I'm using 200 grain swc bullets with a col of 1.240.. These feed fine in my Xds, but I run into issues when using them with the SR 45.. First, I thought it was a crimping issue, but even with an extra heavy crimp, I still run into feeding issues. It will fire and feed say the first 5-6 and then I'll get a feed jam. It jams on the left corner of the barrel. It catches the edge of the bullet and case. I press the bullets so .020 -.030" of the edge is exposed..
The plunk test was good. 1.260 is the max that I saw for this barrel.. 1.250 is the max for my XD-S so I take them all to 1.240...
