I loved this episode! Lately I have been getting some vertical spread in my groups. I was thinking it was possibly my breathing or maybe it was just because I’m shooting factory Ammo and could be some velocity issues. My right to left spread is very consistent throughout the groups, just some vertical spread. The group sizes are usually about .4 to .6 Mia but it would be much better without the vertical like I mentioned. I have recently switched to a lighter rear bag so I’m thinking this could now also be a contributing factor. I will have to test the heavy vs light bag but I’m very excited to have this new insight. Thanks @lowlight
