I recently purchased a Winchester Trapper in 45 LC at the Houston gunshow. I previously have been using 25 gr. of H-110 with a 250 XTP bullet in my Blackhawk with no pressure signs and have been told several times that the Winchester would handle anything the Ruger could. When I shot the Winchester I was thrilled with the accuracy of this load (five shots resting elbows at 100yds. gave a 4.5 inch pattern) but I noticed a bulge on one side of the case about where the sizing die stops. I have seen slight bulges on cases shot out of Ruger Blackhawks before , but never this evident and not on just one side. With no other signs of pressure( on primers or sticking of cases), is this a common lever action characteristic?
