this is from a different post. take it for what it's worth to you. If you want Snuffers PM me...
I tried 2 different broadheads, shot both into 15 layers of cardboard (that’s all I had not 20 sorry). The penetration was fairly consistent +/- 1" or so. here are my averages from 10 - 20 - 30 yards
Equipment
Bow: Hoyt Dorado 45@28 I draw 27 ¾, with below arrow with 125 grain field points it chrono’s 198 fps.
Arrow: Easton Stalker Extreme 500's 31" with 4" feathers. 265 grains with no point.
Broadheads
Zwickey Eskilite w/5/16" bleeders 135 grain, total arrow weight is 400 grains.
Magnus Snuffers 125 grains, total arrow weight is 390 grains.
both broadheads were sharp enough to pop rubber bands/shave hair.
