I reloaded shotshells up till about 20 years ago when I didnt have time to fool with it much I gave all my shotshell stuff to my uncle (and just loaded rifle and pistol)and if I did shoot a shotgun much just got a few shells from him. Now I seem to find myself getting ready to start back up again as my sons are getting into skeet shooting. I will be loading 12,20,28 and I am noticing all the loads that list hull brands, I know hulls are different as far as how they will crimp (some better than others) but I am wandering does it really make a difference as to the type powder and wad you put in them? I see thousands of different combinations. I plan to use unique powder for the 12 and 28 # 6, 7.5,9 shot for example and we have lots of different brand hulls that they have collected from dove shoots and stuff, I am just loading for kids shooting for fun, will the different brand hulls and wads be a saftey issue a performance issue or no issue at all? I know from loading rifle and pistol rounds all these years things have changed alot but how different can a 2 3/4 12 ga. hull be from one to the next.
