I have a 10" barrel 222 and a 21" barrel 223 and both absolutely love a Bullseye load of about 4.5 gr. but I hate using a load that small. Too easy to make a mistake so I take lots of time per round. I have tried many other powders using more volume but keep having to go back to Bullseye. I know the saying "if it ain't broke, …". Not really frustrated, just whining a little.
