22 vs 24 inch 6.5 Grendel Velocities.....
#34
FWIW, I was out last weekend trying to figure out what is the best hog hunting load is in my 22" Criterion Barreled Grendel and came up with the following 3 shot groups:

Bullet for all loads was a 129gr Hornady Interlock CCI standard small rifle primers and Power Pro Varmint powder.

28.3 grains yielded the following 3 velocities: 2,386 - 2,387 - 2,388

28.6 grains yielded the following 3 velocities: 2,401 - 2,389 - 2,412

28.8 grains yielded the following 3 velocities: 2,459 - 2,453 - 2,449

Velocities measured with my Labradar.

All 3 shot groups yielded 3/4" center to center groups with the final one coming in at 1/2" C to C. Cool
Speed is Fine, Accuracy is final....but accurate hits at extremely high speed is final much faster.
I don't think you understand, these boys killed my dog!
Taking the gun off safe increases the velocity by 100%
