Using Buford on heifers

Has anyone used Buford on heifers? Results?  His birth weight is listed in the 50s but that is incredibly low and could be considered an anomaly.  Thoughts?

Heifers will be large commercial Brangus heifers. 

I used Buford on a Pump Daddy heifer to calve last year as a two year old.  She is a smaller framed heifer but she had a nice solid red heifer that probably weighed around 65 lbs on her own.  I sold the heifer as a replacement heifer and the Pump Daddy bred back for another calf.  That is just one calf but I bet you will be okay using Buford on the type heifers you are describing.
