What cartrage are you guys shooting to 1600? I Have never been able to get any degree of accuracy once it hits that trans-sonic range.
.300 RUM, shooting the 208gr A-Max.
what speed you getting out of that. Running the numbers with a 210 vld @3000fps I'm seeing the bullet go sub sonic around 1400yards unless your up high and pressure is low. Even at 3100fps it's down to 1300fps +/- at 1450yards. I could see getting out to 1600 if your up high with pressure around 24.50 inHG.
3100FPS, 93.5gr of Retumbo.
