I'm not sure it's not me, one of the reason's I'm asking. Shooting handloads mainly, some commercial match. I can shoot sub moa with other rifles, and sometimes with this one. A friend with much more rifle experience than me has shot the RPR with the same results. I can call my shots with a pistol. I see the crosshairs when the gun goes off and the bullet doesn't always go there. I would assume this would work with a rifle at 100 yards, please set me straight if I'm wrong. I got access to a rifle range about a year ago and have been there nearly every weekend for the last year. (The scope is an Athlon Cronos, everything is torqued)
