Oh and some comments for a shotshell newbie about hulls.
Far more pronounced are variations in hull volume than when loading centerfire brass.
My advice is to focus on only one type/brand of hull, a one piece and without a separate internal base wad.
If you use mixed volume cases some won't crimp properly and you can't transfer one load to a different hull without correct length shot wads and further with low volume powders and low internal base wads the primer can protrude almost beyond the powder and give unreliable powder ignition....very embarrassing when in front of shooters at a competition shootoff or such. Don't ask ! Some lessons are hard learned.
Medium length brass base is a good allrounder unless you're pushing for high power/velocity loads which a newbie should work towards and not start with.
IME 8 fold crimps have lasted best and don't have fold alignment issues with the crimp starter and it also pays to load in warm conditions to have the crimps last longer.
