Looking to load for a 40 s&w carbine. I know that handgun loads work but I am wanting to get the full potential out of the gun. Do I use the slowest burning powder for a given bullet, or what do you guys use. Any loads, or suggestions will be appreciated.
Thanks
Factory handgun loads are what carbines are designed for!
Anything hotter than published reloading data, would be reckless and possibly cause serous injury if a Kboom were to occur. Pour as much powder in those cases as you wish, but please be considerat of innocent bystanders and touch them off alone in your own back yard.
