H20BUG - I think you are correct. But, I plan on using dippers. I hate to see anything go to waste and since I'm only looking to shoot cans and carp out to 25 yards it does not need to be as accurate as my hunting loads.

I also found a few pounds of 4756 too. I think I'll go with a starting of X700 at 4.7 gr and 7.0 4756. According to the charts both should give me about 800fps w/ 180 - 200 gr. bullets.

Thanks,
Bill
