    Agreed. I have several 30's I hunt with and built them on a 14" twist. I shoot up to 165 grain bullets for deer hunting.

    perceptions regarding twist rate vary I guess

    A few years ago I purchased a pre64 Palma rifle barreled action. The fellow said he was shooting 200grn bullets. It is a Obermyer 11.25 twist and in 30 cal. Being a long barrel I cut the chamber off and had it recontoured in a Shilen #4 contour. It has been on the shelf for at least 10-15yrs. I'll find a need for it someday.

    A lot of things

    can work to dictate twist rate...temperature, elevation....but I still wouldn't sell a model 70 with a 12 twist barrel unless I need or wanted to shoot long for caliber bullets in conditions that rate wouldn't deal with. Having shot a lot of CF score benchrest I have no desire to go back to the 14 twist rate that was gospel just 20-25 years ago. For a 125 gr bullet or lighter(1" jacket) 17 is just fine in my shooting environment and the rifle sure as ell kicks and torques less in the bags...much more pleasant to shoot and I think conducive to better results.

    m70 featherweight

    I just bought a model 70 featherweight in .308. Why? Because Im a glutton for punishment I guess. Its one of those parts made somewhere and put together somewhere else. Tried everything from 125s to 175s. Nothing shoots under 2 ins. Its a 1 in 12. I read somewhere where the marine snipers shoot 175 smk in their 1 in 12s. My 1 in 12 shot them about 5 or 6 ins. but I don't have a marine gunsmith putting it together either but I thought I might get hunting accuracy. So far I aint too impressed with the new model 70. My old pre 64s do a hell of a lot better than that. Doug

    re-torquing the action screws? Factory or hand loaded ammo? Parts made in Portugal and assembled in the US. Are your scope bases tight and rings properly torqued to the scope? Have you tried a different scope?

    model 70

    Yea, I went thru the drill and couldn't find anything out of whack. Im gonna try indexing the cartridges when I seat the bullet and when I chamber a round. It might be my seating die. That would be an easy fix. May need an inline seater. Doug

    possible. do you have anyway of measuring seated bullet runout? Something is amiss imo if all you can do is 2" on target at 100 yds. My guess is bedding issues or a bum barrel, but the barrel would be my last guess.

    mdel 70

    Well, I did my experiment and if I seat the bullets in the cases turned the same way and put em in the action the same place every time. By marking the head stamp. It shot under an in. I think my seating die needs replaced. Shot a snoot full of vvn 133 that didn't hurt anything either. Ill quit bad mouthin new model 70s. Not bad for a hunting rifle. thanks, Doug
