components help!
 

OK heres the deal. I am loading up shotshells for my 45 long colt. I need various sizes of shot to test. I would like to get some #12 and #10 shot (other sizes I can rob shells off the shelf for). I cannot find them hardly anywhere except ballistic products. Problem is I DO NOT NEED 10lbs of shot for testing! sheesh. even if I knew for sure these were going to be my choice do you know how long it would take for me to go through 10lbs of shot loading shotshells for a 45?!?!?!?!!

Any help or advice would be appreciated.
