Rgr, I'll see you around if I get some time off.
Neg, .22lr does not have enough velocity to set off the reaction needed for the Tannerite. Small caliber/rimfire or slow moving pistol calibers will not set it off. Better to stick with .223/5.56 and higher.
Yay, that's be fun Trouble. As far as Stu's comment... not sure. He can always use mine, not the best rifle, but it'll "git 'er dun".
