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.

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.

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!

Great ammo for the price.
Nate said:
The ammo itself LOOKS beautiful compared to Lake City penetrators but I have not shot it yet so I can't comment on that. I paid more per round, but that is just the market, not Ammo.com.
Bigthiss said:
Great ammunition for the price. I used to buy the federal loose bulk ammo in 500 and 1000 but there were always at least 10-20 that were either faulty loads or misfired. This ammo is hands down the best for the price that I have purchased and shot. Highly recommend!!
