I have several hundred 150gr. SWC boolits sized to .356 , I’m looking for load data for 9mm using this and possibly heavier . Anyone have any experience with heavy bullets in 9mm? Will be using these in an S&W revolver. Thanks in advance for any info !
What powders do you have available?
I have been playing with some lee 158gr tl found vectan A1 with w.s.p.primer from my Ruger p89 in Winchester case at col 1.125 692 FPS 168ft/lb es of 23 and sd of 10 was enough to cycle the gun reliably 2.5gr was almost the same but 735 average I worked up higher but don’t have any good data on them as my crony was being finicky that day and dose not like the indoor range
Power Pistol is your friend here. I load the Lee 150RN over 4.2gr. I have found the slower powders make the velocity to stabilize the heavy 9s a lot better, at the cost of the the powder puff recoil impulse you get with light charges of fast powder. Not sure what the twist is in your wheel gun, but that might also play a factor in stabilizing the heavies. My auto pistols are mostly 1:10.
You could use data from the Lyman cast book for 147gr and go from there. I shoot that boolit in my 9mm semi autos.
SWCs may not be optimal for heavy 9mm unless you seat them quite deep.
Been shooting RNs/LRFNs & TCs for sub loads in autoloaders from 150g to 160g using TG & Bullseye
Deep seating SWC .38 bullets in 9mm brass so that they will chamber may dangerously spike pressure.
Do not seat bullets deeper than specified in published, lab-tested data.
If you have an S&W 9mm revolver, you will probably need to size the bullets smaller to enter the cylinder throats in order to maintain correct, safe overall cartridge length.
I just noticed the part about using them in a revolver.
I have a S&W 929. If your revolver is like mine, you can seat the boolits much longer than you can for a semi-auto. You have no magazine constraints on the length.
This allows you to be able to use a bit more powder since the case isn't full of boolit.
The cylinder on my revolver has no ledge at the front of the chamber for the case to headspace on. That part is taken care of by the moon clips. There is a smooth transition from the case to the front of the cylinder. You can play with light loads since you don't use the cartridge power to work a slide.
You can literally use any nose shape you want since feeding is not an issue at all.
As far as powder, use the same powders as you would for a 147 grain boolit in any 9mm cartridge. Begin with the starting load and do not seat any more boolit inside the case than the ones described in the manuals.
The starting loads for 147 grain boolits make a nice, soft shooting cartridge for a revolver.

Thank you all for your response and the info , its greatly appreciated!
Which S&W revolver are you using?
S&W model 610 , I have four , five , and six inch barrel. I love my 1911's but i really have a thing for wheel guns !
Odd. I thought the 610 was chambered in 10mm.
You are very right , sorry I confused myself I’m working on my 610. It is a 5in. Model 986 . My wife keeps telling me that’s one of the signs I’m getting older , I can’t remember the others !
I can relate to that. Some days I can't remember my own name.
What's in a name....?Quote:

3.6 Grain of N340 is my go to load for my S&W 929 with any bullet from 140 grains to 158 grains. I use 9x21 brass and seat the bullet out further than anything that would function in a 9x19 semi auto. N340 meters very consistent and is clean burning even with light loads. 3.6 grains in a 9mm is on the light end of the spectrum even for a 150 grain bullet and is the max load for a 165 grain copper plated X-Treme bullet in a 9x19 case.
