This study presents the results of a measurement of the B cross section in conjunction with Fermilab experiment E772. In this fixed-target experiment an 800 GeV proton beam interacted with a thick copper absorber. The trigger was set to detect muon multiplets emerging from the dump. Production rates and acceptances of trimuon and like-sign dimuon events were used to calculate the B cross section on the 1-4 GeV ρτ range. Experimental acceptances were found to be highly model-dependent and these model uncertainties were explored. The dimuon data was found to support a 350 nb upper limit for σ[subββ] with a large model uncertainty of order 10.
