I only started hunting within the last 8 yrs so I'm don't know about the "good days way back when...", however this year I started shooting Heavy Shot. The steel tungsten mix loads and I have to say - I love it. I've only had one or two cripples. I did go diver hunting this last weekend and decided to shoot a box of blind side that I had from last year. Needless to say after two cripples one being a bull canvas back that flew (over a mile) out of sight, obviously wounded, caused me to put the blind side away and finish my day with heavy shot.
Both loads were #2's.
Steel is fine but I'm sold on Heavy Shot.
