Do NOT under any circumstances feel that fitting a silencer will not cause POI issues on a new gun, even when the gun is a Diana and the silencer is a HW.

150 pellets tonight thru my new 280k 0.177 (new to me) pellet testing only to find all the inaccuracy issues were silencer related and yet nothing was clipping.

No silencer = 1 hole at 25 yards and ragged hole at 30 yards
With silencer 10 mm groups 25 yards and hopeless at 30 yards...really head scratching.

As I said, no clipping. Right now im baffled as to what the issue is with the mod fitted.
