7 moa groups at just shy of 3800 fps in a 26” 1:9 twist barrel. Never ran into pressure, but groups were opening back up beyond that. Lapua brass 210M primer. It took 100 rounds of load development to find something this barrel likes. Im going to settle on what I have for now, before I burn it out.

That bullet will be a bomb upon impact at that velocity! Would love to see some terminal necropsy photos, assuming this is a huntig rifle. I'm picking up my 6prc at the smith Wed morning, it's a 20" 7.5tw, 0.200 freebore, Bat vesper, McMillan mountain tracker LR. Plan to run nose ring 115 dtacs at 3100-3200 with rl26.

I’ve had great luck with the 90s @ 3200 out of std bolt face 6mm cartridges, they are absolute grenades. Should be pretty neat with another few pounds of energy behind them.

I have been using a 103 ELDx at around 3723fps with pretty destructive results. Fox was at 375 yards and coyote was around 250. Mine is a 6 PRC Ackley improved and I’m using Staball 6.5.

That is some psychotic damage. Did you say what twist rate? Because I'm almost certain in my 7.5twist that speed would blow those suckers up.

Definitely puts the square in the "velocity squared" term of the kinetic energy equation.

Sorry for the late response but it’s an 8 twist. No jacket failure yet. I’ve even shot 90 eldx faster just fine. The 55 noslers at 4400 blow apart though

20in 7.5tw, 58gr H1000 in adg brass, 112 Barnes at 3150fps, shoots half minute. Running it bout a grain below flat primers which is 3200fps.

Build: bat vesper, McMillan mountain tracker LR, UM DBM, ace 20" 7.5tw light palma. Running a Triji 3-18x44 tenmile, DD Wolfhunter 6mm can, and gunwerks bipod, whole setup is 10.5#, great hunting weight.
