I apologize for bringing up a simple topic that I'm sure has been discussed before, but I'm having trouble searching for the answer, due in part to my inability to phrase the question, but here goes... I'm trying to find the range of bullet weights that a 1:20'' barrel would prefer. The gun is a Ruger New Model Superblackhawk, 7.5'' barrel with 1:20'' twist rate, .44 rem. mag. What it is lightest bullet I could shoot before over-stabilization occurs? What is the heaviest? Any input at all would be helpful, thanks.
