Can't do it with a .223 rem, the .223 wssm is shorter.
Just for the record you could chamber it if you stared with a hornet, not a good idea though. The wsm and wssm are loaded to a much higher pressure then anything NEF/H&R chambers for. I know at first even T/C recommended not to make a barrel for the Encore in these chamberings, maybe that has changed but it sounded like there was just too much pressure for a break action gun. Also without having a long barrel you are just using a lot of powder to go where you can get a .22-250 to go with a lot less fuss.

There is going to be an Utra Varmint next year with a 24" fluted barrel. It's going to be available in .22-250 and this is probably the max you are going to get. You could probably get one in .223 and have it rechambered to .22-250AI and gain a little but I don't think it would be worth the effort.

The .270 Win is chambered in the handi and has a normal max pressure of 65000. The .223wssm has a pressure listing of 62000-64000 according to my reloading manuals. But, I assume case head size enters into the equation. :?

Yep, should have probably said the amount of pressure on the receiver is more.

Just out of curiosity I ran the data on the .223 WSSM and the .243 Win. Using the factory numbers with 55gr bullets the old .243 Win has the edge. And you can use much heavier bullets and have a pretty good medium deer gun with a stock .243. It may make me rethink the idea of getting a .25-06 in the future and look at the .243 Win for a duel purpose round.

The problem is one of diameter, the 223 WSSM has a larger diameter case than the Handi is made to handle. Assuming the pressure is the same, as the diameter increases, so does the pressure on the case head. The Handi is designed for safe operation at pressures of 60,000 psi with case head diameters of .472, the 30-06 family. Graduating to cases of .512 and greater simply exceed the strength of the action, and it streaches beyond it's elastic limit, this is why the Handi is not offered in magnum chamberings.
