I know it's gonna be slow, but I'm only fireforming this time around. I've got almost 3 lbs of 33 that I have no use for and figured it'd work great for forming brass.Did you mean rl 23?
Rl 33 will be way to slow. I crammed 67.3 grains of rl33 with drop tube under a 150 lrab and got a meager 2787 fps. Same amount under 170 Berger for 2838 fps.
