8" @ 200 aint bad at all. Thats a, Put the sight on the back and let it go.
That is with a 100g charge, your showing 80. They look a lot stronger the the regular PB, they may hold up to the 100g charge, maybe even higher. Shoot some at 20 and 53 with 150g of powder and see what happens. They may stay together.
