With factory 'J' boolits retailing at just over $2.00 each, it is time to look at cast boolit options. As a start, I have a 395gn Snover boolit for my 40/65 (0.409) and have paper patched 10 of these to 0.418" and seated these over 75gn of IMR4350 as a starting load for estimated 1700fps.
Would like to get a plain based cast boolit that would be powder coated to the same speed.
Interested to hear any other loads from learned gentlemen!
