Meat-ammo is generally Mk318, Mk262, TSX, or some of the LE specific ammo like the 64gr gold dot or 62gr open tipped ZQ3314 that the FBI ordered. You can find over-run ammo of stuff like the ZQ3314 or M193. IMI makes pretty affordable Mk262 clones.

For plinking, any of the ammo mentioned earlier in the thread is just fine. Getting milspec / milsurp 55gr is pretty easy.

If you're engaging minute-of-man, the point of impact shift that occurs between lighter 55gr target ammo and the heavier stuff like the 77gr OTM Mk262 won't be that big of a deal until you really stretch the ranges out. I keep a case or so of 55gr training ammo around and a few magazines filled with meat-ammo.

The DDM4 is a great base rifle. Grab yourself a sling, whitelight, and an optic.

What exactly is considered a base rifle? Where does it jump from being base to something different?

Also, thanks for the heads up on ammo!

Base just means a starting point
Before adding optics, sling, etc.
