The petals of the 40/50 blue Shockwave sabot are designed to break away. I use 110 gr. T7 ffg and a 200 gr. Shockwave and also 105 gr. T7 ffg and a 250 gr. SST/Harvester short sabot combination in my .50 Omega. I have shot 3 shot groups at 100 yds. with each load that easily go less than an inch. I've shot the 110 gr. T7/200 Shockwave load out to 200 yds. and they are still very accurate. I am using the .25 ACP breech plug conversion from Precision Rifle also. A VERY clean bore is a must for accuracy and I swab between shots with Butch's Black Powder Bore Shine, 1 wet patch both sides and 1 dry patch both sides. This works for me!
