21 shooter Posted May 10, 2023 Share Posted May 10, 2023 That SD is impressive. I shot that load many years ago with a 124/125 jacketed bullet and it shot great in 1911’s. I’m guessing you got good accuracy with the 929? Link to comment Share on other sites More sharing options...

I'm sure somebody without shaky hands could do better. Link to comment Share on other sites More sharing options...

Cherokeewind Posted May 10, 2023 Share Posted May 10, 2023 ES number will be more relevant after checking more rounds.....my old Professor would say 4 samples are not enough to be statistically significant. Link to comment Share on other sites More sharing options...

Correct. Need at least twenty to get significance. Also learned that a low SD doesn't always mean an accurate load. GG Link to comment Share on other sites More sharing options...

I always run through two full cylinders (at least) because some chambers are "slower" than the rest. It gives me a more accurate average. Link to comment Share on other sites More sharing options...
