I have a Leupold Vari-X III 1.5-5x heavy duplex on my 375. More than enough magnification at 5x and about perfect at 2x. Leupold QR mounts and it is good to go to irons.
Pretty hard to beat leupold at the prices you can pick up a Vari-X III these days. Customer service is hands down the best.
Had vanguards in 30-06 & 300 WSM and never had a problem with the bolt stop. Great guns for the money if not a little heavy.
