Very Informative 300 Blackout Testing

[mr.revolverguy]

Today I would also have some test loads of my favorite plinker supersonic rounds. I have previously tested these rounds and knew what it was capable of. What I would be testing is an RCBS Chargemaster against my 20 Year old RCBS Uniflow. My RCBS Chargemaster throws would also be weighed on a RCBS 5.0.5 Beam scale the same used for the uniflow. Since these loads are loaded with H110 which meters great I really didn't expect to find much difference. What I really wanted the Chargemaster for was throwing stick powder which will be tested on another day.

What you will find may be surprising.
