8/56..... Turn of which century!!???!!!
I had a howa that was trued and rebarrelled to 7mm-08. Shoots some very fine groups out to 600yd (haven't shot it further). I looked at going 284 but decided it wasn't suitable for the how action as I want this rifle to double for varminting.
If and when I ever have the cash, I'm building a 284shehane on a solid action.
You will find that the 7remmag will be toned down significantly by such a long heavy barrel and a beefy stock.
