You don't have to worry about heavies, as in 250-305 grain bullets, in a .41 Magnum. I shoot many 300s in my guns and with full loads, as in 19.0 grains of H110 they stabilize just fine. One of the posters over on the S&W forum was saying one day that a Smith would not stabilize a 300 grain bullet because the twist was too slow... I posted several pics of 50 yard groups from a 6" 657 and a 5.5" Gary Reeder Custom Ruger and the holes were nice and round and about 3" groups...
One question on the 10mm when used with heavy loads in revolvers...are the any bullet pull issues since the bullet cant be roll crimped?
