Probably 12 years back, the guys at our gun club went through a "Snider phase".  Most used the same approach.  Some used the more costly brass cases from Brazil.  Accuracy was never great, although some of the guys really tried.  Pure lead bullets & lots of lube helped.  Also some sort of load compression and a wad.  The most fun part of our matches was "volley fire on command".  And Kipling poetry read aloud by Bob, the instigator, who was also the history teacher at our local high school. 

Bob was also a wine guy.  When he passed away, his long-time lady friend held a wake.  We drank up most of his wine collection and fired a blank salute from our Sniders and similar military rifles.
