I am having a tough time finding Federal 205M's around me. Actually have only looked at Sportsmans Warehouse, but I used to be able to get them there(I am starting to wonder why they call themselves a warehouse). I have a load for my 204 that really likes them. My question, is there a big difference in accuracy if I sub standard 205 primers? I obviously want accurate tight little groups, but I'm no bench-shooter.
