Back in the '80s and early '90s both my Dad and I were lucky enough to tag bucks large enough for us to qualify for the Maine Big Bucks Club which requires a buck to field dress at at least 200 pounds on a certified scale. My Dad's tipped the scales at 217 and mine was 225.
Also, I didn't notice any mention in any of those links of Maine's all-time heaviest buck which was taken in 1955 by a fella named Horace Hinkley and weighed 355 pounds on a certified scale (if memory serves me). Most sources say this is the 2nd largest whitetail buck ever recorded (dressed weight) with only a large Minnesota buck weighing in more, dressed (again, if my memory serves me).
Anyone who shoots a sabot bullet has had the problem with loading the next round with a dirty barrel we have all struggled with it.
Between muzzleloader shots I have done some research and testing on my own to find out what works for me for the next shot. I have been using a product called bore butter and when the muzzleloader is just sitting around I leave it caked in the barrel for protection. Have also found that if I lube my sabots with bore butter they really slide nicely down the barrel....
