I would like to have a 22-243, AI, 22-250 AI or the like built. My intention is a long range coyote type rifle. Not looking for a 15 pound plus bench rig, but not really a 7 pound walking rig. Questions are: Pac-Nor barrels are still pretty cheap and I have 3 others, but they have not been installed yet and are probably rusting in the corner. I know there are other makers in higher regard, but I am not looking to dump thousands on a rebarrel job. They offer several land/groove configurations. I have both 300 and 375 Ultra in progress. They steared(?) me in to 3 groove barrels on both. Not sure this is correct, but I already own them. I want 26" length, but would 28 really do anything for me? Contour will probably be a #3 fluted, maybe a #4 but I really don't care to go any heavier. Set up will be to shoot 80 VLD and 75 A-Max's exclusively. Ideally to find one good load, and make several hundred rounds and quit tinkering with powders and bullets. Any suggestions or input as to things not to do ???
