M=S, I only shot 2 whitetail's with this gun,being a handloader I'am all ways interested in bullet preformence.I shot both at about 100yds,one through both sholders and the other through both lungs.In the woods with leaves all over ,no chance to recover bullet.Both exi t wounds about the size of a soft ball.On the sholder shot it actualy rolled the medium sized buck up hill''''I never seam to be able to use the same gun, eather the buff classic T/C in 45/70 or a 7mag As for as the 458 mag,unless pa. stocks cape bufflo i don't think i will be able to find that 405gr in a whitetail.I am going to give the wet phone books a try someday.
