What I found was that even for round ball,ww material was 2 hard and always casted bigger. With a .490 ball out of ww...and a 15 thou patch..i couldn't get it down the barrel. I didnt even try it with a maxi slug. You can find pure lead at a plumbing supply shop. Its usually in 50 pound sheets and sells for around 2 bucks a pound. If you buy pure lead like this...you wont have a problem down the road and it sure saves a lot of head aches..
