I noticed that BadgerOrdinance sells bases with a '20MOA cant' How does this affect the scopes performance and 100 yards? Is this type of base only for long distance shooting? Also, what would you recomend for a scope in the 500 to 1,000 dollar range that is variable apx 4-20, mil dot or like, hopefully front focal (is that a lot to ask?):confused:

This could become an issue when sighting in at the shorter ranges, like 100 yards/meters depending on how much elevation travel you have in the scope. If your scope doesn't have enough travel you may not be able to zero at 100 yards/meters, but the benefit is that you will have enough elevation travel at the long ranges. Depends on what range you will be doing most of the shooting and how much adjustment you have in the scope, whether you need the canted base.

Most scopes that you'd regularly be using with a 20MOA base will have the required amount of internal adjustment to get a zero at 100.

In your price range, there are a couple scopes that would work out.

This one is a killer scope for an excellent price. It now comes with mil knobs.

If you want to step up the price a little, this scope is amazing:

It depends on how your rifle and base are built. My left handed Montana Rifle Co action with a 20MOA Farrel base on it shot 15 inches high at 100 yards with the Weaver V-24 scope adjusted 2 clicks from the bottom stop.

I had to use Burris Z rings with the offset inserts to get me down to hitting 2" high at 100 yards. I really don't need the 20 MOA mount to shoot out to 1,000 yards with my combination of parts.

i have a 20moa badger ordinance on a remmy 700 p with high rings. shoots very well at 100yards.

badger stuff is heavy duty strong!

+1 On the IOR, I have the tactical 16x42, great optic

Time to revive this old thread. I've done a bit of searching on Calguns tonight, including going through all of the precision rifle pictures here. It seems a fair amount of people use the 20 MOA canted single piece base for their optics setups on various bolt action rifles - as opposed to using 0 cant bases.

For 100 yard to 200 yard ranges, assuming the optics in question have a total travel of about ~80 MOA (published, not confirmed), it sounds like having a 20 MOA cant won't be a problem to be zero'ed at 100 / 200 yards?

Thinking of planning for future longer range, but would need to hone skills and do tests at 100 / 200 yards first.

Thoughts?

That sounds about right. You have theoretically 40 MOAs travel up and down each way with 80 MOA total, so, that should be fine (generally speaking).

Eric - thanks.

Since no one really seems to be answering this thread, I did further online research and also have conluded the same, 80MOA travel total for the scope should be able to accomodate the 20MOA canted base, meaning at 100 yds, I hope to be able to have a normal zero. I'll be pretty well set for future long range shooting.

Yep, you should be good to go. Its when there are only about 50 MOA or less total internal elevation that the puckering begins when trying to get a 100 yard zero.

So for those of you who own precision target rifles, is the 20MOA base really a common thing to select, or do most people go with 0 cant bases?

Most go for 20 MOA. This puts the erector toward the middle (a little past) of its travel when you start really needing windage adjustment. Otherwise, the erector may be toward the end of its movement leaving not so much windage available to dial.

Having just installed a Leupold 20 MOA base with a Leupold Mark 4 scope I can confirm you should have no trouple at 100 yds. The Mark 4 scope has a total of 65 MOA adjustment. At 100 yds I still have two full turns of the elevation dial for down adjustment, which I think is 28 MOA.

Here, Badger 20moa base and rings with Leupy Mark 4 6.5-20x50mm LR/T M1. No problem zeroing at 100 yards.

Norbs007, thanks. I notice that you don't use a cheek rest for your rifle stock. I presume it's working out well for you as is, no cheek rest necessary? The rear cant seems like it would raise the eyepiece significantly higher to cause dificulties in lining up with the optics with your eye. How do you deal with this?
