New member here so if I'm in the wrong place, feel free to let me know. Done a number of searches before joining and this place seems to be the one regarding actual data.
Hoping someone can help a new member out with quick load data.
Short and sweet answer to “why” (since it seems people ask regarding this topic) is Father in law has a S&W model 13 (.357) but shoots 38 special out of it and thus has brass for it. Looking at basically reloading 38/44 to be used in his 357 pistol. Wanting to use the speer 135 grain gold dot hollow point. Lucky gunner tests seem to show it's pretty consistent in expansion and penetration once it gets above 1000 fps in their testing.
Now with the "why" out of the way........So far in terms of load experiment, I used Alliant 2400 as that seemed to be common for 38/44 loads, except no data for the speer 135 grain bullet. Started low which obviously doesn’t go well since 2400 seems to like a little pressure to burn right.
For what Im thinking is a 38/44 type load, seemed to be ok with speer 135 grain gold dot, at 12.9 grains of 2400, new Winchester 38 spl brass, cci primer, length at 1.45 in the crimp groove and a pretty decent crimp. Primers don’t appear to be flat and cases came right out with ease.
Grouping is good and seems to be burning clean (unlike the lighter loads). Im getting about a shade under 1,100 FPS from chronograph so everything fits my intended goals.
So finally, the question right. Will someone be willing to help me out and tell me what the pressure would pencil out to with that load. Undoubtedly I’m well over 38 special pressures, but as a matter of insurance, hoping to see if I am at or under 357 pressure, ie something like a 38/44 135 grain load.
I’m hoping to see numbers out of a 3 inch barrel as well as run numbers from a 4 inch barrel. We can list this as all “theoretical” if that makes it safer though I think this would fit as acceptable for potential 38/44 load.
Appreciate anybody willing to help with what the pressure might be close to.
Thanks
