can some one tell me the rate of twist on a pre 64 model 70 264 mag made in early 1960?

I would think 9 or 10 twist, I do know my cousins pre-64 264 WM will stabilize and shoot accurately the 140 gr partitions and 160 gr woodleigh bullets.

Good luck!

mine likes the 140 Partions as well

1-9"

Definitely 1 in 9. My pre 64, in 264 shoots 140 partitions well. I have two Sako's in 264 with 26 in barrels. They like the accubond 140's a little better. I shot quite a few 140 Bergers, but didnt like them on game.

I have 2 rugers chambered in 264 win mag I have the M77 Tang that's a 1-9 twist an I have a hawkeye that's a 1-8 twist. I have not shot either one yet the hawkeye is new unfired, both have 24 inch barrels. Is there any suggestions on loads for these guns or bullets weights for different twist rate?

Thanks Jeremy

thanks guys for the info!!

Mine's a '60 or '61, and I measured it to see what it REALLY is, and it is definitely 1:9 twist. It likes 140-grain Accubonds, too.

You might try some 120 grain Barnes.

140 Accubonds or Partitions with RL25 is magical in my 26" 264 Win Mag.

I'm gonna have to try one of those Thundering 264's one of these days Beretz.

gunner,

You need to shoot the 26 Nosler. To me it's easier to reload for than the .264 WM. I've worked with both.

To name drop, JB reportedly sold his .264 and bought the Nosler test rifle after his report on the 26. Just saying.

rcamuglia has done a lot of work with the .264 WM and prefers RL-33.

The 1:9" twist will definitely stabilize 139-142 gr long range bullets. 75-77 gr US 869 and 139 Scenars impress in my .264, but it's a Remmy action.

Now dang DF, how am i spose to have a cool pre-64 Winchester in a 26 Nosler?

Original, naw...

Bubba smithed, sure...

I have a pre-64 6.5-284...

DF

Re-barrel.

Holy fook, I have a Rube Goldberg 375 H&H.

Double holy fook, blasphemy.

Not one of yours,Gunner.

Whewww, good deal Elk.

Sorry to run off, but you know when a Wifey walks up to you in shorts, flipflops with two wire gathering baskets yo azz is being summoned to the garden.

Not a problem,I will be watering corn all night.

You're running the big pumps and I made a quick 30 minute dash for tomatoes, peppers, squash and cucumbers.

Yup,pumping the water.

Don't ya just love the way gunner hops to attention when wifey calls.

Good man, well managed....😄

DF

Yup,she has him trained!

Very funny DF and Elk, but hey, who's the first fat bastid in line with a plate in hand when she calls, 'dinners ready'...........................ME!
