I practice speed loading my ML and it is very handy. Here in Va you can take more than 1 deer a day. On 4 occasions I've killed 2 deer with my ML from the same stand at the same time from the same herd. Often they do not know where you are and seem confused and mill about. With practice I can load and shoot an aimed shot in 25 seconds from the initial trigger pull.
With shotgun the number of multiple kills at one time is kinda large and I can't really even count them, usually at least once and sometimes 2 or 3 times a season over the last 25 years. In gun season I usually use an 870 or BPS in 12 ga or a Browining Gold in 10 ga. deer are abundant and there is no limit on antlerless and a 3 limit on antlered. Many of the places we hunt the farmers have population control tags and max deer removal is SOP. Hope all have good luck in the upcoming season.
