I finally made time to revisit the 100gr bullets I received from Dudedog. The plan was to test them with a load from a while back that seemed to performed better. I'm not sure if I just have a difficult time finding the right combination with the light bullets, or if there is something else going on.
With the test I did this weekend I actually had a couple of failure to feed. Interesting that I would experience them now for the first time, but it could be since I replaced the recoil spring after about 5k rounds.
Following are the results from the testing. You will see that the lowest charge always grouped the best, and then it deteriorated. The Xtreme 100gr deteriorated much more, so I think it is probably getting to the 1200fps limit due to its thin plating. The RMR bullet grouping also deteriorated, but not as bad as the Xtreme.

I have a few more of the Xtreme 100gr bullets from Dudedog and I think I am going to try a faster powder at a lower velocity. For now the plan is to revisit HP-38 and target a velocities between 1000fps and 1100fps.
With the test I did this weekend I actually had a couple of failure to feed. Interesting that I would experience them now for the first time, but it could be since I replaced the recoil spring after about 5k rounds.
