30-06 Question on Groups

Hi,


I would like to get some advice from you guys. I picked up a NOS Sako TRG-S (M995) with hopes of taking it on an elk hunt.
  • The twist is 1 in 11
  • The barrel length is about 23 inches
I tested it out this past weekend and it didn't seem to group with the 180 & 165 grain factory loads. Thanks goodness, my buddy had some 150 grain and I got a decent group with them.

All of the following groups were shot at 100 yards.

  • I had a solid support on the front and rear.
  • The scope is a new VX-6 3x18.
  • The Sako Optilock rings were installed per factory specs (proper inch pounds for various screws) and loc-tite where advised by Beretta USA.
  • The wind was 10 to 15 mph from the side and could change directions.
Can you guys please share your thoughts with me based on what you see with these groups?Thanks,
Dave

    Lighter bullet = faster FPS. Ya gotta drive them with an 11-1 barrel.

    Thank you for your reply Sully2.

    I'm a novice at this stuff. Just so I understand...are you saying that the lighter bullets will shoot better in the type of barrel I have?

    Is there any hope for the heavier stuff?

    Thanks a lot,
    Dave

    Your 11 twist barrel should not be a handicap with the bullets weights you tried. You are dealing with a factory barrel, new or not. They can be quite finicky about which load and bullet weight. Try some more of a different brand to see if your rifle has a preferance. I'd not expect 1/2" groups @ 100yds. from a factory barrel.

    Thank you for the hopeful thought. I'll see if I can track down some more loads.

    For many a decade the "normal" twist in an 06 was a 1/10 twist for slugs that weighed from 150 gr to 220 gr. If you constantly shot 200-220 slugs a 1/9 was what ya needed because of their slower FPS speed. If you always show say 110-135 gr slugs a 1/11 or 1/12 twist because they were already "a-zipping" down range so all you needed was enough stabilizing spin.

    Are there any fast moving 180 / 165 grain factory loads out there?

    I'm in a little bit of a fix because I purchased this specifically to shoot 180 grain.

    I guess that's the way it goes. Live and learn.

    Thanks,
    Dave
