Ditto. I also like the Winchester SXT +P 130g for .38 spl.
Yeah, it's a damned respectable load. I strongly suspect the Speer 135 38+P is better but not by a lot. The Winnie 130 is a load I'd use if I couldn't find the 135s.
Jim March: correct me if I'm wrong, but aren't Gold Dots and Golden Sabers very similar? From my reading, I seem to recall Dots expanded a bit more, but Sabers penetrated better?
No, they're different tech.
The Golden Saber is a "Facklerite" load...the brass jacket delays the expansion and does allow a deep punch, at the expense of wound channel width. The jacket isn't all THAT tightly bonded to the lead core so if it's "overdriven" it can separate.
The Gold Dot is a copper jacket electroplated to the lead. It's VERY tightly bound to the lead and strongly resists jacket/lead separation. That lets the jacket "petals" cling to the lead and hold them all together. They respond very well to being "overdriven" past their design specs and are one of the only three expanding handgun projectiles I'd trust to hold together out of a carbine or rifle. I'd also trust the DPX of course...it certainly won't separate from lead either as it ain't got no lead, and the Hornady XTP is a good high-speed choice too.
Speer varies the hollowpoint cavity size and shape for the expected speed range. The 125gr 357mag high speed variant slug is technically a "hollowpoint" but it's little more than a dimple at the nose. Doesn't matter, it'll still work at any speed past 1,300-1,350ish. Speer loads them to 1,450ish at the muzzle, Buffalo Bore a LOT more for full size guns.
Anyways. Buffalo Bore and Doubletap run Gold Dot slugs at crazy velocities knowing they'll still hold up. Well...Buffalo Bore does, Doubletap have been experimenting with other slugs and failing bigtime of late in some calibers including 357mag.
The downside to the DPX is that being less dense than lead for the weight class, you get less case capacity therefore less pressure and velocity. The upside is that you get more bearing surface (bullet rubbing on barrel innards) and hence accuracy goes up for the weight class. A 125gr DPX has the bearing surface of a 140gr or more conventional JHP.
But Cor-Bon only loads the 125gr 357mag DPX to about 1,250fps. I'd much rather have Buffalo Bore or Doubletap Gold Dots doing almost 1,600fps for damn near double the energy, because I carry a BIG 357 gun (42oz) therefore I can control big power. But in, say, my friend's classic S&W 66 3" barrel, the DPX would start to look REAL nice...damn near perfect. Won't tear the gun up, controllable, very accurate. What's not to like?
