Not sure this is the right place to post this, but...
So I can't get RL 15 and one powder I am considering as a substitute is Norma 203b. Could anyone run a quickload simulation and tell me what Min and max loads and velocities and pressures would be?
I am running a 260 gf accubond out of a 25" barrel 375 h&h, using federal brass and Winchester magnum primers.
I also heard that QL will offer suggestions on other substitute powders...ie something like RL15?
Thanks!
