    Looking at possibly buying a new rifle, savage 10 fcp in 308. Want a long range rifle with longer barrel, hs stock, accurate from the factory with out having to add a bunch more too it besides optics (which i already have).

    The Savage 10 FCP seems to fit the bill, but I am worried about over stabilizing the 168 grain bullets that I have become accustomed to blowing stuff up with (and I have about 1000 of them left to load, and no other rifle to shoot them out of).

    So, is 1 in 10 too much for this bullet? Would I need to step up to some heavier bullet? What says you?

    I am looking to shoot only to about 800 yards at this time, maybe more as my skills improve. Yes, I want to stay 308.

    The 1 in 10 will work just fine. In fact the 1 in 10 and the 1 in 12 are the recommended twist
    for 308 target rifles.

    With the velocities of the 308 with the 168gr bullets ( Around 2700+ ft/sec velocity )you wont
    have any of those problems.

    My 40 x target rifle has a 1 in 10 twist and I use it for 200,300,600,and 1000yard matches
    with the 168gr SMK.

    Yes "JE" is right the 1-10 twist is just fine... I myself; have used many 1-10's for my .308 projects; to tell you the truth, I had my best luck with 1-10 twist in polygonal .... for some reason they all shot great with about anything I put in them; I never received a bad one... anyway the Poly barrels shoot great and they seem to give a little better barrel life.
