300blk
For training rounds, I won't buy anything else. They are extremely consistent, phenomenally priced and the shipping is fast. 10/10 would recommend.

Best there is
Minuteman's 300BO is by far my favorite. Very consistent, reliable, and clean, at a price that can’t be beat. Lightning fast shipping. Pay no attention to the other guy’s 1 star review, you won’t find a round you like more than this!

Leaving a 1 star review because they lie about same day shipping. I haven't received the ammo to rate but won't buy from again due to shipping not being same day. Response: We apologize for the inconvenience, however your order was placed at 1:45pm EST after our 1pm EST cutoff time. The cutoff time is clearly stated on each item.
