AMU Model 70: 30-338 Win Twist Rate

[Toftwo]

Not a Sniper Rifle but a vintage target rifle. I bought a Pre64 Model 70 from the CMP in 30-338win. I’m finally getting around to reloading for it and am wondering what the twist rate would be. Anyone have any insight on what the AMU would have been running on their match guns back in the day?

Awesome I appreciate it! Out of curiosity what are you basing your response on? I would think it would be a 1-10 however I believe I saw something about 1-12 which is why I made the post.
Thanks again!

Most likely a 10. A rod and tight patch will tell you.

AMU shot 220 Sierra MK's for years, not doing it with a 1-12. My local range is ORSA, Oak Ridge Tennessee I shot NRA HP and Long Range for years AMU was up here all the time.

Yep, too easy to check with a rod and patch. There's assuming, and then there's knowing...
