The last decade of my career was spent carrying 45 ACP and the 230 grain W-W Ranger SXT (now relegated to Winchester White Box status, same stuff/same performance). From a 5" barrel these run at 900 FPS, and are not a "+P"-rated load. Either Lyman #452374 or the Lee 230 grain truncated cone design (conventional lube groove) duplicate that load closely with 5.5 grains of WW-231 prompting the bullets. I give that same load to my Model 625 in Starline AR brass, with about 840-850 FPS from the 4.25" barrel. Fired cases fall free of their own weight until the chambers get REALLY dirty, then the extractor gets a light tap--and out they go.
