Am I correct in guessing that there are basically 2 different types of hulls, tapered and straight base wads? So would load data for one tapered hull work for another tapered hull of a different brand, and the same for straight base wads of different brands?
Basically I have a good amount of Winchester universal, newer AA, and Remington gun club, all of which have tapered base wads. Could I use the same load data for all of them?
I also have a boatload of federal bulk hulls, which are short base wad, and I can’t find data for this specific hull. Does it interchange with something like a gold medal for load data?
Also, does the height of the brass really make any difference for the load? For example, can I load something like buckshot in a low brass hull?
Thanks for any input.
