Guys i have 500 of these and i'm getting ready to load them up for WY antelope out of an 18" Broughton-barrelled Savage Striker 243 WSSM. Anybody know the BC of the bullet? ...and what happened to it? Heard some rumors that it was coming apart out the barrel of some fast-steppers, and they were supposed to come out with a heavier jacketed 111 gr.? Anybody know the story?
