This has sorta left the track of my op but also brought out good points. My original quest was to find a better "why"for the small cal.,.30,8mm in my case,lack of high BC spire pointed type cast bullets or moulds. To date I've had "the tips get deformed too easy""they're too hard to get to shoot well/consistantly"and my favorite"you're an idiot if you're punching paper with TSX's". This thread has reinforced my belief that it can be done and that it will be sucessful enough for just about any caster shooter to do well.
My bullet as of now tips in at 200 grains has a .11 meplat and a calculated BC of .476 . So far hitting 1800 in any of the rifles hasn't happened due mostly ,at this point ,to lube failure. I need 1725 to get the minimum legal energy limit.
