I had one in .44Mag years ago and it shot everthing well, inc. roundballs. The conicals, 215-250ishgr., sized .429, mostly went to about the same POA (open sights when I could still see) for a given load, and I pretty much used the 6-9gr of Unique loads that I used in my revolvers back then.
All in all I wish I still had it. The $85, or so, that I got out of it in hard times didnt really do much for my 'survival'. Oh well, its all just 'stuff'.........
