Re: 20 moa bases

Good question, I suppose someone does or could make them, but I can't imagine the need for 20 moa bases on a rimfire rifle.

    wimmagman,
    The idea of 20 moa bases on a rimfire [22lr] came to me for 200 yard target shooting.Maybe not a good one. At the moment I use my nightforce with it's np1-rr reticle to hold over.

    Being as you have started with very simple questions, I will give you a few very simple pieces of advice. Its free so donít complain.

    First make sure you want and need 20 MOA bases. I am planning on trying a 350-450yd assault with a 22 rimfire on a local acquaintance of mine in the next four or five days now that the weather is warm and he is poking his head out. I checked my dialup and can marginally get to about 350 yds without any adjustment to the bases.

    Second, depending on which gun it is and you are a little skimpy on critical information in that category, You can just shim and bed the base you have if it is one piece.

    Third, until you have a scope mounted you may not be able to tell the alignment of the top of the receiver in relation to the barrel. It is entirely possible that your gun left the factory with some receiver slope that either helps or hinders.

    Fourth, be careful and donít get the gun set up for five hundred yds and not be able to dial back do to 25 yds.

    There is probably a fifth and sixth but I will let you have some fun on your own.

    hjl-
    I just set up my old marlin for the same thing. I used the bushnell 10x40 3200 since its got 100 inches of adjustment at 100. You could use bkl bases which let you use a weaver ring and then mount burris signatures rings with inserts. Longrange with the highpower seems a whole lot easerier after the quarter mile 22 longrifle shot.

    With a 100 yds zero you only need about 10-15 MOA to get to 200 and maybe 30-40 to get to 300yds. Lots of different speeds of ammo out there so it is hard to tell and the BCs are all goofy and the thing goes subsonic at about 100yds so it is all weird anyway. Some people advise starting off subsonic so you don't fool with the transtion.

    Well no wonder I couldn't imagine a use for 20 moa bases on a rimfire, when I think of 300 yds I think .243 [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]
