I am new at shot shell reloading anmd have a million questions. I have been reloading 12 gauge using:winAA hulls,waa12 wad,win209 primers,7 1/2 shot,clays at 18.5 grains,or green dot at 20.5 grains.loading 1 1/8 oz.After I load the powder,it looks like there are too many shot in there to close the crimp.It tens to buckle the hull a little. I have my wad pressure set at 55 pounds. Someone tod me I could use a rem figure 8 wad instead and have a little more room or go to a rem sp hull. Can I do this safely? thanks. sj
