I could just dump the powder and use another, which would be a good one? I dont understand what's hard about the question! Let me put it another way, I have primed cases, I have 124gr bullets, I'm missing the powder, what powder does anyone recommend for these bullets that will also work good with say..115gr FMJ?

If I can pull them and get 115gr FMJ then I'll trade but havent found anyone to do it but the original question was whats a good powder?

I got a lot of 9mm +p 124 REM Golden Saber a freind gave me but I dont want to shoot it through my Browning HP. I was thinking of pulling the bullet, weighing the charges and then taking off 1-2 gains of powder and reseating. I could just dump the powder and use another, which would be a good one? I just want something to shoot, not looking to make a power factor, just want it to work. Ideas? I've heard about changing the recoil spring and using a buffer but the C&S shop says not to shoot +p!
