Ive only loaded for a few different calibers so I havent tried many different powders but it looks like IMR4064 is among the bulkiest judging by dipper size. vs grains.

For my 7 RM I would like to use as light a charge, while filling up the case as much as possible. Im guessing this may cut down recoil while getting as more shots per lbs? Is this correct? Do you have a better powder suggestion?

I have a bunch of speer HC 160s leftover and would like to use those but I dont see a load for it w/ 4064 in my book. anyone have a load?
