Looks like your casting and coating techniques have really improved. Does the gas check help?

Well my thoughts are that the gas check cant make it any worse and if you want to push cast lead to a decent speed then gas checks and powder coat are the easiest way to do that without having issues with the bore

I'm just having fun making bullets and giving them to friends to try in a range of rifles

Most sources on a quick search give reduction of barrel leading as the main purpose for gas checks. Also increased accuracy, but the accuracy could be due to less leading.

Yes both PC and GC are incremental improvements
@Scout has had good results with the 170 grain sized .311 from my other mold

So getting good results with lead in 30 / 303 / 8mm is pretty achievable
The next big challenge is an accurate cast 22
