Bought from them a couple times. Then bought the same thing from Sportsmans guide and saw that ammotogo was charging me $15 more for shipping than SG (35ish lb can of 7.62 Tok).
I've used them with good results. The only problem I had was getting some factory reloaded softpoint .223. Lots of cracked cases/dented throats etc. They were easy to deal with on getting it replaced. Lesson learned though. You'll be good to go on factory fresh ammo.
