For pure accuracy to 50 yards in a handgun, the HBWC has always given me the best results--32 or 38 caliber. I had usage of a Walther GSP-C in 32 S&W Long WC for several months, and worked up a load for it using Hornady HBWCs. Miniscule amounts of WW-231 and Bullseye sent them into 25 yard chrysanthemums <1" CTC, and well under 2" at 50. I have kind of been jonesing for a GSP of my own ever since, but the tariff is a bit much for this here fixed-income reprobate. Little Sister lets me load HBWCs for her M-10/Davis barrel PPC gun, 3.0 grains of WW-231 under the Hornady 148s work perfectly for her. She is REALLY GOOD, and likes Big Brother's ammo for her practice fodder, since it dupes the Super-X W-W ammo that gets used in competitions. 200-250 per year keeps her sharp.
So I have gotten by all right with cast SWCs and raggedy Rugers, so-so S&Ws, and the occasional Colt. If I was a serious target shooter, I might go about things differently--but I would need to get GOOD at it before getting SERIOUS. Those great groups with the GSP were done in the days when I was still immortal
and had better vision and fewer miles on the chassis and running gear. I can still tag out a badger or coyote with a 357 revolver at 50-60 yards, but it isn't 2nd nature any more--I gotta pay attention to what I'm doing.
Per Ed Barris, Ruger S/A 357s run a 1-16" twist, Ruger D/A and S&W 357s run a 1/18-3/4 twist, and Colt runs a 1-14". My BisHawk 357 runs #358156, #358430, and a Lee GB 180 grain FNGC with fine accuracy from 700-1400 FPS+. I am not sure that it matters, from 1-14" to 1-20", with the short squatty bullets involved in revolver shooting. Some folks with lots more experience than I have--like Ed Harris, for example--seen to think that the slower twists are meant for 110-125 grain bullets. My experience has been that longer bullets shoot better in all 357s than do the 110s and 125s, since my belief is that the bullet bases are freed from chamber throat direction before their shorter drive body portions are fully engraved into the forcing cone, and bullets are subject to canting if unsupported. Dunno.
All this to say.......HB/HP bullets have their place, I just don't want to produce them. I can't make a target bullet as good as the Hornady, Speer, or Remington HBWCs, and I can't see a difference between how my BBSPs and a homogenous-alloy casting from the same cavity print downrange. That's my story, and I'm stickin' to it.
