Prime Time and Matt,
Could you give me some information on the Leupold Long Range base you mentioned. Looked in a catalog and could not see anything with that designation - do you mean the MK4?
Leupold make a STD one piece base that has about 15MOA built in. At least that's what it's supposed to be. I think they only make them for the Rem 700 and win 70 long and short action. Go to the tech support page on leupold site, go into the mount fit search. Input your rifle make model and it will tell you if it is available.
Well just to update you all on my adventure. I got the one piece LR base and installed the two front screws and the rear of the base was 0.096 off the reciever. There was almost a 10th of an inch gab between the back of the base and the top of the reciever. I guess I am calling Remington tomorrow. I want to see what they say about it. If anyone has any suggestions.....I am all ears. I'll let you know how the phone call goes tomorrow.
I loosened the action screws last night and no change.
I brought it over to a gunsmith last night and he played with it for awhile and we decided to mill the base to fit. We bore sighted the gun and it made a world of difference. He has a 100yd range behind the shop so we test fired it. I now have almost all my elevation adjustment and the scope is crystal clear. So I think the problem has been solved.
Thanks for all the responses. You all have been most helpful.
