9mm Luger New Brass RMI Cases (NEW)

Description

These are brand new and unfired cases. For a very long time we have wanted to provide cases but the cost and quality of what was available just didn’t seem to line up in a way that allowed us to make money and still provide a good product. Well, we at RMR were involved in the quality and tolerances of these cases and I can tell you that there is not a higher quality casing out there. These were specifically designed to allow deep seating with a 147 grain or heavier bullet without causing a bulge. Each casing is optically scanned for the tightest of tolerances in the rim, length, diameter, flash hole, primer pocket diameter, and even headstamp. I absolutely love these cases and I’m positive you will too.

Preliminary: Received 1,000 on the dot. After pulling the sizing handle on a sample, I decided to size before sorting. Got the following lengths/qty’s:
.748″ 80, .749″ 182, .750″ 215, .751″ 249, .752″ 173, .753″ 101. I did have to trim a smidge from 42 ea that had high spots of > .754″ Just knocked them down to .7535. The average length of these is a bit longer than Starline which is OK because 9mm tends to shrink over time (I load +P). The base size is .3885 – .389. The thickness at the case mouth varies a bit (.003) when several measurements are taken. I have not loaded/fired any yet. I will update on how they perform later. This is a good price for new cases / to keep cost down need to load at least 6 times to get to <= 2 cents each. So far very good. If I can get a good number of reloads from each case, this may be my go to for new cases. Also packaged well with 1000 ea 124 gr RMR Nukes – no damage even shipping USPS:)

I purchased 21k and got what I expected.. Packaged very well and arrived still intact. I haven’t done anything other than look at a few. They are Purdy. I’ll follow up after I get my new one arm bandit up and dialed in.

Nice product. I purchase some hollow points a few months ago. I can see this all going together well. Thanks again

Used Mitutoyo digital caliper for testing
Used an AND FX-120i balance for weighing

Considering the cost of this brass, these cases are very good and I’m happy with my purchase. The cases I measured are in spec. I loaded up 30 cases with the 124 RMR Nukes. The loading was easy, primer pockets are smooth, firm, and consistent. The load of WSF powder created low extreme spreads with this case and bullet combo.

I bought 3,000 9mm cases to use for major matches such as USPSA Area and Nationals. I took 50 cases and weighed, measures OAL, and rim diameter. All were in SAAMI specifications and very consistent. I shoot Major power factor in USPSA open division. My standard deviation was 3 for my open gun load and 5 for my better half’s minor load for carry optics division. I will continue to use these cases for all my major match loads.

i have purchased in the 10’s of thousands of RMR new brass and i think i had 1 that was cracked and that is it… all of my loads check perfectly. i went from having to roll all my brass in order for them to spec and even at that 1/10 would be proud.. now i just deal with new brass for all my matches… i shoot 9mm major and i load them really hot ( 175-177 power factor) Thanks RMR for being so consistent and amazing!
