This experience is an issue. I just received a new Hart build. It’s a 26” Hart bull barrel 1/10, Rem 700 SA, Timney trigger, on an H&S fully adjustable with an Atlas. I spent all day using different loads, going back to hard fundamentals, pulling my hair out and the dang rifle keeps jumping hard right. ( I’m right hand/right eye) Sub loads, 168s 186s with a can without a can. Behind the rifle tight and straight, angled off, prone, off hand or seated the gun is all over the place. I have two others set up the exact same way in 24” and 22” with absolutely zero problems. I kicked a mag out of each one and there was no problem point being I really really don’t think it’s me.
