bigdog---well I am guessing right now, since the gun is apart and in two places but yeah, about 10.5 pounds and yes I agree that is why I do not want to shoot real heavy loads in it. The thing is, it is a flintlock blunderbuss...

I will not use this to hunt elephants or rhinos, or even small dinosaurs. I will use it for Turkey. Maybe a hog, (although I think I prefer my double barrel 50-90 better for that fair). And the blunderbuss is to entertain myself and for making people laugh when I shoot it at targets or clays or at rondies. Sure, do I plan on shooting big-o round balls out of it? Yup. But I will not over do the powder charge just so I can approach elephant gun 4 bores.

And yes I am thinking 130 grains of real black powder under a 4 ounce round ball may be my limit with this Blunderbuss... But I will know soon. That I can guarantee!!! and I can't wait to get it back together and do my loading!
