I use ear muffs w mag n light loads w/o incident. Much of my shooting has been indoors which raises hell - you can almost "feel" the repercussion.
However, if you are a youngster and still have all your higher range intact - there is nothing w doubling up.
In my youth, I w never even consider 44 special but as I get older, I like them ! and if I can find some w a decent price tag, I intend on trying the 44 Russian out.
