My new CVA Accura MR s shooting like a Walmart gun with a Tasco scope . Can't get a group under a coffee can at 100 yards . Using Barnes 250g Spirfire tmz sabots and 90 gr BH 209 and 100 gr BH 209 . Scope is tight to the gun . Using a TC clear powder volume measure. Cci magnum primers . Been seating the load using my whole body weight every shot and even using a lead sled . Change bullet time ? What are you guys shooting in your accura ? I bought this with hopes It would be a 200 yard gun .
