A friend of mind in PA,has a shop
(muzzleloader) and he said that they used to lay the bullet or round ball
in their hand and pour powder overit until it was covered and this was the
amount to use for a hunting load..Now I guess this was for a round ball...

Thats what the old timers used to do to speed up reloading process. I dont think its a very accurate way, nor do i think it is safe.

Round ball powder charge can be as little as like posted above, 50gr for shorter distance, I like to start out at 80gr RS and work my way up. This year my mountain rifle will be packing 100gr RS and a patched round ball as my elk back up rifle.
