It's funny, my first reaction was $55/box was ridiculous and to say it's time to reload, but considering the cost of supplies right now, it's not guaranteed to be such a bad deal, particularly if you want/need a JHP projectile.
Looking at the Gunbroker/show prices for some stuff lately it's not unreasonable at all. The highest prices I've seen would be $.20 for a primer, $.45 for a bullet, about $.11 for powder, and another $.40 for new brass. Now nobody here is paying full scalper prices (I hope) but dang!
Assuming the latest prices I've seen for semi-available supplies and reusing one's brass it's about $.60/round for JHP. If you pay a thousand bucks for a somewhat efficient setup it's going to take a couple thousand rounds to break even on materials but if your time is worth anything at all to you and you want to spend more time shooting than reloading it could be a LOT longer of a payback. That doesn't even cover issues like some friends I have who simply don't have enough space to set aside to make the particular mess that reloading makes. A couple thousand is not a lot for some of us, particularly those of us who reload, but for the OP it might be more shooting than he'll do in long enough that it isn't worth it.
Sorry, didn't mean to rant there, just point out that $55 seems like a lot to those of us rolling our own, but it might be just fine for the rest of our fellow shooters.
