Pulled lots of bullets over the years, using a hammer puller, broken several them too. Always got some deformed tips that I trimmed them up with a filet knife or side cutter and kept for Zeroing a rifle with at 25 or 50 yards. Later used them on hogs under a feeder or for shots under 100-150 yards on game, and never had a problem with penetration, accuracy or with jacket seperation in a Cup & Core bullet.
Bought my 1st Nosler Blems in 180 gr 30 cal 1st Gen BTips in a cellophane bag with a colored folded paper label stapled over the end of the bag that had been hand stamped or xeroxed with the info, for ummm $6 a bag + a little freight or even free freight one time for a bigger buy .... ran those 1st 180's in a 300WMg and never have thought they were the problem with my shooting skills on paper....and none of the critters ever said a word one way or another about them.
