Hi all, I recently got into shotshell reloading and made up a bunch of boxes for trap shooting. The load I am using is win AA shells, win209 primer, winAA wad and 17.0 grains of 700x. I weighed my charged from my loader to be sure I was getting the proper weight when I started loading and I was getting 16.7, 16.8 ect. However after getting about 3 boxes done I decided to weigh it again and was getting lighter charges of powder anywhere from 16.0- 16.5. My question is will these loads still be safe to shoot? They are about 1 grain lighter than the reloading manual calls for. I have the problem corrected now but want to make sure I will be ok shooting these. Thanks!
