I shot a cast bullet from my 375 into a snow bank and recovered a bullet. The recovered bullet diameter measured .3745". I then measured the cast bullets I was shooting -- .378" and I measured one of the jacketed bullets I had been shooting, it also measured .378".

Anomaly with the jacketed bullets -- I wonder??? These jacketed bullets were 270 grain RN bullets that where seconds (looks like Hornady to me), bought from Midway USA for about a dime on the dollar quite a while back.

I have a few other non "seconds" bullets from Hornady, Barnes, and Speer. I'll measure these tonight.

I prefer classic.
