The 125 tc is what I cast the most of. I have never had a problem feeding. Are you powder coating? I will never go back to lube for the boolits. I run all my powder coated boolits through a lee push through sizer. Just to make everything more consistent.
I did just get some blue Eastwood powder coat that was recommended on here earlier this week but hadn’t tried it yet. I don’t know that I need it for shooting out of an air gun... but I’m definitely going to trying it out for other things. Eventually I’d kind of like to do some .308 stuff, but that’s still a ways off. .38/.357 in both a pistol and now this air gun has been taking what little free time I have to play.
