Given the short supply and increased demand, I have a few boxes of 5.7x28 ammunition for sale. 
Each box has 50 rounds, new, factory ammunition. 
American Federal, 40 grain bullets, $35. 
FNH SS197SR, 40 grain Hornady V-Max bullet, $40.
FNH SS198LF (Lead Free) 27 grain high performance, $50.
Cash only please; not likely to accept trades.  Please be patient as my cell phone is not linked with this email.
Meet in Colorado Springs.  Not willing to mail the ammunition.
