I agree with all the recommendations to go with a gas check boolit. My reasons for not starting with one are: when I ordered the mold, gas checks often were hard to find, and when you did, the price caused heart palpitations, and; I use a Star sizer/lubricator and many moons ago when I tried a gas check boolit for a .357, the checks just fell off. (This was 50+ years ago when I was using wheel weights, which were a pretty good alloy back then, but that did not completely fill the mold. The base, then, was undersize enough that the checks couldn't hold.)
I guess that if at some time I wanted a load to stop a bear, I'll just have to use jacketed -- tolerable accuracy at shorter range.
And I'll slug the bore again to look for tight spots.
Cheers, Richard
