Barrel twist rate chart.

[Why not?]

Here's an interesting link I came across recently:http://www.tiropratico.com/pdf/passi_canne.pdf

All the way from 17 CCM to 460 Weatherby.

Quite a number of common rifles missing but still a helpful resource.

Thank You

That's handy and I've saved it in 'favorites' for future reference. There's a similar hard copy of info I've kept from an earlier edition of the Sierra Manual.

Very useful - thanks.

It's tough to figure manufacturers some time. The 7X57 consistently gets a 1:8.75" and faster twist, and the 7mm RUM, gets a 1:9.25". Tells me that's plenty, even for the 1.500" Barnes 175 gr TSX.
