My 270gr 44cal cast boolit is a SAECO#44439 240gr Keith type SWC

Gas Check design... Mine weighs 270gr because the gas check part

of mold was eliminated. lt gives the boolit added weight at the

base. Called ''beagling''- This is a common practice done to GC

molds. l bought the mold 'used' off the net. l suspect it was a

custom factory order because there are no additional machine marks

where the GC shoulder or step was originally. The box also says

'custom'. Many shooters like Elmer Keith preferred the wadcutter

shoulder of this design.. Cuts paper well and meat even better,,
