A: Thanks for reaching out Jamain! They’re very similar cartridges. Both have a 175 grain Sierra MatchKing bullet. The ammo on this page is the original M118LR that is loaded with propellant which creates greater muzzle flash and is more sensitive to temperature. The MK 316 MOD 0 features IMR 4064 propellant that helps to correct those problems.
This cartridge’s open tip match bullet is not designed to expand within soft tissue. As such I would recommend ammo better suited suited deer hunting over it. This long-distance sniping ammo is meant for match shooting – if you don’t compete with it, you can fire it to judge how distant a target you can hit.

A: This ammo should function correctly in an AR-10 whether it's chambered for 308 or 7.62x51.

A: Hi Matt! This ammo is essentially M118LR, but its different notation indicates a couple special things about it. The "XM" means Lake City made it but decided to sell it to Federal instead of keeping it for government use. The "CS" just means it's bulk packaged.

A: Military specifications are very stringent and if just a few rounds out of a huge batch fail specifications, then entire lot is sold to the commercial market as Military Seconds.
It is a good chance that the rounds are from the same lot, broken down into small units for commercial sale, due to them being military seconds.

A: Hello Tom,
This XM118 ammunition from Federal is loaded with the Sierra Match King projectile. As a result, this ammunition does not contain any steel and will have no issues passing a magnet test.

A: I would not have any hesitation with the 175 grain with your rifle. If you are shooting at a moderate distance you will notice little to no differences. At longer distances, you may find yourself adjusting your sights to compensate for the heavier weight compared to the 150 grain. For any round over 175 grain, I would consider a rifle with a 1:10 twist rate.

A: This Lake City ammunition was manufactured within the last two calendar years. While exact dates of each case is not recorded for quick reference, all of our products are fresh from the manufacturer and in great condition. Any surplus stock that has been manufactured prior to the last few years will be indicated in the product description. One example of this is our Bulgarian surplus ammo from the 1970s.

A: Rifles that are chambered for 308 will safely fire the 7.62x51mm round. This will not be true for 308 in a 7.62 rifle. It is important to verify which rifle you have, as well as the type of ammo you will be firing.

A: Yes, 7.62x51mm ammo will safely fire in a 308 chambered rifle. While these two cartridges appear similar, 308 Win ammo is loaded to a higher pressure and should not be fired in a 7.62x51mm chambered rifle.
