Yeah , I can track when I started improving to when I started shooting 1 rifle and not messing with the load between matches. Get it tuned and shoot the same rifle and load the rest of the year and see where you are then.While I can't vouch for every one of them, Frankie has top shelf equipment....possibly too many, if that's a thing. Lol!
It can help to focus on one.
