Visual Difference 300BLK sub vs super ammo???

[outlook8]

I've got some magazines loaded with 300BLK ammo, but I don't remember if they are subs or supers. They look pretty similar to me. Is there a way to visually tell what they are? The markings on the bottom of the case don't seem to offer any clues...

Weigh them if you can. That’s all I got

Shake them. Usually there’s very little powder compared to hypersonic rounds. I know I can tell the difference with mine by listening to them with a quick shake

If you have a scale that will weigh in grains, that’s a sure fire way to do it. The big 200+Gr subs will stand out against the 110-150gr supers.

Usually you can tell just by holding one. It’s a noticeable difference.

Agreed with others. Weigh em. Factory ammo usually is 190gr+ vs supers are 110-150. Should be a big enough to tell.

Screw ur can on and shoot one

scale is the only easy way ... they're all seated to just about the same so the part of the bullet that makes up the difference is inside the case ...

well , a bullet puller would work too if you want to take one apart.. but that's more work.
