[QUOTE="Grizzman47, post: 3027923, member: 125904"] Plugging in 2.820" OAL and 50.88 grains of water, 1.910" case length and keeping the powder charge at 42.5 nets 1.190 ms of barrel time and still a bit over max. With a long 26" barrel, the nodes are going to be quite widely spaced. To be within .0005 ms of the next higher whole node requires a drop to 39.0 grains and an OAL of 2.810 to achieve at 2884 fps and less than 49,000 psi. The 4 and a half node requires 40.6 grains at an overall length of 2.800", gets approximately 2974 fps, and is 88% of maximum pressure. If the half node works out, this wouldn't be too hard on the barrel. [/QUOTE]
