Magnum Wheel Man, you are right on target. I have had poor accuracy out of anything smaller than 230 grains out of a Ruger Bisley and my S&W Model 25 Classic. The rifling's rate of twist is intended for bigger bullets.
The big meplat is king most of the time, and certainly is in this caliber. 250 to 280 grain semi wad cutters going a moderate speed( 650 to 850 fps) is a proven killer.
