JoeMKY Posted September 25, 2022 Share Posted September 25, 2022 Every time before a level ii or level iii match with the loads I’m gonna shoot that match and the gun I’m going to use just to make sure the chrono stage isn’t the death of me Link to comment Share on other sites More sharing options...
Yagi Posted September 26, 2022 Share Posted September 26, 2022 I chrono anytime I change powder lots. Load only 100 rounds, test and chrono. More often if I am using the same powder it will only deviate very very minimal. Other than that. I trust my load data I have done over the years. The only powder that made my data skewed was when using LONGSHOT Powder. I believe there was a time they had some lots that were extremely SLOW and extremely HOT.

Orlandoech Posted September 28, 2022 Share Posted September 28, 2022 Typically two to three times a year, winter, summer, some where in between. Link to comment Share on other sites More sharing options...
Yeti Posted October 4, 2022 Share Posted October 4, 2022 I always verify it after a component change. For any existing pre-tested load with no changes, I'll check it once in the Fall when the weather cools. Link to comment Share on other sites More sharing options...
RePete Posted October 4, 2022 Share Posted October 4, 2022 To be honest I don't. My PF's are 9mm - 137000, 40S&W - 155000 minor and factory for major, 45ACP - 177000 - 181000 depending on the powder I use. Link to comment Share on other sites More sharing options...
