Anyone have a link to a comprehensive twist rate chart for common firearms? Or maybe something easier than filtering through Google search results...

Barrel twist rates for the more common calibers and manufacturers is what I'm after.
Let's say I'm going to work up a load for a Winchester M70 extreme weather , Tikka, Howa 1500, & Remington 700sps all chambered in .270win and I'd like to find a copper mono that will fall within the recommend twist rate for all four of those makes.

Nor sure you can find a reference like that. Might have to go by manufacturer. mtmuley

Berger has one in the back of their loading manual.

I’ve seen one somewhere. I wish I knew where. It was quite comprehensive.

You would need year of mfg too, as sometimes twist rates change with prevailing tastes.

I think the closest you’re going to find is the SAAMI specifications. Manufacturers rarely deviate from the SAAMI twist, but I can think of instances where they do. But in general this is why 220 Swift’s still come with a rather useless 1-14” twist.

I’ve never seen a factory 270 Win that wasn’t 1-10”. But I get what you’re after in a more general context.

I picked one up, I think I might have purchased the edition that Noah took on the boat with the animals . Most of Bergers " go to " loads aren't even listed. 300wm w/ 215's isn't mentioned . .. and a slew of other common combinations aren't included.
The twist rate in the back is kinda neat, I looked up 10 of my rifles and found two listed.. not too shabby!

Thank you for for the recommendation, I appreciate it

Various x-bolt models come with a fast twist for 270, just for the record

I'm thinking they are seeing the need for faster twist rates. I'm 99% my xbolt 300win is 1-8"

Good to know. Makes the 270 Win much more appealing.

Yeah, I'd love for Berger to update their manual.
