Redhawk, you have a greater breadth of experience than I do with the Encore. I've had mine for a grand total of 9 months and it's a muzzleloader to boot, so I really don't have an accurate idea of the time and mechanics involved in quick reloads.
I will say that anyone can nut up under pressure, and I have seen pros do just that. I've heard the awful, loud, click of a misfire when my M4 failed to feed, and me under fire (I carried an M9 for backup then and I carry an M14 now). The point is that things go wrong sometimes, Murphy is always a possibility, and for that reason I will give myself that extra margin of safety.
Perhaps I should have said, "I will not try to make an Encore into a controlled round feed dangerous game stopping rifle", because that is what I meant. Will an Encore in 416 Rigby take down the largest on the planet with one shot? You betcha. But what if it doesn't?
