Just got a loan of two "spire pointed" boolit moulds to try in my 45/70 and 45/90 Pedersoli Sharps. One (middle) is a Pedersoli 500gn and the other (sec from right) a Lyman spire point with tapered driving bands. The Lyman design only seats the last two driving bands into the case and the remaining driving bands snug into the throat.
Still have a lot of testing to do but has anyone had any success with spire point BPCR bootits?
