Wayne, if you go to page 2 on this forum you'll find two threads on reloading - one for 2 5/8 and one for 2 7/8 shells. I was useing a 6 point crimp - don't believe a 8 point is made. A roll crimp will have less pressure than a star crimp. I bought from Ballistic Products the Remington 10ga hulls and cut them to 2 5/8. Get a Mec 600jr set up for 10ga with their " short kit ". The short kit will make the shell go up into the final crimp station more so you'll get a crimp that isn't bulged. They fit in the gun MUCH better. Fiber wads from
www.circlefly.com usually will give a lower pressure than plastic wads and I feel can be used safely to adjust wad column height. Use only fiber wads when reloading black powder unless you want a major headache cleaning plastic out of the barrel. Hope this helps.
