Hey folks,
First time here and pretty new to casting. I’ve been trying to get a cast load worked up for my favorite rifle. It’s an AR pattern in .338 Razorback from Ron Williams of RMWXtreme out of Florida. Parent case is 10mm auto necked down to accept .338 rifle projectiles. Works great with 300gr SMK on 8 grains of Lil’ Gun. Problem is, those bullets cost. So I got a 315gr flat point NOE mould and tried to make it work. Not good. the flat points smash into the star chamber and at best damage the boolit but usually just fail to feed. I’ll post a pic of what that looks like, the drawing of the mould and the other mould I’m considering. Its a 273 round nose that should feed easier I think, but there remains an issue. Even though I sized down to .339 and then .338, the widest point of the bullet engages the lands and doesnt want to seat fully, and then sticks when you try and eject a loaded round. Any thoughts on how to alleviate this?
Thanks guys ✊🏻
