Question for you reloading gurus:
I picked up some bulk Missouri Bullet Company "Pinbusters!" for a steel plate/bowling pin load. I did not realize there was a shortage of reloading data on 250gr bullets and am starting to second-guess my wisdom in buying these. I've reloaded quite a bit with 230gr and 185gr, but never with 250gr. I've also read that these are harder on the brass (due to deeper seating).
Brass: Misc (mostly Winchester and Federal)
Powder: Win231
Primer: Winchester Large Pistol
So far what I have found via experiments and Quickload:
Avg boolet length: 0.661
Cartridge OAL: 1.175 (puts the neck of the case right at the top taper of the bullet).
Quickload says 4.0gr of Win231 should be just below the caution zone (15,000 PSI) and 694 FPS. I'd probably start with 3.8 and work up.
Anyone have any good info, advice, etc? Would it make more sense to just send these back (and have to eat the shipping) and get 230gr?
