KTMADV 1 Posted January 12, 2013 Report Share Posted January 12, 2013 I have a 21inch m series 308 , what are you guys seeing as far as bullet weight with the saiga for group size. I know I need to shoot my own gun but do the m series like the heavy bullets-168-175 or the light stuff like 147-150.Or does it just shoot all the weights good.

DoubleTapDrew 4 Posted January 18, 2013 Report Share Posted January 18, 2013 I don't know how it is on the 21 incher but my 16" shoots no name 147gr surplus stuff the same as it shoots 168gr FGMM at 100yds. I think the 1:10 twist doesn't help the heavier bullets like it does with 1:12 guns. Quote Link to post Share on other sites
macbeau 902 Posted January 19, 2013 Report Share Posted January 19, 2013 1:10 is what you want for heavier bullets. 1:12 - 1:14 is for NATO spec 145-155gn bullets at ~2700 fps. My S308 loves 168gn..... Quote Link to post Share on other sites
esminbritt 16 Posted January 23, 2013 Report Share Posted January 23, 2013 I shoot 168 Bernaul BTHP's real well through my 21.9" barrel .308. Quote Link to post Share on other sites
