[QUOTE="J E Custom, post: 1377782, member: 2736"] In my younger days, I contracted the speed disease like many other have. I decided that I wanted, A 140 grain 7 mm Bullet to go 3800 ft/sec. It was a good learning experience for sure. I managed to exceed the 3800 ft/sec. BUT I found the limitations of this folly and feel it is true for almost all cartridges. Different bullets have different limitations, based on Diameter, Weight, construction, Twist rate and powder used. I also have another Hot Rod in .224 that has exceeded 4600 ft/sec And found the same limiting factor, BULLETS. I am now down to only one bullet that is still accurate and wont destroy itself at these velocities that still has good accuracy. Aside from many other problems associated with excessive velocity, The bullets are the limiting factor because at some point it can lose all accuracy. I have had jacket separation at these velocities and tried the Mono Metal bullets to try and solve this problem, But accuracy still went away. So as to your question, I think that any twist, cartridge, bullet and caliber combination will be limited ultimately by the bullet it's self, not barrel life or money as long as we have the "NEED FOR SPEED" As stated, Accuracy is the one thing that decides how much velocity is enough, Nothing else. It doesn't matter how fast it is, if you cant hit anything with it. J E CUSTOM [/QUOTE]
