I guess having all of the above, my preference by far goes to the Browning A bolt system. Fast, and reliable, has all of the benifits of a floorplate, without the BS of rattling shells and toploading every time you cross a road, or get in and out of the truck etc. As long as your not a butcher, the system will work flawlessly, but I've heard of guys bending the floorplate, and it not working worth a #### after. Like any rifle with an alloy floorplate, its succeptable to more damage than a steel one, but much much lighter.
I allways reload my gun the first chance get after firing, whatever I hunt. and with an extra mag for the browning, its quick, and quiet, and less fumbling when your full of adrenaline IMHO. Or, you can reload your one clip with one still in the tube if your bear hunting quickly, without ever removing the clip off the floorplate. If the need be, you slap it closed, and your back in business with no mag fumbling. My mags wont come 0ff unless you physically remove them. no opening of the floorplate, or jiggling will get it loose once its in.
I see a practical advantage, dont you?
