You did good. I haven’t used that but data from a book is where you want to start.
As far as components that work for for all…..it is possible but hear this out. I decided against it because I want to be able to tell my slugs and buck apart at first glance, that way it is just one more step in place so I don’t mix them up.
So although I don’t recommend one thing for both I have mine narrowed down to two type hulls , two powders one primer and three different wads……as far as going broke it won’t happen , especially if you have a way to cast the lead. Casting aside, all my hulls were scrounged from two gun clubs and the woods, free. The powder cost about 16 to 20 bucks a pound, roughly enough for 175 hot slug loads or 290 mid power 00 buck. The primers are Winchester 209 , they are about 30 bucks for a thousand. Wads are less than 10 bucks for 500.
As far as data, I am no longer using published data for only one reason. The cast stuff doesn’t fit in the hull the same as the factory shot. So I had to start to figure out loads that would let me fit all the components together and still have a good patterning load. For the slugs, I also am using “my” load based off of published data . Reason for that is I needed more room in the hull so I could put a hard nitro card under the slug to separate the slug from wad , much more accurate. So you see I can’t really just hand out my particular data unless you are using the same stuff as me and having the same problems as me, shooting from the same gun as me…….I think if you guys start reading data , play with loading and use factory made shot and slugs you can get it narrowed down and have great success using published data to a tee. I will help you get through anyway I can.
For now all my slugs are going into Remington gun club/premier sts/nitro 27(all the same construction hull) using Blue Dot and all my buck is going into Federal Gold Medal and top gun, not the same construction but I carefully have made a load that works in both well using Herco powder.
