I suppose semi wadcutters would be fine, as long as I get the right hardness.
Is there just no market for wadcutters in 45? I get crap accuracy out of my model 14 Smith with anything other than swaged hollow based wadcutters. I'm getting 7-10" groups (best) at 50 yards with factory or cast, but with swaged HBWC, I get 3" 10 shot groups.
I don't even have a 45 colt yet, but I would like to have the ability to work up a good accurate load for when I do.
