I agree with ammo on the .22LR. I was at a store the other day and found a box of 500 hollow point rounds for $19.00. Man I was sorely tempted but instead I purchased 100 rounds of higher quality stuff at $8.00 because I knew I wouldn't have any feed issues.

I think in all things there is a decision that must be made between size/weight/cost and durability.
