Been working with my shootin' buddy's 264 Win Mag in 26" Mod 70
He bought it right out of high school in 1967.
He harvested many mule deer, 100s of chucks, a few coyotes and hit a bull elk in the boiler room @ 30 yards, then trailed it all day and didn't get it.
About 30 years ago he put it up and hasn't shot it since. Said that's when it went south. Has around 900 rounds through it.
He was interested in going to Townsend Mt on the 20th if he could get one of his 264s shootin'.
He gave up...
I volunteered to take the project over. What frustration.
First downer I learned is that reaching a solid 3000 FPS MV is major impractical. Wholly good squat!! my 270 Win shoots 0.75 MOA @ 3325 FPS MV w/140 Bergers. And well under 0.50 MOA @ 3200 FPS MV with the same bullet.
It would seem the 129 class 6.5mm offering would be the heaviest projectile with decent performance. (This rifle shoot 100 grain Sierras lights out. Meaning lots of chucks out to 400 yes.)
Second downer. Barrel life is notably short. Research says 900 rounds is a realistic expectation if loaded and shot wisely. Wholly good squat!. . . It took 950 rounds to shoot out a 270 AM barrel and that was pushed hard in velocity and pressure. Always kept it cool though. And that's shooting distances a 264 Win can only dream of.
Third downer. What's with that barrel screw. Who's dumb idea was that??? I can see the center action screw. A decent pillar and skim bed will take care of that. But the barrel screw? Seems unnatural.
He may well rebarrel both of these rifles in, guess what? 264 Win as he has dies, bullets and tons of brass. I wouldn't! But him being only a few years younger than me and with two, using only for taking coyotes and wolves he they may out live him.
All in all I can see no practical value in the 264 Win.
Those old Mod 70s sure are sweet to carry around an shoot. Pretty much the perfectly designed hunting rig.
