[QUOTE="Deleted member 46119, post: 1027206"] First, I must say I'm very impressed :cool::cool:. I'm not going to make one. Second thing to say is ouch. Down to brass tac drivers. If you have a 32" barrel, IMO your goal of 2400fps seems very doable. I have not cut my Jamison brass in half to measure but we are lead to believe it will take 65k psi. I ran the numbers in QL with a seating depth just shy of seating bullet body below the shoulder. COAL: 4.730 Usable capacity: ~137grms Powder: Reloader-17 Charge: 125grms Extimated PSI: 61k Estimaed MV: 2400fps Energy at the muzzle: ~9500 Recoil: Enough to launch you into the next county Drop at 1750 yards: ~1350", ~75MAO Energy and fps at 1750 yards: ~2400'lb at ~1200fps Subsonic distance: ~2000yards Energy at 2000yards: ~2000'lb So there you go. More than one person (you and me) thinks you can get there from here. Oh my god cool and show pics please. [/QUOTE]
