Thank you. Waiting for my next day off to try loads with both cast and J-word bullets as well. When the well is dry you use what you can find!

Just found this thread.
I loaded some 125 grain (hunters supply, .356 diameter) according to Lee’s data for HS-6=5.9 to 6.6 gn MAX.
Data:
Hunter supply 125 grain LRN
Powder HS-6, Load weight 6.4 to 6.5 grains (checked every 10 rounds after a stable throw is established).
Brass .FC.
CCI SP primers
Dillon press & dies.
CZ75 BD
COAL based on the plunk test (the COAL was not off at all from what lee said it should be 1.125”).
Dillon dies (testing was using lee dies) would that make this much difference?
Loaded it to 6.4 gn on my Dillon, it shot well enough, (never had good results from hunters supply).
Nominal leading, hunter supply leads pretty bad at lower charge weights.
Broke out the labradar and to my surprise the velocity was way up there, on the order of 1220fps, (LEE has it closer to 1124fps for max so my load should have been less).
ES & SD was below 10, I’ll look at the saved file and get the recorded numbers if anyone is interested.
I knew this would be at the top end, but this has me concerned that it is too hot, like beyond +p+.
I stopped shooting this load when I saw the high velocity however, I had already fired several prior to getting the labradar. Over a hundred.
When I looked at the brass it looked like other +p factory loads after being fired, hence my willingness to fire that many rounds. Factory loads like Underwood & Speer, +p but should not be dangerous for a modern fire arm rated for +p ammo.
Did I just get very, VERY lucky or am I being paranoid?
The reason for this load was to match my defense ammo in POI & recoil.
I have plans on pulling the remaining rounds & salvaging what I can but have not gotten to it yet.
HS-6 performs best at the high end of the load data. It gets dirty at the lower powder charge weights. I think the CZ can easily handle it. If it shoots well, I would just keep shooting them, unless you are running a light set of springs.
I use that Lee 125 rn boolit over 6 grains and get about 1100 fps.
What OAL are you using?
Mine were 1.13 on average none were shorter than the load data from lee (1.125).
1100 FPS is where I thought this load should have been.
Could the tight tolerances of the CZ be contributing to the high velocity?
If so what other model pistol would be a good candidate for testing, or should I just call this a loss and try to salvage what I can?
Regarding the pistols it is a stock 75BD with less than 1000 rounds.
So it is still fairly new with the factory tolerances.
I have shot thousands of 9mm with 6 grains HS-6 and 155gr 38 super bullet. In my Mac 10-9 with the suppressor on. It is Hollywood quiet, bolt noise and thump at the backstop.
yup , 5.8-6 grains hs6 ive used with two Lyman dies and the mp 359-125hp, using clip on wheel weight with a bit of tin added, lubesized with carnauba red at .356 in g22 with storm lake 9mm barrel
A bit off topic, but in 158gr 357 magnum, I really like HS6

Hs-6 works well in the 9mm luger with my 125 gr lead bullet. Wspm . Using Speer starting loads. https://www.speer.com/reloading/handgun-data.html
9mm Luger is NOT low pressure @ 35,000 PSI.
