I'm looking for steel rings & mounts for my Savage Striker .308. If I go Leupold they only offer a 1-piece base for my gun.
I'd rather have 2 piece bases with 4 screws holding it down, are the 2 screws holding down a 1-piece base adequate?

I had a bad go of it at the range this week. The factory aluminum base on the Striker was moving (back & forth very slightly, but moving nonetheless) after about 10 shots. The screws were still very tight and hard to get out (I red bottle lock tighten them in). There was just slack in the base itself.
The Weaver quad lock rings appeared to have allowed the scope to move also. I placed a small (.005 lead) pencil line on the underside of the scope tube as close to the rings as possible on each side, front and back. After shooting the 10 rounds the scope looks to have ever so slightly moved forward.
Is forwardthe direction a pistol scope normally slips?

I saw a link to website a while back with a guy who's a good gun/scope guru to order from. Anybody have that site?

My main question- one piece Leupold bases OK for a hard-hitting pistol?
If not, who sells two piece steel bases for a Striker?


Thank for the help.
