Which base should I start with?

[the once-ler]

I will be mounting my new S&B to my 700 SPS? I have a 20 moa and a 0 moa base. I plan to start in at short ranges 100 and 200m
should I start right away with the 20 moa?
Another way to put this question at these "shorter" distances which base will give me the most "optically centered" scope?

If you can start at 20 why not? Put in on and leave it alone.

btw: That's a legit question on my part as I have no clue why you shouldn't just start at 20.

I do know with the 20 moa base I will need the .92 low rings instead of the 1" med rings i have now so I may need to buy another set of rings when the 0 moa base comes in.

BTW does anyone have a 34mm lapping kit I can borrow to lap my rings??? I will pay shipping both ways and possibly a "rental" fee I just don't see spending that money if I now need it for more rings?

What kind of crap are you buying that youd have to lap the rings, good rings dont need it. Id leave the 20 MOA base on and use to 0 on something else. Here's my setup, TPS 20moa base and rings.

Go with the 20 MOA rail. S&B reccommends a canted rail, even more then 20 but 20 works very well.

You might want to rethink the .92" rings. There is a significant amount of turret below the tube. On my 5R the scope in 1.0" high rings on a 20 MOA rail leaves .079" between the rail and bottom of the turret.

Badger rail and rings. Didn't lap and saw no need to.

Re: Which base should I start with?

I'm using seekins rings and seekins bases. I just want to "minimize" any ring marks to my beautiful new S&B and I'm just thinking out loud here but by lapping I would be "truing" up the surfaces as much as possible.
BTW what do you mean by "turret and rail" clearance? that has nothing to do with how close the scope objective bell will be to the barrel and that is what I am trying to achieve right?

Re: Which base should I start with?

I doubt you need to worry about truing anything/lapping the rings when your putting the S&B on an SPS, assuming it hasn't been worked over by a smith. I'd go with the 20moa base. Nice scope by the way!!!!!

Re: Which base should I start with?

Thanks I love it.. I will go with the 20 MOA a triad pack and will try the .92's if they are too short I will go with the 1" but i think the 92s will be perfect.
BTW i did use 1 layer of brown shipping tape in my Leupold mount with that Premier and it worked very well. when I took it out it still looked new.

So if it will make you feel better, then do it.

2)"Turret to rail" clearence, or turret housing to base clearence is the distance between the bottom of your scope turret (the part the elevation, windage, and parallax knobs are attached to) and your base when mounted.

Torque your scope into rings with too little (none) clearence and you will at best have the turret contacting the base, or worse putting a permanant bend in your bender.

The clearence for the scope objective bell gets all the attention, but there are other things to consider like turret and bolt clearence. They all have to work.

Re: Which base should I start with?

Those rings are as trued up as theyre going to get, my TPS rings dont leave a mark on my scopes.
