I really don't think a 2x10x42 is that far out of line for a 375HH , tell me what ring height You need and I'll see if I have a Burris Z with a Weaver mount laying around, a picture would help
had exactly your same problem on a win 70 supergrade with a leupold it it turned out to be a gun issue not rings or scope took it to a very good gunsmith and he just shimmed the back base done deal. that was many years ago and nary a problem since. way easy fix. and i agree with what someone else said I wouldnt use weaver rings with that scope on a 375 nor burris rings either both POS not befitting such a nice scope! warne, talley, leupold and some of the custom ring and base guys all good. 375 will recoil hard and stress a big scope and the rings and mounts and you want good ones when facing down a buff.
weaver used to be great in the day, i have old ones that are awesome, not so much anymore, I would suggest that as someone else said with any off the shelf rings I would mount them and lap them, you will be surprised at how much they are out of round and dont line up. It is really easy buy the kit from brownells, you wont be sorry especially with a nice scope. A good custom gun maker usually laps rings. just drop a scope in a set of off the shelf rings and many times you are pushing it down in to bottom out or the top is squezing down as you tighten the screws thats not good lap those rings and she will drop right in with no stress on your optics. I own a firearms shop besides other things so I see lots of things and i have seen burris mount and scope failures including on my own weapon so sorry guys would never put another on my personal firearms, thats just one mans opinion. i will take leupolds and most of the european scopes all day any day and I lap the rings and mag mount the bases aka drill out tap and use bigger screws. please dont try and drill out and tap your gun yourself have a gunsmith do it!!!
No thanks But I can assure you I've done the same many times myself, when it became obvious that a different scope would be a much better fit for a particular rifle. The good news is, when you buy that next .270 or whatever, you will already have a fantastic optic that's a perfect match for it! See, I can rationalize anything.
Glad you got the issue fixed. I currently mount 30 to 40 scopes a week so I'll throw in my two cents. I will only shim a one piece base, front or rear. Shimming a two piece base stresses the scope tube because when you shim one base they are at different heights. Shimming a one piece base keeps the tube on the same plane, but on an up or down angle.
Dwight, just saying you can buy the picatinny with a built in 20moa "tilt" "no shimming " needed.
