I have a PacNor barrel on a Ruger in 22.250. I originally bought the barrel and had it mounted on a Ruger 223.

I later sold the rifle with the original factory barrel and had it rechambered and put on a 22.250.

the Pac Nor had a one in 7 twist, and was 24 inch Stainless Steel.

75 ELD=M shoot quite well in it, even at 300 to 400 yds distances on targets at our local range.

don't know if the 1 in 7 twist, helps that much over the 1 in 8 twist.
