Seems to me that at least a few places were looking for a reason to drive prices up. I am indeed glad I bought an extra case of 5.56 in September, and I snag 9mm whenever I can since that’s what I shoot by far the most of. I’ve gotten to where I buy a couple boxes of HST every time I order to bolster that inventory. Would rather be able to buy the stuff a case at a time to avoid various lots, but such it is.
5.56 has definitely seen an uptick, but doesn’t really seem pistol ammo has done so.
