Patterned my NWTF Sx2 with 24" barrel and Indian Creek .665 shooting Hevi 3.5/2.25/7's
Less than ideal conditions with a temp of 42 degrees but it performed and I'm happy with it .
241 in the 10" and 472 total in the 20" at lasered 40 yds. Also patterned Winchester HV 5's and 6's , the 5's performed better than the 6's but none close to the Hevi's .
