There have not been any problems so far. The paper was cut to fit, glued and held on by a rubber band for 24hrs before use.That's good to know because I will be doing 7saum as well, with other 30cal and .338 cases. The loctite doesn't melt or get too hot from the torch? You should post a picture of your modified wheel.
Were you using their WSSM wheel set for your SAUM? I had to use them for my 6.5 PRC. It works great for me.
Yes, the case would drop fine but just set there, never would rotate.
I tried cleaning the wheel, brass was clean (no lube) after tumble.
