RMR 124 MPR 9mm

[Daniel Rassier]

My go to load for everything is 3.2 of Clays with this bullet. It shoots very small groups at 25 yards in my SIG’s

Thanks for the share. What is your OAL and also, do you use a flat seating die or round nose?

For practical shooting in IDPA and USPSA.
This load makes 132 power factor from an OEM Sig Sauer 320 X5 Legion barrel

Bullet: RMR 124 MPR (JHP)
OAL: 1.07″
Powder: Alliant Sport Pistol @ 4.1gn
Primer: CCI 500

The OAL of 1.07″ is my “universal” Cartridge length was used to share compatibility with the 320 X5 Legion and a Glock 17 Gen 5.

I use the Redding competition seating die (with micrometer) which has a concave seating stem.

Michael, thank you for the detailed and very helpful information. I will be reloading my 124 MRS soon.
