I have a savage 111 chambered in 270 win. Measuring 1-9 twist. Barrel is stamped A3,M and sa or 90 by the nut. I have been hunting with this rifle close to 15 years and want to start reloading for distance but all the the data I have found is based on 1-10 twist. Has anyone seen this before and where can I find reloading information for this twist rate?

Will twist affect what powder I should be using?
no....

It actually affects nothing, other than a slight affect on how it could stabilize bullets of heavier weight.Originally Posted by Porm_syndrom
Jack OConner was a diehard 270 fan. He preferred using 4320 powder in 06 size cases like the 270 is
because it flows thru a powder measure well due to the grain size.
He was correct it does, and It also produces very good accuracy, so id reccomend you try it.
Will do thank you for the advice.
