one thing i might mention if unfamilar with .45colt. See if you can get some of the david scovill rcbs saa bullets. Rated at 270 grain, they cast to about 283grains with wheelweights. I got a mould out of slovenia for that bullet which in addition to a keith solid, also throws a hollow and pentad hollow point.
With about 8.5 to 9 grains of unique it is a thumper. 45's are addictive. We were shooting at quemato a browning replica low wall in .45colt. Just absolutely sweet.
