I cast my own, use my home brew lube and they shoot just fine. They are heavier then what your calling for, but as other light bullets shoot fine, so should yours. I've driven a couple down the bore and out the bottom, (forgot the powder), and the rifling engraves well.
Here's what I do and works o.k.
Use a lot of T/C breechplug grease,
Crack the breechplug when I remember, (the kleenbore primers seem to really help)
I run a patch with borebutter down the bore between shots,
Load 80-90 grains of Pyrodex select, whatever works for you,
load a bullet,
and use a Remington kleanbore primer.
I really like the maxiballs, I've actually flipped deer clean over with them. A big slug of lead is a cool thing.
