I bought a Henry lever action a year or so ago and was unable to get under 3" groups at 50 yds with it. I e-mailed the company and they asked me to return it to them so they could re-crown the muzzle. I live in Canada and didn't want to go through the problems that always seem to occur with Canada Customs. I took it to a local gunsmith and had it re-crowned. The results are amazing!
With Lapua Super Club ammo I shot six - 5 shot groups averaging 0.68" at 50 yds. seven groups of Lapua Trainer averaged 0.76". I have 2 Anschutz target rifles that don't do much better than that. I used a 4X Bushnell scope.
