I find it hard not to get accuracy from the special, especially with my hand cast bullets and book loads using Bullseye, Unique, and 2400 data from my Lyman manuals ranging from the 1950s up through the latest. The first Lyman cast bullet manual has given me some of the best loads.
Bullets: 357446, 358156, 358432, and RCBS 38-150KT and RCBS 38-200RN.
A couple, the Thompson gas check and RCBS 150 as well as the 160 grain was cutter have produced one hole groups at 25 yards from sandbags.
The 357446 out of my Ruger stainless Blackhawk, in 357 cases with 12 2400 has done 5" at 100 on a good day. (killed a deer with it also). Not hot but effective.
