Does anybody have any experience casting these?? I'm curious about the mix. Should these be cast with pure lead or will wheel weights work ok?? Has anybody tried tumble lubing any hollow based wad-cutter?? I had great luck and good results casting and shooting Lee's tumble lube style 148 gr, double end wadcutter. I'm curious if I can tighten the group going the hollow based route.
The store bought HBWC I tried were swedged with pure lead and the results were remarkable but the extra $$ it just isn't worth the expense. I use 2.7grs of Bullseye in 38sp cases and bump the load up to about 3.5-4 in a 357 case. The mild load in the 38's group better than the 357's.
I'm down to less than 20lbs of pure lead and want to save it for muzzle loaders. I don't know about the rest of the regulars here but I haven't come across pure lead in quite some time for a reasonable price. Any advise on these HBWC's will certainly be appreciated, thx in advance.
