Well, I don't remember the source of my info on the
melting bullets, but it was from a reliable
publication some time ago. I pushed a 200 gr lead
bullet at maybe 2150 fps and accuracy went away
seriously. I'll have to figure out some way to
capture the bullet undamaged and see what the
condition of it is.

Well, I had a nice 5 or 6 paragraph response and explanation almost ready to submit when my computer decided it needed to update and restart. So, short version- your bullets aren't "melting", they are eroding or striping or becoming so unbalanced that they fly away off the target. 100% surety they are not "melting". People are shooting paper jacketed bullets at 3000 fps and the paper isn't even scorched. I've recovered bullets shot at 2500fps plus and the lube, which has a far lower melting point than lead alloys, is still in the grooves. If you really want to know about the basics of this stuff I can re type the post I just lost. The basic principle is that it all depends on bullet fit, static and dynamic and that encompasses at least 25 variables.
Cast is not jacketed.
