Anyone have any load data for these for a 26 inch barrel 6.5cm using h4350 / Hornady brass/fed 210m/ whats a decent velocity for these?

140 grn hybrids (berger)
- Thread starter scorpio 25
- Start date
I can easily get 2800 with them in my 260 with a 26” barrel.
I use oddball brass and I’m guessing OP is talking 6.5 CM so I’ll skip load data.

26 in. Hawk Hill, .030 off the lands with 42.1 gr H4350, avg speed 2840 using fed 210m and Hornady brass. Recently changed to Lapua brass and went to 42.6 gr.
I think I'm right at 43 or 43.1 grains of H4350 using lapua brass and Berger 140 hybrids. Depending on the time of year they're a few FPS either side of 2,800. No pressure seated .015" off the lands.
Didn't get a chance to chono them yet. Guessing 2710 ?? Running them through a LRI 24" barrel. I'm trying three different bullets , 140 Hybrids, 140 ELDM and 140 Berger LRBT. LRBT has less bearing surface than a Hybrid. I should have state the load above was with Hornady brass. I'm also trying Peterson brass. They weigh 30 grains a case more than Hornady, and have more neck tension. I might turn the necks on the Peterson's. Trying to figure best bullet and case? Might even try Lapua brass??
25" Kreiger .169 throat, 140gr hybrid .012 off the lands , 41.0 H4350, CCI450. Lapua case. 2785 FPS.
24" RPR Stock Barrel
.020 off the lands
RL-16
41.6 gr.
Starline 6.5 CM LRP
CCI BR-2
2724 fps
Shoots sub MOA all day long everywhere I can reach as long as the shooter does their part. Quickload indicates a pressure max of 56013 psi so it's semi mello. No pressure signs what so ever.
For a 26" barrel, Quickload indicates a 2823 fps muzzle velocity. Quickload is showing a similar profile with H4350 so just start up at 41.0 and work your way up. It's velocity is a little lower by at least 30 fps. I do think that 2700 fps is a good accuracy node.
It's a fantastic projectile.
