I'm currently working on a load for my 264 Winchester Magnum. The load is 65 grains of IMR 7828 behind 140 grain XLC. My velocities have averaged 3050 fps. groups can be covered with a nickle at 110 meters. Question is that i'm only one grain above mim load. The barnes manuel list mim at
64 grains velocity 2905 Max 69.0 grains velocity 3132.
by increasing to 66 grains could I expect another 155 fps or lose fps? Right now i have no pressure signs but how much is too much?
It is not what you use, but where you hit em.
