Just curious...
Does anyone load a round in the chamber and then top off the mag?
Well, yeah, of course.. DUH!
And I don't unload 'em at the end of the day either...just in case I gotta USE one in a helluva hurry so I don't have to waste time.
Matter of fact, I've never done +1 even in my hunting rifles....
I'm just the opposite.. Load 'em to the max, I always say.. One can always wind up with an extra, but IF one needs an extra and it ain't there, yer gonna miss it - big time..
YMMV..
