i have never bedded my mini stock for accuracy. at this point, it shoots well enough that i am pretty afraid to mess with it. but i know bedding as a proven mod, so i think about it now & then.
i purchased a SS 580 mini. it came in a poly stock. imo, this stock always seemed to have a considerable amount of "play" or looseness to it. my gun came out of the stock very easily for cleaning.
i got older style wood stock cause i found a deal and disliked the look and feel of the ruger poly stock. upon switching them out, the first i discovered was how hard it was to fit into the wood stock. i really had to put some weight and muscle on it to snap in the trigger assembly. it is a tight fit. it has gotten a little easier with use.
has anyone noticed an increase/decrease in accuracy between the two stocks? i think the wood stock being such a tight fit might be an advantage. however, i don't know if this is the experience with all wood stocks.
just thinking out loud....
