223 Twist Rate

Most likely 1:12", but 1:9" barrels have been made too. The only way to know for sure is check it, info on how can be found in the FAQs. ;)

I just tested my '06 .223 ultra varmint and it's a 1/12.  I've heard it doesn't seem to make much of a difference (1/9 or 1/12) with H&R because the 1/9 still won't shoot the heavy bullets very well.

68gr is the heaviest I've seen reported to shoot decent in the 1:9" H&R/NEF, typically, 63gr/64gr is tops, with 60gr or lighter being the best choice of the heavier bullets. Both twist rates shoot the 40gr-55gr excellent for the most part.

Thanks Quick!  I have some 68 gr Black Hills I tried in my Tikka today but the 1:12 throws them all over.  Unlike the 50-55 gr it's a tackdriver. 

My thought is to pick up a H&R 1:9 and put on my 22 mag receiver SB1 so I can shoot the heavier lead.

As I posted to your classified question, you can't put a centerfire barrel on a rimfire frame for anything more than looks, the firing pin won't hit the primer, so it won't work. ???

My 1 in 9" 223 heavy shot 64g O K. 1.5 to 2" groups.
It will shoot 45g hollow points inside an inch though.
Works just fine for me.
I use it for coyotes all year and then sight in for heavy bullets for two weeks as my backup deer rifle.

Everything that is stated here. I have a '06 handi .223 and have never bothered to check the twist on my own.  It is a tack driver with rounds from 45gr. to 55gr.  I never tried anything heavier becuase I never needed to.  I had the shop I bought it ask the rep at H&R and they told him either 1:9 or 1:12. I think the only way to tell is to do the rod test.  Goodluck with everything.
