I took my first whack at reloading some paper hulls over the weekend for my Lefever. 16ga. Federal Monark purple paper, with paper basewad (I found a couple dozen once-fired ones at the trap range). 1oz., W209, 23grs. Longshot, sg16 wad, about 7k psi and 1250 fps. What most impressed me was the crimp. The waxy paper makes an incredible tightly sealed crimp, much better than the plastic Federals I've been using. Best yet, they have less internal capacity than the Fed plastic, so I don't have to add puffed wheat to fill up space. Really a wonderful, tight load, with no shot "rattle" going on inside.
Has anyone ordered any of the paper hulls from Grafs? I think I'm definitely a paper convert.
