Thread: 308

I put a new scope on my gun the other day and zeroed it at 200 . then went out to 400yrds and dialled up the moa and found it shooting off to the right but 4inchs could it be my reloads spinning off target or more likely the scope not straight??????

More likely a slight breeze pushing the bullet around.

Yes a 308 with 165/168 sst/amax is very capable of massive trauma @ 700y if you are pushing them above 2700fps but that really is about the maximum you can expect clean killing with good placement....with bad placement it will be bad.

The 308 is a great calibre but the wind drift really rules it out for these kind of shots at living things unless conditions are near perfect, been there got the T shirt.

Yea I think more likely wind as well. Have a look at your ballistic calculator, it wont take much wind at all to push a .308 that distance at 400yds. Correct (dial) for windage and have another crack would be the go.
