I have this fear that I will shoot right thru a load my gun loves and not even know it because I can't shoot for poop with it yet, and loose that load forever without a clue. Or maybe my loads so far are crap and it makes me think I can't shoot straight <dontknow> You will know ! The pattern size will decrease and it will feel right : range will be a .2 to .4 gr near max load that your gun can take without pressure signs.
