I have not been testing any of my reloads for a while, but today I had time and I caught up with most of my backlog of testing. I tested 30 different loads today, and probably spent about 4 hours outside in the National Forest. What a beautiful day in the North West.
The testing results were ok, but I did not see any results that I could put in the WOW category. At some point the sun was in a bad sport and I started seeing missing and bad chrono readings. At this time I had one cartridge, 5 loads still to test. Tried a few things with the chrono, but just could not get any consistent readings. I made the decision to just test the last loads even though I would not have any velocity readings.
The last loads were my 357sig loads, with AA#5 using the RMR 147gr Match Winner bullet. For me it seems to be that the RMR 147gr and 357sig is a combination that lends itself to be accurate loads. The previous time I used the bullet was with CFE Pistol, with very accurate results. I had some AA#5, so I decided to try this combination also.
After shooting all 5 different loads, I realized that I did not see any super accurate load, but I also did not see any below par accuracy loads. They were all very similar. The end result basically was that I saw groupings from .59" to .98", with an average of .78". In my book that pretty good for 5 different loads. The test was done at 15 yards.
There were a few velocity readings in the 1060fps to 1080fps range, but I could not tie it to any particular load. Following are the test results (without velocities).
