The must be 40-50 Blackhawk 45's around our gun club, all with throat jobs too and they shoot really great. One is mine and shooting small groups with good handloads and cast boolits. Actually it got boring because it shoots so well so, I bought a 44 Spec flat top and now working with that one but got lucky as the throats are all equal at .431 and having a great trigger besides! Very accurate with Skeeter loads plus reduced loads of 231.
