Haven't seen a deer shot with one yet - my nephew will be trying Fri/Sat/Sun. Put a Mossberg rifled/ported/scoped barrel on an old Mossberg 500 and at the range it shoot VERY well w/ 12 gauge 2-3/4" Hammers. I haven't ever seen a slug make such a clean cut, large round hole like these do.

I was very happy with them.
