Am I correct that a 32 ACP uses a 30 caliber bullet, and that it's the same round as 7.65 Browning?

I had the craziest idea (oh no, here he goes again) of trying to do subsonic loads with more power by using 30 cal rifle bullets. Figure maybe use slow burning powders to keep pressure down, and give just enough to cycle in a semi auto pistol, or maybe a carbine based on a submachinegun with some of its parts?

Let the beatings begin...

GunGeek made me aware of a 32 S&W that I didn't think of. Maybe it would be better since its guns are manually operated?

yes the 32 uses a 309 dia bullet which is the same bullet used in the 7.62x25mm

I read 0.3125 on www.reloadbench.com . Suppose 0.311" bullets for 7.62x39mm would make a good subsonic round?

Maybe the CZ-52 in 7.62x25mm would be a better choice to use them in than a 32 ACP gun.

you may want to run this buy the lab techs at one of the powder companies and they can give you numbers which would be safe for testing

Is it Sierra who will give you load data for a cartridge by phone, no matter whose bullets you use?

 

[Shaun]

Sierra is Excellent but you can also call Alliant & Accurate depending on what you are trying to do -- I have actually had Alliant test loads for me and they give all the ballistic data within a few days if it is feasible.

That's great, have any contact info?

 

[Shaun]

just go to the websites that's what I use to call them
