'Have a pile of Burris scopes (II, Signature, E1, Veracity, IV, and even an antique gloss blue 3.5-12!). I used the compact variable power IV on heavy recoiling guns (like the Rem 700 UML that'll send a 350 gr bullet at 2,450 fps-quite similar to the 375, but they are 30mm). The others are on calibers up to 300 and .338 (no issues ever, including a 2-7x II on a .338 set up with Barnes original 300 gr softs.) They are great scopes made by people that left Leupold I believe. Never an issue that was their fault. If you're using factory ammo (and use quality mounts-Talley, Alaskan, et. al.) you should have no issues. 'Never had any issue with US scopes in 375s, but I did have an issue with the scopes sliding in the really pretty, ultra-thin (but highly disfunctional) Austrian Bock rings that came on my old Steyr-M S/T. That should be a very cheap scope as the 3-9s and 4-14s are like $150-300, but I had one on a smaller bore magnum (no issues ever and we hunted to 720 and practiced to 850 yds.) It should be ok. If not, Burris will fix or exchange it! I've sent a few to Greeley CO after breaking lenses on rocky cliffs, etc. (User Error lol) and even shot a sheep at 225 yds with cracked lenses after a fall from one ledge to another below (Signature Series 3-15x on a .257 Wby!) That (1990s) was the day I began to love Burris!!! Trijicon 1-6x is a great one too but I believe it's 30mm. And, 'can't fault the Leupold (1-5, 1.75-6 or) 2-7 either as I tested a lot of guns with one that (jumped on its own accord from box on kitchen counter to hard tile floor-dented-and shot perfectly. Now on my Son's 375.)
