The THR member must be getting sick of all my posts after this weekend, but I have one final post after my testing.
A few weeks ago I received a care package from member Dudedog with some 9mm/357sig RMR 147gr match winner and RMR 124gr MPR bullets. This was obviously a huge surprise to me in light of the current difficulty in getting certain components. Dudedog, thanks again for your generosity.
The plan was to showcase these bullets with something that is consistently accurate, which is my 357sig and CFE Pistol.
The 147gr match winner load I already shared the test results as part of my match primer post was a no-brainer since it always groups well.
The 124 gr MPR load was not a guarantee in the accuracy department, since I had to base the load on a 125gr MG bullet load, plus I used some pre-primed cases I found in storage. I probably should have used some match primers, but I decided to use the pre-primed cases.
The final results of these two loads were very good, and from an accuracy perspective, both made it to my top 10 in accuracy. I have never really looked at it this way, but I think CFE Pistol and 357sig works very well together:
