9mm WSF and RMR 124gr MW test

[Blue68f100]

Shot some test loads yesterday using my new home built Ransom rest. I did make a slight mod and moved the remote trigger bar downward, so brass ejection does not hit it. I attached my rest using a single 5/16" x 2.5" lag screw into my bench in the front, and c-clamp at the back. This position allowed me to sit down and run the trigger. I do know any movement of me will impact the POI.

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.

Thanks for continuing the ransom rest test data for WSF.

Indeed. Nice to see someone with a Ransom Rest to tighten up the results!

We also have had excellent test results with WSF in various bullet weights in 9mm.

Thanks for sharing! I would be pleased with the 4.8gr WSF results as well. Either load is well over minor, although I couldn’t quite make out the 5.0 Vavg. Any chance you’re going to try a faster powder?

1180 fps is the average for the 5.0 gr WSF. I've shot some with WST which is faster, in another thread. It did not do as good as I expected. Have some 231 but WSF has always preformed better in the 9mm.

I'm still tweaking on my rest. I see things that show up makes me wonder if it's returning back to the same spot, or my gun has a little more play than I like. I do know it was a compromise since I fitted 2 uppers to the 1 lower. 1 has a slightly looser fit. Just something else for me to check on.

Any pics of your "Blue" rest?

WSF is a great powder for 9MM. I have loaded thousands of rounds with it. Great with plated bullets.

Do you have any results for WSF and 147s?

Sorry if there's another post and I missed it.

 

[Blue68f100]

I don't have any 147's to test with.

I did have a request for HAP/XTP's 115gr and 124gr. Loaded some up this afternoon. Now just need to catch some good weather and time.
