Welcome to the Rohrbaugh Forum, hk_mtbr;
I've been reloading for my R9s for the past few months with good results. 100% reliable feeding & extracting, 100% reliable ignition.
I've been using primarily Winchester and Remington brass; CCI 500 primers; Berry's 115 grain bullets; starting loads of Unique, Universal Clays, Power Pistol, HS-6. I like the Hogdon HS-6 the best because it generates very little flash. (Power Pistol is a good powder, but the worst from a muzzle flash standpoint.)
From a lot of reading on the 9mm cartridge, I wanted to be very careful to not compress the charge. So I measured O.A.L of a 115 gr Winchester White Box round, disassembled the round & measured bullet length. Then I adjusted O.A.L. of the rounds I was assembling by the difference between the Berry's and Winchester bullet lengths.
The adjusted O.A.L. of my handloads fell within the range recommended in several of my reloading manuals. 100% function at the range was proof of the pudding.
