Rifling Twist Rate for a New Model SBH?

Bill Costik
I'm starting to get into reloading, and I was wondering what weight bullet a New Model SBH can handle? I realize they can handle a large variety, but I have heard that bullets over 250 grains are inaccurate in these guns. Cabelas has some Cast Performance Bullet company hardcast bullets that I would like to try, but the lowest weight they carry for .44 is 275 grains. Any ideas?

    I'm not sure where or from whom you 'heard' this bit of information, it's not important. But the Ruger NMSBH should be capable of handling any weight bullet from light to heavy if it is made for the .44 Magnum. I am not a supporter of Ruger by any means but I don't believe in slandering them stupidly. You need to call Ruger and discuss this with them and start doing some searches on the internet.

    1. Accuracy: The longer a bullet is in relation to its diameter, the more accurate it normally is. It is a rare .44 Magnum sixgun that does not shoot 300- to 320-grain bullets more accurately than it does 240- to 250 grain bullets.

    Beauty aside, the proof is in the shooting. For group testing, I mounted a trusted old Charles Daly 2-power pistol scope. As can be seen from the photos, this sixgun will shoot! All shooting was done at a range of 25 yards, and chronographed over the excellent PACT Precision chronograph at a distance of twelve feet from the muzzle. Each and every load tested gave very good performance in this revolver, with the worst group fired measuring one and three-sixteenths of an inch. That was the worst group, and would be called a great group in most any other sixgun. The best group fired measured an even half-inch for five shots at 25 yards. Every other load tested went under an inch for five shots. After evaluating the chronograph data, the largest group also was very inconsistent, and could be improved by the addition of a little more powder. Bullets tested weighed from the lightest at 165 grains up to the heaviest at 320 grains. The gun performed well with light and medium weight jacketed hollowpoints, and with light, medium, and heavy weight cast bullets.
