Here' s something I' ve done that worked well. It' s a little bit off the wall but it works. I trimmed the nose of the bullet off flat. Use a file and lightly file off about 1/8 of an inch of the lead making sure it is absolutely flat. It didn' t seem to effect the accuracy at all in my old bolt action Savage. The only problem I can think of is it could possibly cause a jam in a semi rifle. It will nearly double the knock down power. I thought of this several years ago when I had a critter problem and didn' t want the critters making it back to the neighbors house. [>:] Not a single one of them took a step!! Never tried it on a turkey as we' re shotgun only around here but I bet it would work.
