A few weeks ago I bought some seconds bullets from RMR. My plan for these bullets will be loading them using my normal RMR 115gr FMJRN bullet loads data, with quantities of 50+. They will basically be used for my normal shooting, but no load development. That does not mean I am not going to test and evaluate them. For these bullets I will test a regular load, and will compare it with my standard new bullet data.
First things first. When I received the bullets I obviously had to take some pictures and compare them to the non-seconds bullets. I basically grabbed 10 of each and did some measurements. Following are my findings:
From the above data you can see that the seconds have less spread in the weight, but more in the length. The average length is a bit higher for the seconds, but the average weight is a bit lower and closer to the 115gr.
Just based on the data I could not see any reason why I should work up any new loads.
Probably the most noticeable difference between them is the color. The seconds has a more brass color. Here is a picture with the seconds at the bottom.
So today I loaded up 50 of the seconds bullets using W244. The plan is to do a bit of testing, and compare it head to head with some of my ammo with the non-seconds bullets. I will do just the basic accuracy and velocity testing.
Here are the bullets I loaded today. In this picture the loading is done and I am basically transferring the rounds to a 50 round box where I will affix my printed label. That is basically how I store all my loaded ammo.
Normally I don't include this information when I post information about my loads, but following are the data points I save in a spreadsheet for every load I create:
Load #: 1496-50
Cartridge: 9mm
Case: Blazer
COL: 1.125"
Crimp: FCD
Bullet: RMR 115gr FMJRNB
Powder: W244
Powder weight: 4.5gr
Primer:FED100
Load date: 10/27/2021
Total rounds: 50
Calculated cost: $6.23
I will follow up with another post at when I have completed my comparison testing between the seconds and non-seconds bullets.
