Need a 38 cowboy load

Yes!
The danger is Stuck bullets in the bore.

If you just gotta do it, 4.0 is the minumum recommended charge.

That will give you:
725 FPS - 9,000 CUP.

Below that velocity & pressure, stuck bullets are very possible in guns with wide B/C gap.

The danger would be sticking a bullet in the barrel and then firing another round behind it. This usually bulges the barrel to some degree.

Shoot them one at a time and pay particular attention to whether or not the bullet clears the barrel. If it doesn't, then use a brass rod to tap it back out of the barrel. If it locks up the cylinder, then drive it back into the cylinder so you can get the round out of the chamber.

Hope this helps.
