Actually, I didn't buy large quantities of ammo at the gun show yesterday, I just wanted to riff off that UPS ad campaign...
I did buy another ".30 cal" ammo can. I use them for storing loose range ammo, and I currently have ammo cans for .22LR, .38Spl, 9mm, .44Spl, 5.56x45, and a .50 caliber can I use for .45ACP. I think this new one will be for either .32ACP or .32 S&W Long.
I also grabbed another two 30-round P-mags. I have probably close to forty 30-rd AR mags, plus assorted 20- and 10-rd magazines. I think that comes from living through the "Assault Weapons Ban" Era of '94-'04; just like the Great Depression left my grandparents inveterate hoarders of string and rubber bands 'til their dying days, I will probably never feel like I have enough magazines on hand, but I try and keep it down to a dull roar.
The most important acquisition was in the ammunition department. I've been carrying 230gr. standard-pressure Remington Golden Saber ammunition in my CCW piece for about a decade now, and the newest ones I have are probably four years old. I'm down to a couple hundred and it's getting time to just burn them up. Unfortunately, the Golden Saber is one of the harder loads to find priced reasonably in 50-round boxes, while ammo sellers at the local show often have Federal HST or Winchester Ranger in stock, so I picked up some of each to use for function testing.
Lastly, I scooped up a box of Hornady .38 Special 125gr XTP on general principles. The number of commercial standard-pressure JHP loads in .38 is small enough that I feel compelled to buy a box any time I notice it on sale, specifically for use in older revolvers that aren't +P rated. I mean, if I ever suffered a blow to the head and decided to CCW my Model 12, I'd need something to put in the cylinder, right?
