[QUOTE="RT2506, post: 1770470, member: 10178"] You never stated what charge or bullet weight you are using but I assume 140 from the velocity stated. Yes you guessed it you don't have enough barrel. I learned over the years with the 264 Win mag that it needs at least 26" barrel to do it's thing. Drop back to 24" and it becomes a fire breathing 6.5x55 but increase the length to about 28" and it will become a rocket ship. You might get a little more velocity with a faster powder but it will not be much. In my 40 years of hand loading experience usually the powder that gives the best velocity and accuracy in a longer barrel will still be the best in shorter barrels. My buddy and I worked with the 260 Rem. when Remington brought it out. The rifle was a stainless synthetic 700 with 24" barrel. There was no load data out yet and we could not even find any ammo or cases so we went wildcatting and ended up making cases out of 243 Win and discovered H4350 was THE powder for 120 and 140 gr bullets. We were doing crop damage control in those days and we killed 50 deer that year with that rifle from close in to a touch over 500 yards and had only one take a step after receiving a 120 or 140 Sierra SP bullet. That one only took three jumps before doing down. My buddy traded off that rifle to a fellow for his grandson by the next year to move on to fooling with something else.
