Just a comment on this Question.
The 223s need a 1 in 7 or 1 in 8 twist due to the velocity with the bigger bullets.
The 22/6mm is faster than the 22/250 and they normally work best with a 1 in 12 or 1 in 14 twist.
The 223velocity is way down from the 22/250 (It can push the 75 grain 2910 ft/sec and needs
the 1 in 8 twist). some have made the 1 in 7 twist work for them and others have not. That tells
me that a 1 in 7 is marginal.
The 22/6mm pushes the 80 grain bullet over 3500 ft/sec and a 1 in 9 or 1 in 10 should work good
In my opinion.
Also this is a good place for a 3 groove barrel in my opinion.
Just some comments.
