I use the vmax because it shoots well in my rifle & gives me the results I desire. As for shooting fmj, Kansas has no restrictions on caliber or projectile. Coyotes are vermin....vermin that cost me over $6000 in lost revenue last year from calves they killed. I owe a coyote absolutely nothing and I want them dead. If fmj's worked better I would use them. It's easy to take the moral high road when there's no toll booth.
With that said, me & the 223 laid another one down this morning at 145 yards. First saw her standing broadside at about 450 yards. Would I have taken the shot with my 22-250? Maybe. Felt like it was too far for the 223 shooting 40 grains w/ me pulling the trigger.
