thank you huntin1 for all the info and advise and now that i think about i remember one of my buddies telling me about sterlok so i will give it a look too.

and 30-06shooter thank you too.

i am going to look at bases at cabela's this week just to see whats out there physically and take my calipers and try to measure some of them. i don't want to jump on anything till i can sort of confirm what i need. but what ever i go with it will have 20 moa built in and if its a base my Burris rings are still good for 0, 10 or 20 moa of adjustment.

i don't know for sure that i will shoot out to 1000 yards or not and it may be a dream but at least i can practice out to 600 for now until i get good at this.

thanks everyone for the replies and help!
