I have a CVA Acura and I'm having trouble with grouping. I'm only getting around 2 to 3 inch groups , I think this is way too big .I'm using Triple 7 powder and I tryed 90gr 100 gr and 150gr . The bullets I'm using are 245gr Powder Belts, TC Sure Fire 230gr hollow point, TC Shock Wave 200gr and TC SW 250gr. I was thinking of trying a different powder eny sugestions. I was thinking about Jim Shockery's Gold Powder.
