A: It is possible to purchase this MBI .357 Sig ammo in units of 100 as well as 1,000. As we receive this from MBI, we will offer both options on our site. It may be possible the 100 rd units have sold out before the 1,000 rd cases. I would expect more to arrive in the 100rd units in the next few weeks.

Customer Reviews

Good deal Review by Jay6ft9
Was a little concerned at first because i noticed split casing as soon as I opened the package but have not had an issue from the next 300 rounds and counting. Hotter loads then I expected. Seem to be a good value and im pleased with my purchase. (Posted on 3/25/14)
Could be better Review by Duke660
Had 2 fail to fire in sig P229 out of 100 rnds. Could be better. Never had problem until trying this brand. (Posted on 3/23/14)
very pleased Review by Steve
very pleased,price ok, but hope reloads will cost a bit less, also I wish lucky gunner would inform me when my rounds are available. mbi rounds loaded,fired,and performed well down range (Posted on 3/20/14)
M B I. Reloads Review by Donald
I bought 100 in bulk pack. I hand inspected each round. 8 the casings were beat to heck. 1 was dented and did not want to chamber. So I tossed it. Loaded the 8 in a mag of my Glock and had 2 fail to eject out of 8. I loaded the remaking of the first 50 and fired them at the range. 4 fail to eject. I am not pleased with this ammo. 18% of the casings were damaged. 12% failed to eject and caused a jamb in the gun. Note they did not get stick in the slide they stuck in the chamber. I would not buy or recommend again (Posted on 2/24/14)
Great deal, great ammo Review by T.J.
Package shipped fast, arrived on time. Shoots and feeds great in my Sig 229. (Posted on 10/10/12)
Reliable ammo at a reasonable price Review by jdotson
1,000 rounds fired through my Glock 31 without any misfires or misfeeds. I've also shot 9mm, .40 S&W, and .45 ACP with the same results. Military Ballistics have met my expectations. (Posted on 1/27/12)
kick butt for less Review by jto
Feed through a Glock 32 like grass thru a cow. Already fired 500 out of the 1000. NO MALFUNCTIONS. I say 50% due to the Glock, 50% due to the rounds. (Posted on 11/30/11)
Great quality clean ammo Review by SigArmored
Military Ballistics 357. ammo is extremely clean in shooting 200 rnds I had no hang up's and no miss fires.I will be buying more in the future but would definitly like to see at least a small price drop. (Posted on 6/3/11)
Good ammo at a good price. Review by AK74play
I was surprised at the clean burning using it in a 6 inch barrel. almost no flash at night. Very accurate rounds. I would be happier with a more uniform bullet weight though. I think these should be at least 125 gr vs the 124 that they are, and even at the good price I think it should be a bit lower for reloaded ammo. All in all it is quality ammo at a pretty good price. (Posted on 4/10/11)
