I bought some thin wall .38-55 to use. But it needs a little trim and blowing out out the taper. It looks a little goofy but I think they will be good plinker loads to fireform. The 200 gr. cast were running about 1200 fps from my Contender and just blowing out the taper.
We’ll have fun anyway. I did a little over (100) trimming to a bit less than 1.97”. Until I rubbed a big blister on my palm, from the knurled arbor. Good thing I’m ambidextrous, or I’d be grouchy all weekend!

They look goofy but the charge should fire form, blow out.

No, it’s Irv’s. On a 336 I think. Maybe he’ll bring to HHC. (nm)
