Okay, I'm mostly a shotgun guy, nothing fancy, just Mossberg pumps (500's and 535's).
I have a number of 22LR rifles (I'll admit it; they're Marlin 60's and Glenfields !).
I bought a T/C .243 Compass a little while back that wound up costing $160 (after rebate) because, well, just because...
Okay, this is more of a "Not Cheap But Hard to Get" Deal, but Midway has the Aquila 1-3/4" Mini Shells in
stock.
$18.79 for a box of 20 (90 cents a round).

They've sold out of the shotshells (they go quick), but the 7/8" rifled slugs...
