Discovery Channel has a Dual Survival mini-marathon planned for tomorrow night; replaying the three already aired shows before the brand new Peru episode. Check your listings.
If you're looking for quiet .22lr, Aguila's Super Colibri are the way to go. Tried some out this week--about the same noise level as a pellet gun. Of course, they don't have the "oomph" to cycle a semi auto.
Suarez also has a Mini-14 gunfighting DVD coming out soon, which is the first Mini-14 specific training DVD that I've seen. If you're fond of the Mini, you should probably check this out. You can pre-order here.
