Yeah check daily for SGAmmo, if you’re in the need. They sent home most of their workers and I suspect they are only listing ammo are the easiest to pick (cuz less workers), and they are probably trying not to get slammed with new orders again. As of this writing they still have Magtech (good range ammo) in 115 & 124 gr 9mm.
If you’re into it, they have IMI’s 5.56 77gr OTM “Razorcore” which is a great long distance round and also does pretty well for HD/SD (its an mk262 clone) for $400 for a case of 500 which I’m pretty sure is the normal price.
