I am a little perplexed with my garmin the last 2 days out shooting. I've only missed one shot I can remember in a couple hundred between bare muzzle, braked, and suppressed. Yesterday I was shooting my 27 Sherman mag and have done so before with no issues. It is braked. First of three rounds with a 170 Berger all picked up. Then I had a pressure test loaded with 175 sierra game changers and it didn't pick up any of the four shots. Never moved anything between any shots. Today did the same. Shot first three rounds with 170 bergers and all picked up. Then had one loaded with the 175 sierra gamechanger. Once again I moved nothing and it didn't pick it up. Shot 3 rounds after that with a braked 33 nosler and it picked all those up too. Anyone have any ideas why that would happen? The only change was the bullet but it won't pick those up. I tried a different relation from the garmin to the muzzle today vs the previous day.
