How have mechanical broadheads performed for anybody on shots past 40yds., just wondering if you get pass through shots with them at extended yardages.

32 yards is as far as I can attest to, but got a complete pass-thru, and a full-width entry hole. I shoot Rocket Aerohead Miniblasters, by the way. Blood trail looked like it was poured out of a bucket.

i don't shoot beond 30 yards. don't want and take a wrisk. cuz if i make a mistake that animal could be injured for life.
i like to shoot at ranges that i think i can make a quick and humain kill

That's good fish, but you know out West your average shot is 30 to 35yds. depending on the species your hunting.
