it is a one in 12" rate of twist good for up to 55 gr. bullets may stabalize some 60 gr but heavier bullets may suffer in accuracy..... Turns out that ALL H&R/NEF .223 barrels made will be 1-9 twist starting in 2006. This is great news to those of us who want an inexpencive .223 rifle that can shoot heavy bullets.
Them twist rate of a Winchester model 70 rifle in .223 Rem.is 1"in 9".
$200-$250, depending on condition.
No published sn data. You will have to call the factory.
More accurate than 90 percent of the people who will shoot it.
1- 12 twist
This rifle was designed to handle 55gr.bullets of lighter.I do not believe that the heavier 62gr will stabilize with the rate of twist of the mini-14.

The one issue with 5.56 in a handi rifle is the harder primers. You will almost absolutely have to install a heavier hammer spring. I have some Malaysian 5.56 and it often won't fire in the handi. I have heard the same about the Rossi single shots. As far as your concerns about pressures, the Handi handles all sorts of calibers on the same frame and barrel blank. Many of those push 65k or so. I don't worry about any difference in 223/556.
