    Hello,

    I was wanting to do a short barrel 308win and looking for info on how high of a SG number can I go before it goes to shit? I was thinking 3.5 was the point but I would like to hear some real world numbers and experiences.

    What’s “Long Range”? 500yds? 1000 yds? 1 mi?

    Again, it entirely depends on the bullet/velocity. I’d say under 1000 yds Berger’s calculator is spot on, and once you are stable (1.5+) you don’t gain anything by going higher. That doesn’t hold for ELR, hyper stabilized bullets, or unusual velocities. For .308 under a normal, book charge you’re good to go with 1.5.
