my personal opinion as an instructor here in Ak, No. Can they yes, but would I tell a new guy that, no! Reason being is most of them dont have enough knowledge in there equipment let alone know how to juice things up just to get the mech's to work 100% of the time. They might however work well on Whitetail deer, but if they start there you know what will happen, they'll try them on everything else too and I highly suspect there will be more lack of penetration issues on bigger game as some compounders are finding out the hard way up here on mid sized game. They are however deadly on turkeys from what a few friends are telling me. They are however all shooting compounds but I am sure they'd work great on the big bird as penetration isnt an issue, its not shooting through.
