That Jell-dog was kind enough to send some bullets (9mm Xtreme 147s size .357 and .45 Xtreme 230 RN)for testing so here are some results from his PIF and also some results with the new RMR in house 124gr FMJs.
I didn't have time to do a ladder on the RMR 124s but used an "known" good load of 4.5grs of WSF.
This load normally give me 128-130 PF with the RMR Plated FNs so I thought it would be a good starting place. With the FMJs it barely made 125 PF but shot great.
The .45 load with the Xtreme 230 RNs and 4.7 of AA#2 shot well as did the load with 4.2gr using my normal .45 bullet the 230gr RMR plated RN.
