Did a couple of load comparisons with the Lyman Mustangin my last range session.
In one, I fired twofive-shot groups of thesame bullet and powder- a300 grainHornady HP/XTP over 100 grains volumeof Triple 7 FFG with a CCI 209 primer. O*****up was firedwith
Harvester Crush Rib sabots, and onewith
MMP HPH-24 sabots. All powder charges were weighed at 77.8 grain weight. Range was 50 yards from a bench.
You can see the results in the targetsbelow.
Velocitiesin both groupswere very close, and very consistent. The Harvester had a low velocity of 1726 fps and a high of 1754.The MMP had a low of 1709 and a high of 1752.
The Harvester group was 1 5/8 inches center to center, with four of the shots into 3/4".The MMP group was 3 1/2 inches withfour into 1 5/8".
Amazing what a little thing like a different sabot can do.
