1000+ yard .308 ballistics info help

[terpstra]

Would anybody who knows the information, or with a ballistic program capable of calculating, be able to tell me the ballistics of a 168 grain SMK driven at 2600 fps out of the muzzle of a 26" 1 in 12 barrel at distances up to about 1750 yards. If at all possible including incramements of distances like 1650 to 1750 to 1850. Its a lot to ask for but I would really appreciate any help even if it isn't exactly what I have requested. Thanks much in advance.

308 with 168 ballistics is generally "tumbling" at 900-1000. Not all guns, but most. The 175 is the LR round to go to 1000.

Using the King Family link I got the numbers of 820 fps and 255 energy. These numbers seem pretty high to me. What do you guys think are appropriate numbers?

Yup--starting mine over 2750, they were going in at a pretty fierce angle at 1000yds

stick with a 175 if you want to be competitive at 1K /ubbthreads/images/graemlins/wink.gif

I'm not worried about being competitive. I need these numbers for another reason. So does anybody have any idea of what the approximate numbers should be?

 

[Dave King]

I'm thinking you're going to be stuck with the numbers you have above. If you need more try JBM's website.

I use the King fam program all the time and the numbers seem to work with what I find in the field trajectory wise.

So, what do you need the info for?

 

[terpstra]

I can't explain it right now, but will at a later time.
