After or before Cleaning try these Sabots. Hornady XTP 240 Grain.
I shoot 90 Grains of loose Powder and Just started using Hornady XTP 240 Grain Sabots, Nice 5/8" Groups at 100yards.
Easy to load, 10 shots before cleaning and easy to clean. Use a Brush first, Then Jag wrapped with a couple patchs sprayed with Bore Solvent, 2-3 times with clean Patches, then 1 or 2 with butter and put it away.
Good Luck.
