Havent got to shoot it yet Rik.
Up to now its 20 some odd grains of VVN 110 with a 645gr Lehigh. Right around 1070 fps I think.
I'm guessing about like a 20 guage shotgun from past experience.
The last one shoved and ammo can filled with railroad spikes right off the target stand.
Good question, perhaps if some elk need managing?
