what is the twist rate in a ruger #3 in 223 caliber?

Thank you

Probably 1:12 but I'm drawing a blank in my library. You can do the "tightly patched cleaning rod" trick and measure it yourself. Measure the length it takes for an index mark to rotate once, viola! Masking tape and a pencil or pen helps. So does a rod that has a handle that allows it to rotate.

Find the twist rate is easy...
Start a tight patch; being sure the jag is tight on the rod.
Mark the rod with a felt tip to indicate Top Dead Center and a starting point.
Advance the rod until it comes back to Top Dead Center.
Measure the distance traveled from the start mark. That is the rifling twist, one turn in xx inches.
A lot easier than trying to estimate the amount of twist in a foot.

Well, I DO KNOW the Mini-14's are 1/10".......
