The 100gr Nosler Partition with IMR7828SSC with a mag Primer (you haven't mentioned primer type) would be an interesting combination for your rifle. I am currently using the last pound of IMR7828 that has worked well with my sons Model 70 Winchester I rebarreled to 25/06 a few years ago.. This will be a at or near 90% loading for a min charge of 53gr, compressed charge if you use the max charge of 57.3gr. IMR7828 is a excellent powder for 25/06, it will generate high velocity along with small groups in the 243Win too.. William
