I can almost guarantee I am in the minority here.

I still use factory Knight .260 sabots, and have been for the past 15yrs. (The jacketed version which is actually a Speer handgun bullet). Every animal I've ever shot at is dead, with excellent performance from 20yds to 125yds. I do have a couple bullets that I have recovered...1 from a deer, and one from target shooting. Mushroomed and held together perfectly. I'll try to find them and post a pic if I have time. I'm old school I guess....its the don't fix it if it ain't broke thing.

I do plan to do some bullet testing for fun this year, and may even try some new bullets on game next season. Not for lack of performance though, can't complain about the Knights (Speers).
