I have plenty of AA Hulls, CCI 209 primers, Remington SP wads and Green Dot powder. Published load data calls for 22.5 gr of Green Dot with the components I listed. On my PW 800+ using "O" powder bushing I can only get to 22.4 gr. Will that be OK or should I look for a different load all together. Just what is under/over grain tolerance, .1 to .2 ? I really don't what to modify my bushing. Any info would be appreciated.
