Dan Wesson Razorback Limited 10mm update on feeding issue: I switched to a 20lb. recoil spring and did extensive polishing of the feed ramp, chamber, chamber hood. Ran 350 rounds through her with two FTF's, which was quickly fixed by a tap/ and partial rack. I think the combination of shortening the 10mm cartridge to 1.245, barrel polishing and the 20lb. recoil spring fixed the issue. The G20 with 6" KKM Precision Barrel didn't miss a beat.
