I know this has been covered in the past many times, but:

What is the twist rate for a .223 Ruger 1-B?

My best load so far has been a Sierra Match 52 grain w/ REloader # 15, 25.5 grains. While the factory trigger ain't so great, the rifle consistantly produces 1/2 to 3/4 inch groups, and I am not a bench rest shooter. Scope is a Nikon Buckmaster 6-18x40.

Brass: Remington
Primer: Winchester

Anyhow, I would like to know the twist rate and apparently it must be ideal for the combination above.

THANKS in advance and have a great Sunday !!

I have a #1-V in 223. The twist rate is 1 in 12.

The Ruger Factory uses 1 in 14" twist.
You can always get your cleaning rod out and check it.
