I was working on a .38 Special load and bumped into a problem.
Thanks for the link. I didn’t find that when I looked today.
I got that. I'm looking for a stiff non +P load as it is.
That link doesn’t work
Well then, even that. Start low, work up.
Ditto!!! That’s best method I see to use.
Regarding your original query, I was just looking at my notes and was reminded that hornady's 9th edition lists the max load of long shot for 180 gr XTPs in 10mm automatic as 8.2 gr. for 1150 fps. Hodgdon's online pistol reloading data site states that the max load for a 180 gr sierra JHC is 9.5 gr for 1,287 fps. and 34,600 psi
I have also noticed that Hornady lists 22.6 gr of Win 296 as max for 210 gr XTPs in .41 magnum while Hodgdon lists 22 gr as max. using the exact same bullet and powder.
That minor difference would tell me to work up carefully. The vast differences in my original post had me really scratching my head.
Thanks, but it just says it is timed out.

Also interesting about that is that Hodgdon and Nosler both use a 10" barrel and the XTP reaches 1,631 fps using 22.6 grains while the Nosler JHP achieves 1599 fps using 20.5 grains. So 2.1 grains of W296 gets you 32 fps. apparently.
To me, this data just seems suspicious.
For people that shoot a lot o ammo per year it is good to remember that unjacketed ammo is better for barrel life. I like the cast bullets from Montana Bullet Works.
My basic 45 ACP load that I developed as a teenager uses a swc cast bullet and 5.7 grains of DuPont’s SR 7625. I currently use a 200 grain swc but I’ve used the same powder charge with 180 and 185 weight in grain slugs. It is a mild/medium load and great for matches. And since I’m so familiar with that load it is also my carry load because my Colt, Kimber, and Springfield 1911s all feed those SWCs reliably. It is a bit milder than shooting factory 230 grain hardball but would hit human targets very hard given the lead SWC configuration.
Well now that you mention it.... 45 acp was what I was thinking. I have to get the breathalyzer on this thing recalibrated.
The point is that any loads within your published parameters are safe, assuming your firearm is safe. Pick a starting point, load some rounds, and see how they perform. Then work up from there. That’s how we “work up” loads. Don’t overthink it.
I did not read all 73 replies- but, stick with the published recipe- primer bullet powder can ccase. each company published their loads based on testing through a pressure gun so what they say is what they experienced.
If there is one area where I may switch components, it would be brass, but always start at the low end and work up- we cannot even estimate pressure, other than when it gets obviously high, like ruptured cases and blown primers (or a blown gun...).
Never exceed published loads and use the components named int eh guide. And, since it is a 38spl and a classic revolver, stick to loads for accuracy over velocity- it is a 38 spl.
I don’t recall seeing what the purpose of the load is, but usually 125 JHPs bespeak of defense loads- my recommendation is bump up to a modern CC platform and use commercial ammo.
Were those the ones with the nickel jacketed bullet? Someone gave me some WWII vintage 9MM once and I decided to try it in a pistol. I only fired two and the second was only to see if the first was a fluke.
Montana Bullet Works is right down the road from me ... here in Montana that means within 100 miles. Going to order some up and try your basic load. Thanks for sharing.
Good advice about the lead for longer barrel life. I started off reloading with lead SWC but then those shiny bullets grabbed my attention.
In a straight walled pistol case, the bullet does make a lot of difference. If it has to be seated .100 deeper into the cases it cuts the case capacity a bunch. Without looking at the specific bullet, I can’t comment beyond that, but it’s normal. I load some 250 cast bullets for a 41 Mag, they make a bullet that is made to seat deeper so it will work in a S&W 57, the cylinder is shorter than a Ruger single action. It takes about 3 grains less powder to get the same velocity than the Ruger load.
Just a guess, but ammo loaded for an “open bolt” sub gun might use a sturdier primer to keep them from blowing out and possibly jamming the action. Detonation wouldn’t be an issue as the force of the fixed firing pin on the bolt slamming shut would be much stronger than a hammer strike.
LOL! No worries.
