Barry, Yeh, the faster it would fire the harder i would bite down, couldn't hit anything, learned to only put a couple of rnds in the mag. I have shot hundreds of coyotes from a R-44 with my shot gun, but never cared for a ar-15, for coyotes, or pigs, I have shot a few Coyotes, from a Tri-Pacer, fixed wing but used my shotgun, I would liked to have seen the 6mm setup on the fixed wing, bet that was kick ass set up.
