What would the result be of using buck or bird shot in a rifled slug barrel? Let's say I'm not too concerned of the rifling being destroyed. How would the shot pattern be effected? Would the rifling create enough of a void that there would be significant pressure loss?

In a totally different thread many moons ago I asked about shooting the .22 cal shot shells in a .22 cal rifle. (They actually used to make .22 cal shotguns once upon a time!) The resounding reply was it would not have any accuracy and would produce a doughnut shaped pattern with a void of shot in the center of the pattern. I suspect you may find similar in this scenario.
I suspect if your shooting lead it will have little effect on the rifling.
Hope that helps!
Might be interesting to see a pattern board from a shot at say 30 yards???

They still make it. I buy CCI .22 shot shells all the time. I use them on mice inside my cottage, no damage to floors or walls. The shells I used to buy as a kid were 22 mag brass filled with metal flake and crimped shut. The ones I get now by CCI have what looks like a pill capsule at the end and are filled with #9 lead shot. The older ones were more indoor friendly.
The shot "donuts" because the whole shot cup is imparted with a spin, similar to the rotation on the bullet. When the shot cup clears the end of the barrel, the shot is spun out in all directions (except straight).
The effect was less pronounced in the age before shot cups but, even then, patterns were negatively affected. In the absence of a shot cup, the shot on the outter edge of the shot column gets flat-sided by the rifling grooves. The entire shot column spins and the shot is sprayed out in a vortex as it leaves the barrel. The difference between with and without a shot cup is that, without the shot cup, there are "fliers" caused by spinning the shot column and other fliers caused by the poor aerodynamics of flat-sided shot. Another difference is that, without a shot cup, a few pellets might actually hit the target.

Smart man.
"...shot is spun out in all directions (except straight)..." The shot string goes straight, but it's in a spiral. vpsalin's picture is the perfect example of what happens.
If I could only get a doughnut that big. Mmmm, doughnuts. snicker.

For very close shots #8 shot will work for grouse if that's your plan. The new CCI bird shot with the blue plastic does not leave a considerable ring like the old crimped breass ones. But #12 shot just pisses off rats and won't break a skeet target even though you can hear the bb's hitting it. I tried various buck loads up to ooobuck from a slug barrel. Didn't hurt the barrel but a 250lb bear at 7 yards may be untouched
