Re: Remington Mtn Rifle in .280 Caliber
It all depends on what you want.
The 280 is an oddball caliber. Not many know about it and many don't care. I think it is a great caliber and makes a fine hunting cartridge.
If you don't want to reload (Many don't) it is not a big deal. Trade the rifle in for something you like and want or need.
I don't think the 280 is going to make a big popularity jump any time soon so....
I myself would keep it but that is me I have a reloading set up.
