Hi all. I’m working on getting my Gk1 .25 sighted in and I am having some issues. From anyone’s experience how different should one projectile be from one to the next in terms of accuracy. I had sighted in using JSB king exacts and it was spot on! I switched to another off brand (roughly the same weight) and the difference is like 3” at ~15 yards!!! I feel like that’s a LOT. Should I expect that much difference in different ammo? Me thinks no.
