Depends on the cartridge you are going to shoot from the 10 incher...
I have a 445 Super Mag and I use just the 4-screw base and then good quality rings...
The T'SOB probably is one of the top in quality and durability, but more money then is required unless you have something that has more recoil than my 445 SM loaded with a power house load using the Lyman 429650 (325+ grains). Recoil is somewhat noticable!!! And, I have never sheered a screw off in the barrel...
Good-luck...BCB
