Re: 7mm Rem mag and Berger bullets
Hey Shawn, according to my EX-BAL program using the 180vld zeroed at 100yds and coming up 10moa to zero at 570yds the velocity is 2956. That is based on 1000 feet elevation, 59 degrees, and 78% humidity. I believe you can use the G7 program on this forum to validate it there too. I'm shooting 72grs H1000 to get 3035fps out of my 7mag 26" barrel, 215m primer. Shoots lights out too. At 72.5grs of Retumbo I was getting 3110 and awesome groups out to 500yds, but the ES killed me at the longer ranges. Right now I'm working on breaking in a 28" Broughton 5c with the 180's out of a 7mm-375Ruger and getting 3153fps with 73.5grs H1000, 215m.
