I'm getting a Lee 475 cal 325 gr GC mold for a plinking bullet. I expect the bullet to drop at 330 to 340 grs with WW's. I'd like to develope a 1,000 to 1,100 fps plinking load for this bullet. So far, the only data I've found is with Tite Group. I was hoping to work up a load with WW 231. Anybody have any suggestions on starting loads?

You might try the guy on this forum with the user name of (475/480 ) he has helped me with data in the passed.

Hoeram :D
