Anyone know what bullet this is? My father passed away last year. I found a couple magazines loaded with these. With no more in the collection of ammo I inherited
The shoulder of the round has a hard edge to it

Looks like a frangible bullet

Yes, it's a Sinterfire bullet. It could be a 42gr, 45gr or thereabouts. Drop one on a hard surface and it will likely fracture.

My experience with these type of bullets:
1) When fired from a revolver I'll often have two impacts on target, as they break as they travel trough the forcing cone and barrel.
2) If crimped too hard, they often break when chambering in an auto-loader.
3) They are effective in eliminating ricochet hazards when used on steel targets close up, but I'd suggest staying back about 10 feet when used in .308 and higher calibers.

I've found the Inceptor ARX/RNP product much more reloader-friendly and don't seem to have any of the fracturing issues.

When inquiring about a cartridge, please include the overall length of the cartridge case and any makings on the bottom around the primer. This is called the headstamp and is where cartridges are marked.

I thought the fact I titled the thread “5.56” and put the round on a STANAG mag for the phots kinda dialed us in on what caliber it is

Usually I would if I didn’t know that info already

I was about to make a thread like this, but I'll put it here instead.
Got a bunch in trade for an optic a while back but I don't know anything about it

Run of the mill 855 ammo on stripper clips lake city brass is mostly great stuff.
Get a mag spoon and you can feed mags from the strippers
