Good afternoon, Chuck. You've devoted plenty of carefully considered time and effort in evaluating a typical Pre64 Model 70, to explore its accuracy limits with modern powders and projectiles. A worthy and interesting project that should add a piece of useful knowledge to…
…the Model 70 story.
The late Jack O'Connor wrote his various Model 70 rifles (some built by the best custom stockmakers of the day) would from the bench shoot 100 yard groups averaging between 1.5 to 1.75 inches…
…. He considered these levels of accuracy more than adequate for any game hunting, including antelope and sheep.
Given your studies of this 270 caliber Model 70, would you disagree with O'Connor?
Best,
Bill
I could never disagree with Mr. O'Conner. But, I only have experience

Just my opinion, I've used the Nosler 130 grain ballistic tip bullets or years (with boat tail, for hunting, but they also print well on the target) at 58.5 grn H4831, and use that load for my son's 1952 vintage M70. Would start though at 57 grn and work my way up. Groups seemed to get…
…better with increased velocity.

Whether its my 223 (RR), 243 (Sako), 270 (Rem700 & M70), or 7MM Rem…
…Mag (Rem Sendero), they all shoot my loads with Nosler ballistic tip bullets well with MOA groups. For 30-06 (M70) I use the Speer HotCore 165 grn flat base bullets (M70).
As for factory ammo, the best Ive found for 270 is the 130 grn Federal Fusion with…
…MOA from my Rem 700, have not tried it in the M70. Winchester ammo your using for burners are just that, burners, likely good for game not so reliable for precision shooting IMHO.

…terrible. My body can't take mountain climbing anymore. If I get the urge to shoot the Model 70 after I play with these bullets I will surely try the Noslers. I did try a Nosler in the Newton but the type of rifling in the Newton would not…
…the 3 different 140 gr. boat tail bullets I tried. It likes a flat based bullet.
For about six months now I've been playing with the Model 70. I have a 6mm and a 7mm in the works that need my attention. I'm building a 6mm Br and a 284 Shehane. The Shehane is a wildcat Win 284 for 1,000

…3c. But, that is pretty minor, and it really does not bother me. Barrel date is 1935. That should not be a concern with this early made Model 70. Like any Winchester you need to have it in your hands for the final verdict.

We're not talking about ethical high lung shots at a meat animal. 170 to 200 grains of softnose lead still carrying over a thousand foot pounds of energy to the bread basket, cojones, or a knee would solve the problem,

…Griz-
I am planning to attend the Cody show, assuming that I can handle the 2000 mile drive... I hope to carry my latest "project", Model 70 s/n 12, along so I can get some feedback/critique on it.
I also know that several Model 70 experts/collectors are going to be there. Most…

Published specs in revolvers, 200 grain bullet:

And here’s one for graphic purposes, .44 Smith & Wesson Special, Target Model, 7 1/2” barrel.
