When you think of a ball-et thing of a roundball as far as powder charge. Now in a fast twist rifle, like my LK-II I shoot a 270 grain ball-et with 80 grains of powder. Its very accurate to the ranges I hunt. I would not want to shoot this thing past 100 yards. All you do is pour your powder down the bore, then set the ball-et on the muzzle, take your short starter and knock it down the bore and finish it off with your ramrod. The come pre lubed so there is really nothing to them.
In the case of the conical bullet.. if they are marketed they usually come lubed. The No Excuse Conicals have an excellent lube on them. They are a .503 diameter. Again, dump 70 grains of powder (what I shoot depending on the rifle) then set the conical on the muzzle, knock it in the bore and finish it off with the ramrod. Easy to shoot, and very deadly.
