Hello all, I am getting ready to start collecting parts for a new 7mm build. I am trying to decide which 7mm Cartridge to build. I am leaning towards the 7mm-300 Weatherby. My gunsmith here in town just built a 7mm-300Weatherby and it is an awesome shooter and performes very well. He is using 140grn Ballistic Tips and 162grn A-Max out of his rifle.
What 7mm Cartridge do you think would be best. The 7mm-300 Weatherby seems to have a little bit more velocity potential. My goal is to shoot bullets from 140 to 180grns. I would like to get your input on this matter. I am going to order my barrel first, so I am going to order a 30" 1-9 twist Krieger. Would the 1-9 twist be the right twist for the 140 and 10grn bullets?
What would the velocity potential be with the 140grn and 162grn bullets. I am thinking with a 30" barrel I could push the 140's at over 3600fps and the 162's at 3350 to 3400fps. I would aprreciate any input on this build and what 7mm cartridge you think would be best.
