I need more cast off on my 300 ultima 20. Are addition shims available or are there other options?

When I wanted more angle, I took my largest shim plate and some 2" metal tape.
Calculate your trigonometry to get the additional angle desired.
Lay a stairstep of tape. The stuff is very thin.
Then lay one layer crosswise, like carpeting the stairs. Burnish flat. Trim excess tape off with razor knife.
Take into account your stock bolt, as you can have more cast than the stock bolt can handle.
Cost is ... 50 cents worth of tape at most. I used copper tape because I had a roll around from making electric guitars. The aluminum stuff is cheaper. Home depot.

Whatever shim you're using for cast, select the one with the greatest angle. Then increase the angle by adding a stair-step of tape, making a ramp. The cast shim is between the receiver and the stock.
