Yesterday I shot 10 rounds, average MV 2628, es 18.9, sd 6.4. Last week I shot 28 shots, average MV 2798.7, es 27.2, SD 7.2. Same rifle same load. The rife shot very good groups yesterday and seemed to shoot very good on steal last week. Xero C1 Garmin. Different location. What is the most likely explanation for the huge change in MV? I have no idea whats going on. Thanks for your input.
Might be worth starting your own post man. I almost put your experience in with the OP, and was confused for a moment until I realized you jumped on his post with your own questions.
You'll also want you add in your cartridge, cleaning regimen, and round count when you ask.
