My smith here in Germany had fitted two 30mm new S&B scopes onto my Win 100 rifle for me using EAW swing off mounts that were ordered from EAW to be specific for this rifle. The rear riser block was 5mm high on both scopes but I could not get the variable 56er to hit the target even with the vertical adjustment bottomed out - but the straight tubed variable scope intended for driven boar was on the button with only two shots.
I was at his workshop yesterday and we went through all the checks and the end result was that we needed a 5.5mm riser for the 56er to be able to hit the bull with the vertical adjustment centralised.
Very strange as 2x the same make 30mm scopes fitted onto identical mounts.
He then fitted a set of EAW mounts onto a new Fabarm bolt action 30-06 while I was there at the shop in just 20 minutes clean all metals then a 2K adhesive plus screwing and adjusting all fits with the bore pin gizmo also this was for 2x scopes a used driven and a new Minox 56er.
Then we went down to the range as we are mates and mine then functioned fine but the new Fabarm he had put the mounts onto was a piece of ***** (the bolt would not close on a round without extreme force, extractor threw emptys way out when and the magazine was 75% of the time unable to be removed without his wiggle/thump skills.
Stay away from this make IMO.
