For the price I'd say a good purchase. Out of 200 rounds maybe around 15-20 rounds that I'd assume had bad primers and didn't fire.
BWalter82 said:
This ammo is clean firing, accurate to 2 moa, and I never had a problem in any of my rifles; probably the "best bang" for the buck out there!

Def said:
This stuff is cheap, and I value that. The last 4 boxes I bought are super dirty and not polished like it is 40 year old military surplus. You can see the annealing, and it looks like it came out of an ammo can 40 yrs ago . The consistency is all over the place and I wonder why.
Jack said:
I have always put M193 as offensive/defensive ammo, which is why I purchased it in the first place. I tested 80 rounds at 25, 50, 100, and 300 yards with a Sig M400, it was dead on accurate.

Shot this on my high end Geissele rifle and very, very happy with it ... target practice
