Speer 125gr. Hollow Point Flat Base Bullets

[alorton]

There is a 300 AAC Blackout thread on here that rsilvers posted that had ballistic gel testing and the 125gr Speer TNT was one of the tested bullets if you are looking for hard data on terminal performance.

It performed ok but had a long neck length at 300 BLK velocities. Not sure if that would change with faster rounds like .308 as I haven't seen testing but I suspect it would.
