I spoke with Phil at Innovative Arms about shooting 22LR in my specific can. He said, no worries, blast away but put 15-20rds of 5.56 through the can every 200-300 rds of 22 LR. The problem, as he explained, with other cans is that they have small holes or just holes the can/will get clogged with lead/carbon. This can has a mono-core design that doesn't have any small hole, just the center hole that the bullet flies through. He said the blast chambers are large enough that they will never clog as long as you stick with the "maintenance" schedule.
So as a general rule, 22LR in 5.56 can, bad mojo. 22LR in my specific can, good to go.
I'm still getting a 22LR can.
