Been working with a new Pac Nor prethreaded/chambered SS Super match heavy barrel and got this awesome test group at 200yds. My best 3 shot group ever at this distance.
The math is off. Should be 0.056" and 0.028min.
Nothing fancy in the components - 80gr Bergers, Win brass, CCI 450 primers, Varget. Lee collet die and RCBS standard seating die for a 221 Fireball.
Other groups show the pipe can shoot in the 1's so am very pleased for a long range varminting rig.
