Like said it is possible but not a good idea. Inevitably over pressure loads like that find their way into a weaker .38 Special revolver which cm be very dangerous.
Why do you ask? Maybe we have another way of helping you.
Edit: you don't just add more powder, you would normally need to use a slower powder too.
Good Morning Everyone,
thank you for all these answers posted overnight !
So I have to clear that I am not planning to start reloading anytime soon, nor do I have any equipment for it.
But it definitely seems like interesting idea down the road one day - some people say they even find it relaxing ( I find my gun cleaning and polishing relaxing too, if I am not in the time crunch).
I am asking this just out of curiosity and learning new interesting facts.
For example, all these years I assumed that 38 SPL is more powerful than 9mm, just by visually looking at the case ( "longer shell- more gun powder inside")
Then someone here told me few weeks ago that 38 SPL started off with different powders long time ago, hence the longer case , AND that cases are NOT packed up with gun powder to the max of the case volume.
*silly me*
Back to my original question: I was thinking that since there is still empty space left in 38 SPL case, just by adding more gun powder inside, you can reach more bullet velocity and get same ballistic results as with 357.
Then, I just learned here that with 357 you should really use slower-burning powder - it is a whole little science, I guess
I totally get safety issue, too - 357 does not fit 38 SPL revolver so it prevents it from being blown up with higher pressures that it was not designed to withstand.
(I do have a 357 revolver and none in 38 SPL only)
Another question for you guys - save me internet search:
let's say you are using same type of 115 grain bullet, how much grains of powder you will use to load standard 9MM, standard 38 SPL and standard 357 ?
what muzzle velocities will each one of those loads typically create with 115 grain bullets?
