Guys, I have a box of 180 gr. XTP's I picked up on a whim for my .357 Blackhawk, and am in search of "Ruger only" load data for it. I have regular .357 cases and slightly trimmed back .357 Max. cases. Powders are 2400, H-110, and Bullseye.
Whatcha got?

You will find FA 353 only 357 loads but I don't think I have ever seen 357 Blackhawk only data....

I just want some loads that feel like I'm getting somewhere; not enough WHOMP! when I dump the trigger on factory loads!

You need a FA 353. Hunt up JT's old FA 353 loads and check them out.... He outperforms the 357 Maximum with the FA 353... Brass is the limiting factor in the FA. Primer pockets get loose early...

like axehandle i have never seen any "ruger only" loads for the .357 but the 2400 & h110 will get you some more BANG compared to the factory stuff. use a cast 190g gascheck that pour myself. just peeked at Hodgdons .357 data for the Nosler 180g. they show start @13g of h110 and max @13.5g for 1396fps from the 10inch test barrel

just checked the latest hornady manual too. shows same basic powder charge for h110 Max. also they show COAL with bullet seated to SAAMI specs around 1.6inch. that XTP slug has two cannelures and if you are using a NEW MODEL then you have got room to spare in the cylinder. i wouldnt be afraid to seat them LONG and see how much case capacity is gained with the h110. am betting you could get a lil bit extra 0OOMPH!! then |

ever sence I got that 357 215 gr SWC GC mold from Zeus, I don't have to worry about oomph from my 357 mags. It hits like a sledge hammer when used with ample amounts of H110.

Ample amount s of H110, 180grn silhoutte bullet cast from linotype, I think that's about as good as you're gonna get,.

My big problem is, where's the line between "ample" and stupid? Yes, it IS the New Model Blackhawk; I looked at the "Silhouette" loads in Speer #13, but it wasn't readily apparent whether those loads were OK in my gun.

if those old Silhouette loads willfit in your cylinder and i am pretty durn sure they will since its a New Model then you wont have any trouble. but please note that those loads are way too long if its a New Model Blackhawk FLATTOP 50th Anniversary gun

I know this isn't within the parameters of your Q, but you could buy a pound of Lil' Gun and get more velocity with those 180s at lower pressures than other powders will do for you. No muss, no fuss.
I use 15.0 gr Lil' Gun and a magnum primer in my 180-grain .357 loadings. And I shoot them from a K-frame (among others), so I'm sure your gun will handle it. This is the max charge that Hodgdon has up for a 180-grain bullet (their data uses a Nosler partition though) and their data shows 34,500 CUP - which is fine. I get 1190 fps from a 3" 65 and 1760 fps from a 20" Navy Arms 92 with this charge, using Tennessee Valley Bullets' 180-grain hardcasts.

That's in the plans, as I've seen that I can run way more velocity from my heavy .45 Colt loads without wearing my gun out as fast. |

Right on.  The one thing I'd tell you about in advance is that Lil' Gun seems to give markedly bigger spreads from short barrels than other powders. Accuracy's fine, though, and velocities are really up there. Spreads from my carbine barrel have been in the single digits . . . |

May have something to do with the fact Lil Gun is a shot gun powder? it has worked well for plinking loads in my 38s and 357s as well. IMO ample is the top of the load data chart and stupid about 3 grains higher, or when you get to compressing powder in a case, yes Iknow that statement breaks a bunch of safety rules, but the guns I've tried it in have all been in good shape and something I know would handle the extra pressure without throwing pieces of gun or case back at me.
