Re: detachable mag or no detachable mag??
I agree on the fixed mag for hunting, just more comfortable to carry.
Another thing to consider is that with Remington, once set up for factory "DM" mags, you're locked in to a detachable mag system of one type or another. The bottom of the DM receiver is milled out and the feed rails are part of the magazine.
The beatings will continue until morale improves.
