RE: Velocity Increases With Five Grain Powder Increases
That's the trouble with this kind of info - it gets you to wondering about other stuff.
The crush ribs load easily in the Mustang. In my "Same Load / Six Different Sabot" experiment I found that regular Harvester long sabotsshot better out of the Mustang than the crush ribs. Igot a four-shot average velocity of 1667 fps with 75 grains weight T-7 FFFG and the 300 grain Gold Dot - almost the same velocity as the crush ribs with that load - with a 1 7/8" group.
