[QUOTE="Carey Farmer, post: 3058273, member: 122715"] This is a great way to approach this question. I feel the same as Mikecr about muzzle blast. I hunted for many years with a 338 Winchester Magnum, 25" barrel. Then I bought a 300 Weatherby Magnum, 24" barrel. Couldn't believe the muzzle blast. Now when I build rifles chambered with big cases shooting slow powder like Retumbo or H1000, I put 32" barrels on them. That gets me good muzzle velocities with manageable muzzle blast. Around 10,000 psi muzzle pressure at bullet exit. With the same load in a 26" barrel, would get 150 fps less velocity and muzzle pressure would be 13,000 at bullet exit. [/QUOTE]
