First off, what the op is doing is not a "ladder test". The last time I did a "ladder test", I also used my chrono. If you watch the chrono, it will tell you where the accuracy nodes should be. Couple that with what you are seeing on paper and whala, you should be on to a good group or 2, depending on where you want to be as far as pressure and velocity. What I see here is basically the OCW method, not a true ladder. Like rost said, a ladder test is better shot at further distances: Generally at least 300-500 yards. That way you can see where the bullets start to level off and start to cluster. Also, shooting 3 shot groups isn't really telling you the whole story. Sure, a lot of us do it. I'm guilty myself, but like I said earlier, If I had a bullet that was shooting 5" groups like the op is getting, I'd chit can the idea of using said bullet. That actually happened to me the other day when I was shooting my 6WOA. The reason I told 79s I'd sell the damn thing to him
. Yeah, it didn't like 90gr gamechangers. I was so pizzed when I shot some 4" groups with what is normally a sub moa rifle shooting 85gr sierra gamekings. There are guys here that can possible help the op. Good luck with it...
