Skeet:
I have about 400 of the Federal Top Guns which I wanted to get started on, and then I planned on moving on to Federal plastic Gold Medals. After I had posted my question last night, I looked again at the manual, and it does mention about hull bulging, and offers several suggestions including using less dense powder, less shot, a shorter wad, etc., but all of the components I am using are the very ones prescribed for the loads I am working. Then it mentioned adjusting the wad pressure and adjusting the final crimp, as you suggest. I will give that a try tonight and see what happens. What I find especially puzzling is the inconsistency in that that some loads came out looking OK, when others had the bulges.

When you use the same or similar loads in the Federal shells it fills the case too much and, when you apply a crimp, it crushes them right above the brass. I have never liked Federal shells for reloading and still don't. However if you go to a plastic wad that is not so tall - say going from a Rem. RXP-20 to SP-20 - that usually seems to cure the problem, at least in my case.

I slit open one of the empty Top Guns and noticed the taper on the fiber base wad, and can see what you mean. I am using the prescribed wad for the load, however, but maybe making the adjustments as mentioned above may work for now. I have heard many good things about the Remington STSs, and after I get my feet wet with these cheaper Federals, I may go to the STSs.
Thank you both for very much for your input. Anyone else?
