Good evening all, I've ran into a headscratcher. I'm loading for this .218 Bee and seemed to run out of accuracy. I've gotten it to shot 2 1/2" groups at 50 yards from poor accuracy at purchase. I'm shooting cast 45 grain with gaschecks. H4895 is the powder I've settled on with CCI 400 small rifle primers. I started with 6.0 grains increased by 10%. I'm now at 9.5 grains. I've tried Lilgun, Accrate 2230, Unique, No5, Hp38, Win 748 and H380. The rifle has a Williams peep. I slugged the Bore .223 and rifling .219. The boolits are sized .223 - .225. If I'm missing some info please let me know. Any thoughts are appreciated. Thanks
