308 LR set up

bingo1010 · #1 01-18-2008, 07:40 AM

does any one out there know if i put a 20 moa base on a 308 if i will be able to zero at 200 yards with a scope with 40 moa internal adjustment? want to shoot from 200 - 1000 but don't want to fork out the cash for a high end leupold tactical ( and the resulting internal adjustment) thanks. i did some rough figuring and with roughly 440" of total drop at 1000 yards it will be close....i think. help someone...please

Shouldn't be a problem with a 20MOA base.
However, if you get the proper reticle on your scope, there will be no problem at all.

IOR valdada and leupold both make excellent scopes and reticles for going from close to far with the the 308.
I've owned several and shot them all the way out to 1K with 6.5WSM, 6BR, 308 , and .223.
These were rifles with fast twists and 28" to 30" barrels however......

this thing is a standard rem barrel job( 26" varmint fluted) ,what is the max bullet weight you have found these barrels to stabilize properly? the 180 should be ok but i was more thinking about the200 or even the 220. the drop is roughly the same on them all once you get out to 1 k

I know a lot of fellas use the 175 match king for their long range stuff with the LTR's etc.
I have no experience with the standard length "sporter barrels " however.
All my serious long range shooting has been done with custom barreled
rilfes.
I do know that they will get out there however.
Silverado had his LTR ( factory barrel)to Homestead a while back and shot it long .
The bigges problem with the 308 is getting those 200's going fast enough!
That's why most fellas stick with the 175 - it willl and does getrdun without too mmuch fussing about.

I've shot Palma ( 155 grain Seirra) with irons out there, no sweat.

i will be putting a cheapie bushnell on it for now till i come up with some more scratch. has 40 moa total internal adjustment... hope this will work up close as well as out there

I shoot both an Accuracy Int'l and a Rem LTR with 20" barrels and have had no problem reaching the 1000yd mark with 168gr Match Kings and A-maxs. (I know 175's MK's or 155gr Lapuas would be better, but shoot what ya got)

This is at Sibbald flats and the elevation does help. Dial up is right around the 37MOA mark from a 100yd zero. So with your 20moa base you won't have a problem getting there. Don't see it being much of a problem getting dialed back down to 200, but it will depend on how the scope initially sits on your rifle.

As far as your twist rate goes. Some guys have been testing the new 208gr A-max and it has been working, but I personally think that driving the 155gr Lapua fast or using the 175gr Match King or 178gr A-max would be a better option.

If the Bushnell you are putting on it is the 3200 10X mildot one it should go to 1000 without the need for the bases.

review

I have one and it is a great scope for the price.

sorry, didn't see the specs for your scope (provided)

My 4200 6-24x50 with 42 MOA adj. with TPS 20 MOA base is zeroed at 100 m and I can almost, but no quite dial into 1000... Surprisingly, I am still about centred in the adjustment range with a 100 m zero

I'm surprised the 168's shot well at 1,000, they are designed for 300 meter internatiol match shooting, and tend to fall off fast after about 500....

how can it be that with the 20 moa base you are in the middle of your scope adjustment?

I would like to know that as well - anyone ?? Maybe it has something to do with the scope centered 2" above bore center line, or perhaps the 20 MOA base (TPS) I have is actually 0 MOA, although it is stamped 20 MOA ? It does work well for me out to 800 or so, and after that, I use the mils for holdover if need be.

Cat we were surprised too. All the books said it wouldn't happen, but none of us and there were 8 had a problem. We wouldn't win any prizes for group size I'm sure, but they were getting there. I think the 4500ft of elevation helps. Like I said though if I had a choice we would have been shooting something else.
