And if I may suggest something...there seems to be an awful lot of "old sayings" associated with muzzleloading...coined back during a different time with different knowledge...and as it turns out many of them are not necessarily strongly rooted in fact...LOL.
But there are a couple which do seem to hold water, and one of them to remember when doing load development / pattern testing is: "Little powder, more lead, shoots far, kills dead"
Go easy on the powder charges and you'll be surprised how good of a pattern you get...enjoy.
