I haven't shot .22LR in 30 years but I just priced out bricks on CTD. 50 rounds for $15? That's $.30 a round. I just loaded up on 7.62X54R for $.20 a round and I buy 5.56 NATO in bulk for $.40 a round.
If I'm going to pay $.30 each time I pull the trigger in a .22, I'd rather just pay another dime and shoot my AR. I didn't realize .22 had gotten to that price level.
