I have a savage .243 with a 1 in 9.5 twist with 22" barrel .went out this weekend to give it the first shots .groups of 1 inch at 100 yards . I'm using Barnes 85gr tsx with 45.5 gr of hunter powder . not so good . any help with this . as I live in a lead free zone I need to stay with the lead free stuff and have had great luck with barnes with all my other rifles.
