they will kill deer. just make sure the bullet is .001 or .002" oversized, or .309" or .310". i use a .311" 173gr Ranch Dog (12+/-BHN) in my 30-40 Krag. i use a .431" 280gr WFN GC (18BHN) in my 444 Marlin and 44 mag.

stay away from round nose cast bullets esp at 18BHN. it is like a pencil point wound channel. FN, LFN and WFN are the best. they tear up the lungs.

"Russia sucks."

Russian Admiral said, after the Moskva sank, "we have the world's worst navy but we aren't as bad as our army".
