New one to me. I haven't been shooting for a few years but over the past few months I've been getting out with various air (spring & pcp) plus powder rifles including shotguns. All is fine with all except one. I can't hold it steady ?? All my shooting is rested one way or another so weight isn't an issue & most rifles have the same scopes so not the scope. There obviously is a little movement with all other rifles but one in particular is like trying to aim while running on a ploughed field wearing springs for shoes, baffled is an understatement, the cross hairs are all over the place. All my shooting is at x10.
