New scope on Knight Vision
 

put a new Powder Horn scope on my Knight Vision I like it a lot better than the scope I got with it from Sportsman's Warehouse.
Got it shooting fairly decent 1 1/8 center to center at 50 yards & 1 3/4 center to center at 100 yards.
90 gr. Black Horn
240 gr. Gold Dot 44 cal.
Hornady green sabot
Winchester primer
Tried Harvester green crush rib sabot slid down the barrel way to easy shooting all over would not group.
Hornady sabot was a little snug but I would like to find something tighter
Would a regular green Harvester be tighter than the Hornady
any suggestions

That is some great shooting. That looks like you have a real shooter on your hands.

The next step tighter from the standard harvester is the MMP 12. Lee
