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.

If they were both weighed on the 505, how could there be any difference?
