[QUOTE="Fiftydriver, post: 79448, member: 10"] Arthurj, I will be range testing your rifle with a Burris one piece standard base with a set of Burris Signature rings and a Weaver Tactical 4.5-14 scope. The reason the windage adjustible base with standard screws often fails under heavy recoil or with a muzzle brake equip rifle is very simple. When you have a mounting system like this you basically have the front ring doing the work and the rear ring being the pilot. By that I mean that the front dovetail ring has about 80% of the work involved in keeping the scope sitting still under the strains of recoil. The rear ring which is clamped between the windage adjustment screws does very little as far as keeping the scope from slipping and the grip of the windage screws is totally inadiquate for this purpose. They are there to offer you windage adjustment and thats about it. When the front ring looses its grip, the rear ring will do very little to keep the scope from slipping. Often the rear ring does not loose grip on the scope body but instead it slips out from between the windage base screws. The same system using the Burris signature rings is no differnet in that the front ring does 80% of the holding work keeping the scope from slipping. The only difference is that when fitted correctly, the Burris Signature rings are said to have 200% more gripping strength then a standard ring. As such that front rings just simply grips the hell out of the scope body and does not let go!! At least not nearly as easily as a conventional ring. If you want even more stability, go with a double dovetail base with a set of signature ring or a weaver style base with a set of Z-rings. These systems are what I recommend as minimum for the type of rifle you will be using. I have yet to see a properly fitted set of Burris signature rings fail to hold a scope securely. Only one I did see fail was on a rifle where the left windage screw literally broke in half from being over tightened. The key here is degreasing everything on the base and ring system except the dovetail contact surfaces where a quality moly grease should be used. Everything else should be oil free and dry. Above this you can get into the tactical style rings and bases and they certainly have the gripping strength to easily cover your needs. Remember Alot of the stress on the scope is a result of the weight of the scope itself and the height above the axis of the bore at which it is mounted. The heavier the scope, the more serious a base and ring you need to keep it still. Also, the higher it is mounted, the more stress the scope endures under recoil and the effects of the brake under recoil. Good Shooting!! Kirby Allen(50) [/QUOTE]
