The odd thing is that the .357/1894C has a 1:16 twist rate, and shoots the heavier 180gr bullets like a champ.
I wanted a 1894 for ages, but the 1:38 twist just never had much good press for bullets in the 300gr+ range. So I bought one of the new 77/44's with a 1:20. It shoots everything from 200-300gr I've tried so far, and is very accurate with all of them.
