I came up with a pretty good box to protect your Chrono. It's useless when it's at home. Ya i stuck a Blue MMP sabot right thru the screen.
I did get the numbers with the 250grn Lehigh bullet. I sent them off to Lehigh to figure the BC. I dont have a program to figure it out here. The chrono's were 100yds exactly apart. I will post the BC'S as soon as i get them.
