We shoot 25m and 40m benchrest springers in our little club, I'm not sure whether using a beanbag is technically benchrest....but our rules say only one support can be used, ie; Beanbag, bipod (When using a pcp), ricebag, cushion etc whatever...but one rest only. We often have scores of 97/98 ex 100, this is with an 8mm bullseye at those distances...fun fun fun.
