to me it seems like rim fire ammo should be cheap. $5 for a box of 50 mach 2 or aguila is out of control. the 17 HMR and 22 mag are good hot magnum rounds at $8 - $10 a box, and that's ok, you don't plink with a 17 or 22 mag rimfire. but the Mach 2 and 17 aguila should be in the $2+- per box cost.
i think the mach 2 designers made a mistake by not using a standard 22 LR as the native case, they are produced by the zillions.
also, the aguila is basically a necked down 22LR, does the jacketed bullet component cost justify the 8 cent leap from about 2 cents per round to 10 cents per round ?
oh well, that's my 2 cents.
