My shooting buddy John, has coveted my HW98 virtually since I go it, to the point where he has offered me a straight swap for Daystate Ranger a couple of times. Anyways, with the help of a group on faceache he managed to get himself a tuned .177 HW98 laminate stock with less than a tin of pellets through it.
He decided that he'd like the NS Target Master 4-16x44 scope that I have for sale, but we decided to zero and chrono with the Hawke Sport HD he had temporarily mounted on the rifle. Well it grouped, but the scope run out of elevation adjustment, shooting 3-4inches low and about an inch left.
No problem, we'll swap it for my NS complete with Sportsmatch one piece mounts, which was previously on my HW98. Sorted.
Nope! WTF! This combination grouped exactly the same as the Hawke scope, low and left and again ran out of up elevation. We double checked that the arrestor pin wasn't protruding too far and raising the back of the scope.
I quickly removed the Hawke Eclipse off of my S510 (fitted with Hawke scope rings) and we fitted it to the HW98. Slight zero adjustment required, but bang on target, pardon the pun, and hasn't missed a beat since.
The following day, I fit the NS, with one piece mounts back to whence it came, my HW98. Had to back off all the previous elevation, and the rifle zeroed perfectly, and didn't miss a beat for the couple of hours I was plinking in the garden.
Any ideas what would cause the running out of elevation on two of the three scopes fitted? Why the last scope zeroed properly, and then held zero with no issues, and finally why the NS had issues on John's HW98, but not mine?
