I first test was to test my setup. I shoot 10 rounds ( 2 mags of 5) using the RMR 124gr HP-MP bullet, 4.9gr WSF, 1.120" OAL. This has been a good load for me out of my 1911. All shot at 25 yds Crony at 5' (data on target) Temp in the 60's 10-15mph wind at my back Once magazine was loaded, all shots where about 5 sec between firing. My ransom rest was auto resetting without me touching it. These loads are a retest from me shooting on bags. WSF, powder dispensed via RCBS 1500 WSP Win Brass RMR 124gr MW bullet @ 1.120" OAL The BE is 2" in dia with outer rings 1" out Next up was 4.8gr WSF 4.9gr WSF 5.0 gr WSF the winner Don't know what happen with that lonely one. At this distance I can not see where the holes are. WFS 5.1 I think something moved but don't know what. Still learning this rest. Over all I'm pleased with the results. The 5.0 was the winner when I shot from bags, so this load is fairly consistent. But tighter since I remove me out of the equation.
