I thought there was a bolt action take down, looking like the Ar7 but named the A5- it was .22 and fit in the stock and weighed like 3 pounds, just like the ar7.
For the HR barrel in 357 here you go

Scroll down till you get to handi rifle barrels
357 357 Mag, 22" $87.00 Has udjustable open sights, a plus and what I think should be on any utility gun.
Those hr guns switching in 410 and 22 look good. But the rossi has the combo in 20 gauge and .22. It runs for 100 bucks new when on sale.
A superlight synthetic stock handi rifle weighs under 6 pounds. That's pretty light!
Seems a .223 would be good to. I have heard of people handloading it down to .22 LR like performance. Common ammo. Fellow I use to go to school with killed deer with a .223. You can get a super light handi rifle in .223 with iron sights.
Also, you can get .22 LR and .22 magnum adapters that will allow you to shoot .22 LR and .22 magnum out of your .223!
Here you go

If you like .22 hornet maybe get one of those. With iron sights on the handi rifle.
Me, I would go for the super light synthetic stock handi rifle in .357 with iron sights. But I think .223 would be good too, for my location.
