Have a full box (100) and a box missing either 5 or 10 rounds. I bought these by mistake trying to find a good load for my 300 BO. These were designed for subsonic 30-30 loads and will expand down to about 900 fps.
Would also work well in .308 subsonic loads, they're just a little long for the Blackout. If you wanted to spend some time in load development they'd probably work in the Blackout too, you just give up a lot of case capacity.

Will ship for $90, may have to remove from factory boxes to get them in a small flat rate box. If I do I'll put them individually in vacuum sealed bags and tape the box with reinforced packing tape.
