The .338 GNR /200 gr. I was running 2500-2600 FPS maxed totally out. Ditto speeds for a same length barrel in 6.5x284/ 140 gr. Fastest handgun barrels I’ve used, except for .22-250 AI and .17 Remington (maxed at 3300, I was a little disappointed).
I hit the wall at 2400 with my 30GNR (might have been a little lighter bullet). I was thinking the 150 Nosler BT at 2200 fps was our hunting load.
This was my son using his .30 GNR rig with that load. He also used a handgun in 7-08 and we ran a 120 gr. around 2400 fps. We are not shooting any range though 50-75 yds. typically stalking.
Have you considered .300 AAC 110 gr. VLD projectiles? That sounds viable.

- 30 GNR -- O.A.L is 2.950" with a 150gr Nosler (nm) - Sean Harper, 2025-08-11, 10:54
- By seating the bullet longer it increases capacity - WB, 2025-08-11, 09:43
