I am having trouble getting 147 grain blue bullets to run in the DWX. I was loading them at 1.135 oal and was having trouble with extraction after shooting a couple of hundred rounds. When I took the barrel out and but a loaded bullet (clean barrel) it did not want to fall out. I had to take oal down to 1.100 to get it to fall out consistently. I reduced the powder charge to from 3.1 of Tight Group at 1.135 Power Factor 138 to 2.9 in the 1.100. The Power Factor is 134 now but recoil is extremely hard. I believe this is due to compressing the load. What would you suggest? Different powder, bullet weight ? Any suggestions would be greatly appreciated.
