My First Sniper/Precision Rifle Build

20 moa base
better to have it than not

Is the 20 moa more for extended ranges, over 500 yards? Or does it just allow more adjustment from any range?

[Jonathan Doe]

If you shoot out to about 500 yards, you don't need 20 MOA base. Most tactical scope s have enough adjustments for that range. The 20 MOA base will give you extra MOA adjustments for longer ranges when your scope doesn't have enough adjustments.

The canted base becomes more useful at extended range, beyond 600yds. What it allow you to do is ZERO your scope close to the bottom of your elevation setting, which gives you more UP elevation adjustment.

For example: If you have a scope with a TOTAL adjustment of 60moa, if everything was perfectly centered up (hardly ever the case) you would have 30moa up/30moa down. If you needed to shoot beyond 800yds, you'd run out of elevation and have to hold off.

That same scope with a 20moa canted base would give 50moa up/10moa down. That would get you to 1000yds with adjustment to spare. Of course things are rarely perfect so that extra adjustment allows for variations in scope, base, receiver.

The canted base also allows you to spend more of your time closer to the center of the optical axis of the scope.
Many scopes will show better resolution in the center than at the extreme edges of travel.
So while the 20moa base is not needed from an elevation standpoint, it's use may give you a better image through the scope when you have your elevation dialed for targets much beyond about 300yds.

Cool. Thanks also for the write ups in the precision shooting thread Randall. Some of the links from the Excel spreadsheet have died, but I am looking at the rest (in terms of rear bad (what's that for?), bi-pod, and bi-pod lock). Lot's of stuff to learn.

I just ordered a Remngton 700 SS 5R rifle directly from the factory. And, at a VIP price. Cannot wait to get it. I have another one, and it shoots great.

What bullet?

The rear bag is to steady the rifle.

So, I ordered the stuff and got it today. The scope looks incredible, can't wait to get the gun next Saturday. But when I was looking at the base the 8-40 screws look huge. I only got the fondle the rifle for a minute the other day and I though they looked smaller than that. Does it take the 8-40 screws? Or did I get the wrong one?

The remington 700 action has 6-48 tapped holes to attach scope bases.
Machining will be required if your base uses 8-40 screws.

Well, crap. Good thing I don't get to pick up the rifle till Saturday, hopefully I can get the right ones ordered between now and then.
