I think they have made great improvements in ballistic tips. Hornady has recently came out with their leverolution ammo (flex tips) that were designed specifically for hunting. When purchaing balistic tip ammo, make sure it is designed for the application you intend it for. It is difficult to tell by looking, the difference between a varmint round, a match round and a hunting round; all can be ballistic tips. So you need to pay attention to the labeling on the box and do your research before choosing a bullet. Know what to expect for expansion and weight retention at different velocites and restrict your range to the bullet, cartridge combination you have. It is not just a matter of loading up a 150 grain bullet and thinking it will take every thing from 50 yards out to 500 yard be it a deer or a big bear. Know your intended target and watch your range and choose your bullet with that in mind. A bullet that will preform well at 100 yards may not do so well at 400 yards, or the other way around. A bullet that performs well out at 400 yards, may blow up at 50 yards. But instead of the 300 Winchester, it is shot in a 30-30, it will preform great. Speaking of old ballistic tips, remember the Winchester Bronze tips?
Good Luck and Good Shooting
