My results have been a bit disappointing so far, using Water's Pet Loads article as a guide. Have a like-new version of the old Single Six with adjustable sights and a lil H&R 3" stubbie. Grooves and chamber mouths seem to match up pretty well at .312"/.313" but accuracy has so far not compared with larger caliber Blackhawks, using both commercial cast and homecast boolits.
Appreciate any "pet loads" or suggestions.
Thank You, jethrow
