Just bought a brand new optima v2 and it has the cva scope mount and I mounted a leupold rifleman on it. Well I got it out to line it up for deer season and I can't get it to group at 100 USA I was using triple 7 pellets and triple 7 209's. I tried a Barnes sabot which shot about six inch groups with 100 grains and 150 grains. Tried shockwaves which shot about 3" groups with both previous charges. And I tried 195 grain power belts with only 100 grains which shot about the same as the shockwaves then ran out of pellets. I bought some more pellets and plan on shooting it again in a couple days an try mag load with the power belts. But I did notice that the pellets had some residue on em. They where about 3-4 years old an I'm hoping that was the problem but something tells me it's not bc my cva wolf shot fine with them. There was no delay in discharge or anything either. So wats you guys opinion? U think it's the powder or the gun or something else?
