If you were to chart my caliber perferences (in power) since the beginning it would start with 357 with a rise through the 44 mag and beyond and then drop a little when I finally bought a 41 mag only to rise again with the 500WE and now drop to the 32`s... Much of North Americas game can be cleanly taken with a 41 and the correct bullet... The 327 Federal is much the same to me except for the size of the animals with which to use it on... Now with Rich Mann taking a large body whitetail using his 5 1/2 Ruger loaded with a 130gr cast at 1425 MV from his SA makes me take a diffrent view of the cartridge.. I don`t know how far he had to track the deer or details of the hunt but its still impressive.... Time will telll...
