I have noticed on my 9mm pcc and 300 BO that the first couple of rings are must slower reading on my garmin. I know of first round pop but I will load a few rounds then take outside to test but realizing that’s not good if I’m getting 120 fps difference. Has anyone here experienced that. It’s something like this unfortunately I deleted the first shot thinking it was a misread but it was only 900 fps. I’ll have to do it again and save all readings.
