[QUOTE="Derek M., post: 216950, member: 2693"] Appears to be a good starting point but if your bullet is at or into the lands, 77 or 78 gr would be a little safer. 3000 fps is of course a good goal, but the Retumbo may have different nodes at even higher velocities that produce equal accuracy. You just don't know until you try it. I always recommend new load development on warmer days if possible so you can find what top end powder charges will be with the bullet seated at or into the lands. Not sure why you want to go from Norma brass to Remington. Isn't that a step in the wrong direction? [/QUOTE]
