MOA Help

[2manytrucks]

I'm looking at bases for my Remington 700 .338 ultra mag. I got a good deal on a scope, but it only has 20 MOA of internal adjustment (actually about 25 but still weak haha). I was interested in a 20 MOA base to give me a bit more adjustment. I'm still
new to this, by my figuring that will put me about 10-12.5 high from the start. That would mess me up at 100 yards, but I was planning on zeroing at 200, will I be ok or would that be unacheivable? I was told there is also a 15 base that might put me in there better. I realize with my severly limited scope extreme range is out of the question, Id like to get 600/750 if at all possiable. I dont see there being anyway a 30 would work, unless i zeroed way out there. Any help or input would be great, I'm tring to get set up before elk season. Thank you

For the caliber you have and it's potential for longrange work, I would look at getting a better scope with more MOA adjustment.
Look at a Sightron S3 or Vortex Viper PST and and also get a 20 MOA rail.
With this setup, you would be able to shoot out to over 1000 yards.
Or just get the scope for now, and the rail after hunting season.
These scopes have 100-120 MOA of adjustment.

I got a real good deal on this scope. I'm gonna try using it for now, next year I'm buying something that will suit this rifle better then this will go on my .17
I'm just trying to get this to work for now. Just starting out in the long range stuff and still kinda MOA confused. Am I right that I cannot obtain a 200 yard zero with a 20 MOA base? Wouldn't I have to be around 350?

Funny this thread came up today. I was at the range today sighting in my STW. I have always used 20 moa bases without elevation problems. For some reason I couldn't get my hits lower than 12"s from center, even with that elevation cranked to the lowest setting. I just put on some 0 moa bases tonight and hopefully that will work. It must because my Swarovski doesn't have as much internal adjustment. I have heard you want at least 4 moa or 16 clicks of elvation from the bottom setting so it's not so hard on erector.

Thanks for bringing that up. I totally forgot about leaving some space on the bottom. Figure I have 8 down, with a 20 would potientially put me 12 high at a 100 yards...

Using 15 MOA base or Burris Signature rings with the inserts equaling the value of 15; 225 Barnes TTSX bullets at about 3100 ft/sec with a scope height of about 1.8" Zeroed at 100 yards and shooting at 5000 ft of altitude you should have enough adjustment all the way up to between 900 and 995 yards. Seriously!

Get a 20 MOA and shim the front base as needed to get what you need would leave it so
that you have a moa so on the bottom...
Would contact Warne for a base as you may need, I have worked with them on a coulpe of
different bases. Were great to work with.

Sightron does have 100-120 depending on the scope you buy but the PST only has 65 MOA

if your only looking for 700ish yards look at the Leupold CDS scopes they are very afordable

This is where I'm confused, wouldn't even 15 MOA put me too high to xero at 100 yards?

NOoooo.... from 12.5(half) you would still have to crank it down some to zero a 100 giving you more than 12.5 of upper adjustment. The figures I gave are pretty close to
real life stuff.
