i just put my sharpening skills to the test this morning after i got back from a mushroom hunt! I took two old deerskins that i had laying around(use them for sinew, leatherworks, quivers, etc), and draped them over each other on a 9" thick foam backstop that i use! I then got a Snuffer tipped arrow that i used for turkey hunting this spring that was still scary sharp, and shot through the doubled up deerskins and went through the foam backstop a good 3-4" consistently for the 3 shots that i took from different angles without resharpening! An average of 14" or so from tip of broadhead to the impact point! Should work i would think, i was impressed! Shot was around 22yds  

Would stick with the snuffers myself. With a heavy arrow and sharp heads I've never had any penetration problems with a 160 snuffer. Even out of pretty light bows.

absolutely nothing wrong with the snuffers,my go to broadhead on elk.get plenty of penetration with them.i shoot 60-65 but 55 is good enough to bury one deep.ita all about placement and sharpness,get those two ingredients and you'll have elk in the freezer.
