Trying to reload today for the 338 lapua using lapua brass and hornady 285 grain hpbt bullets and every 7 or 8 bullets I was noticing the c.o.a.l would be off sometimes just a few thousandths to as much as 30 thousandths. The best I can tell is the ogive on these bullets are not exact. I've reloaded for .223 and .308 and never had this problem. This isn't normal to be off this much is it?
