USARB rules prohibit electronics in the airgun for all classes except unlimited"spysir""american extreme benchrest" is a one of a kind event that does not follow standard BR rules ( in some classes you could shoot standard rules but it's not sanctioned BR) which makes it something totally different to look at. If you want to see who/what is winning in "competition " look at sanctioned events, BR, FT, 10m as the "american extreme benchrest" once a year event is much more of a fun shoot/promotional event than any standard competition which might draw slightly different gear and shooters.
