They are Hornady 150 grain FMJBT. I have a bunch of them so was wanting to give them a try. I've noticed that some of the bullets made specifically for 300 Blackout can be pricey. Shooting from a 16 inch barrel non-suppressed of course.
I'll see if I have any left. I'd be willing to measure them and pull a bullet to see what the powder charge was. I was shooting 10" suppressed so your results may be better and different anyhow. I didn't think the ones I loaded chrono'd too bad. I'll look tonight when I get home and if I have any left I'll let you know.
Mine likes IMR 4227 and Sierra 150 gr. Game King. Can't recall how many grains of powder, I'm not at home. I'll look when I get there.
I use 16.5 grains. My manual is buried under a pile of stuff so I can't get the data about it right now.
My Sierra book shows at 16.5 grains of 4227 and a COL of 2.105" you'll get 1850 fps and 1178 ft/lbs. I e-mailed Sierra, they said that would be a good deer round. This was 5 rounds at 50 yards.
