Has anybody used RL17 for their 348, or know if it would work and where to start? 250 gr bullets. thank you in advance.

Have not, but its burning rate is close to 4831, 4350, and H414, I think it a bit slower so I see no reason for it not to work..

I have a few pounds of RL-17 for my 9.3x62 so maybe I will try to work up a .348 load..Not sure where to start however, but I'll try and figure that out. Someone on here may have a starting load, that would sure save me some time and misery!!
