now I'm getting frustrated

Yeah, if you're still running the Lapua bullets jamming ain't the way to go. Factory Lapua ammo has like a .100+ jump on my tac-match reamed rifle and shoots sub MOA without blinking, and consistent.

so for the next ladder i do i should extend the range 100y and have the bullets jump about .01"? i only jammed them cause i was following the directions from the sticky on the reloading page of this forum, it said by jamming it you can safely work up to your rifle true max charge if you inspecting the cases and primer for pressure signs.
