This is a take off of this the thread Tom396 posted about Walmart. I sent the info. that WalMart was selling Lake City ammo to a buddy that works in the defense industry. I gave him this from the WalMart website: XM193 Lake City on Stripper Clips - 55 grain bullets. Below is his response:
Careful on any ammo with the “X” prefix. It can mean experimental or out of spec.
X is ammo which didn’t pass the stringent gubmint guidelines for their base ammo specification.
The manufacturer didn’t get the contract because it didn’t pass. ( usually from velocity and accuracy variations outside of the quality specification).
So whatever quantity was submitted and manufactured is sitting around can be sold as XM--- by the original manufacturer. The government won’t buy it.
XM 855 has the same bullet 62 grain steel/lead core FMJ round. XM 193 is the 55g FMJ lead core only.
XM marked ammo is always much cheaper than the other approved ammo.
The Walmart ammo is probably fine to shoot but beware it's not approved Mil Spec.
