.223 - 1 in 11"?
« on: December 03, 2012, 11:14:40 AM »
I have a handi rifle in .223, SN ND248XXX.  It is marked SB-2.
I measured the twist with a cleaning rod with a tape flag on it, twice.  The measurement gives it a twist of 1:11".
Knowing that the published twists of the .223 handi rifles are 9" and 12", I wonder what I have on my hands.  I bought it thinking that it's age would make it a 1-12" to burn up a pile of 45 gr. bullets I happened upon. 
Has anyone ever heard of this particular twist?

Nope, that's strange. I would check to see if it's a factory fitted barrel, check to see if it's ejector or extractor and check the manufacture date of the reciver if it is factory fitted.

Thanks, Dinny

It looks like at least one other person has one.

All late H&R 223 barrels are 1:9", anything made after about 2007, yours is likely just as Doc said or built at the end of rifling tool life making it an oddball, standard twist for all H&Rs are listed in the FAQs.  ;)
