I think I own about 22 to 25 bolt action rifles. When I was young (back in 1988) I bought my first rifle, a Browning A-Bolt Stainless Synthetic in 7mm Rem. Mag. These were the bomb when they first came about. I also bought a Nikon 3x-9x-40mm scope, and had the store mount it. I think about a year later I bought the same gun, except in .270, but with a Nikon 3.5x-10x-50mm. Again, I forgot the name of the store, but they mounted the scope for me. However, since then, I have mounted all of my scopes myself without any problems. In fact, I must say that with my first two guns, when I took my first shots on paper at the range, the shots were way off. However, when I boresighted my scopes when I mounted them myself, would you believe that virtually all of my own mounted scopes yielded first shots pretty darn close to the bullseye? LOL! Trust me, I'm no gunsmith, but if I can do it, any body can (or at least should) be able to do it!
