The Speer LSWC 240 swaged. After years of fighting with cast bullets, these worked great after culling those with damaged bases. Uniform in weight, which meant no internal voids to unbalance things. Most folk don't shoot much past 50 yards so little things that won't matter much at "short range" make a difference further out. And "close" means zero points in IHMSA.
I could run them at a comfortable 1000 fps with no leading for thousands of rounds (with a quick tumble lube of modified Lee Liquid Alox before loading), which means less fatigue than shooting hotter loads. Especially important on Turkeys and Rams, either at Field Pistol distances or Standing Big Bore.
FP or FPAS: Turkey 75 yd, Ram 100 yards on 1/2 size targets.
BB Standing: Turkey 150m, Ram 200m.
ETA: For some reason I've never gotten the Hornady swaged bullets to do as well. And they cost more. I reckon I've spent more on bullets, powder and primers than I've spent on the revolvers...
