Ouch...that thing kicks
Hey all,
Working up a load for my new 6.5 Creedmoore (Wby. Altitude) and it seems that I bulged the shoulders out without even realizing it until I tried to chamber the rounds at the range. I figured I'd skip the Redding Type S bushing dies for this rifle, as it's a close quarters, thick woods deer gun with a 22" bbl., so I got standard RCBS dies instead (which have been more than sufficient for many of my other rifles).
Anyway, I bought a box of factory Sig Sauer 140-grain match ammo to get me on paper and to break the sum-bich in, and after that, figured I'd reload them to hone in on my pet load. Did my normal routine, brass prep, cleaned the dies, adjusting the cam-over, monitoring shoulder bump, etc. Somehow I bulged the cases at the shoulder (see pic) and don't know why? Went through the exact same routine with Starline brass and had absolutely no issues. Does Sig Sauer Brass suck or did I make a mistake?
