I have copied and pasted the applicable part of the Williamsport rules below. I also checked the the NBRSA rules and for long range there is no stock width maximum.

49.0 In the Heavy Gun class there are no restrictions concerning the type of sights permitted.

51.0 There are no restrictions as to the width of the rifle's buttstock.
52.0 Shoots shall be fired with sand bag front rests which may be supported on a pedestal which may not co-act with the sand bag to restrain recoil or form a return to battery guiding means.
