Howdy y'all, its been a while, life got busy and only recently got back into casting lead again.
I have some pure lead 7/8 oz Lee Key Drive and Lee .690 Cal Round ball (LRB) that I cast up and cant really find a lot of load data for them.. Rifle and pistol reloading I have experience with but shotgun is a little different. So far, Ive had good luck taking bird shot shells cutting open the crimp, dumping the lead bird shot and replacing it with the slugs and LRBs then roll crimping it down. These so far have worked "okay" out of my H&R with a rifled barrel... meaning they are not showing any signs of pressure and group about the size of my fist at 25 yards.
But I'd like to find some places to get load data so reload them without having to keep cutting open bird shot shell.
I currently have a copy of the Lyman 5th edition but there is no mention of these projectiles listed. Is it safe to sub out the published payload for an equal weight of another type as long as it ends up the same length or is that a no-no in shot shells? The Shells I have I don't see listed in the book too much either; they are the Win Super-X that were factory loaded with slugs before getting shot.
