Got to the range yesterday with my Sig P220R. Ran a variety of ammo, both hand and factory loads, including a handful of light target loads, a 200 gr. coated SWC over 4 gr. of Bullseye. This is just barely enough powder to cycle the Sig, it has a very stiff recoil spring. But that 2-3 mags worth of bullets made a total mess of my pistol, as well as the brass, covered in soot half way down the case. I know Bullseye is on the dirty side, but this seems ridiculous. Other than changing powder, something I'll do once I've used up the Bullseye I have, would increasing the charge weight help? As this is a pretty low velocity load, IIRC it's in the 750-800 FPS range, is my bullet too hard? I'm using the 18 BRN MBC bullet, should I be using the 12 BRN for this load? Don't really want to totally abandon it, it's very soft shooting and very accurate from both my .45's. But it sure does make a mess. Any suggestions would be much appreciated, thanks.
