I messed around with my MEC press today and think I want to try loading slugs, buckshot, and maybe some big RB. I have never loaded for shotgun but have had this press for about 5 years.
Lee has load data with their slugs, I understand hulls, wads, and primers shouldn't be interchanged which is fine because I have AA hulls, WAA12 wads, and Winchester primers, my question is the powder charge they list. 1oz with 36.0gr of Herco is the charge for this combo. Is that the end all be all load or is that a max to be worked up to?
Would anything need to be changed if I used a .69 RB?
I'm not doing anything serious with this just blasting stuff with smooth bore pumps and an Ithaca buckbuster.
