Years ago I wanted to about duplicate a 280 ross, and I had a Mk 3 that the barrel was toast. I had a gunsmith install and chamber a 7mm barrel, and for convenience I made it a 7mm rem mag. I got a walnut sporter stock, and I shoot it for fun once in a while. It is a bit heavy, but pretty well balanced. As it turns out this rifle will not handle the hottest 7 mag loads, I presume that is because of the barrel and chamber, not because of the action. The straight pull action works perfectly and feeds like a machine gun. Surely I do not have the only one.
