828U cast adjustment

[DEE]

I've shimmed my 828U to -6 (LH shooter) but still need some additional cast on. Does anyone know how to get more cast on than the -6 shown in the mannual?

[remarkable]

Some fitters will increase the hole size in the drop shim plate which will increase the movement from right to left.  With that being said it is then difficult to fit the drop shim behing the stock.  Some fitters will add another shim to this stack, remembering most of these fitters do not care what the gun looks like at that point, they are only concerned with the fit not the appearance.

Personally I would not recomend this approach.
