I actually was making little shot capsules out of wax paper wrapped around a brass welding rod that is about 20 cal.; it fits into the shot shell snug with the paper wrap and the cap stays in when I remove the rod. I drop in the shot a few at a time til wt. is close to factory full case; with my 7 1/2 shot, it's only 8. A smaller cap put in backwards for the top and lightly tamped in place completes it. It's time consuming, but if it's raining and you got alot of empty hulls; it goes by fast and I've reloaded them several times. Mine came with 2 boxes and that lasted only a week for me and after my 1st order, I was glad I saved all the cases, and yes 25lbs will last several lifetimes. You can also count the shot in a new shell, since your's is also 9 shot. Less would be less effective and I would be very careful going much over as too much wt may damage the action, you might try 1 or 2 extra as 9's are lighter than 7 1/2.
