Hoping to get some advice on M98 receivers.
I have an Interarm/Whitworth 375 H&H on its way. Been looking for a one piece (preferably) scope mount. Came across the Warne M960M, but it appears to only have one hole to secure the rear of the mount. Went to Warnes web site to check the fit. That's where I came across references to altered and unaltered M98 receivers. What's the difference between the two?
FWIW, several years ago I had a Whitworth Express in 30-06 that had rebored to 9.3x62. Ask I recall finding a scope base was a little bit of a challenge and frankly don't remember what I ended up with.
I currently have Interarms Mark X in 7x57. It came with a 1 pc Redfield base and Leupold Std rings. It looks to only be secured at rear by one screw, although there could be another hidden under the rear ring.
Bottom line is what are my options for a 1 pc Weaver-style base for my in-transit Whitworth 375?
