For quite a number of years I killed all my deer and moose with one sinlge rifle, that being my 284win, loaded with 139gr. Hornady BTSP's.

In more recent years I've used with good effect, the following
25'06 (100gr. Part or TSX)
270WSM (130gr. Accubond)
358Win (200gr. Hornady SP)
7mm-08 (120gr. TSX)
280AI (150gr. Ballistic Tip)
300WSM (165gr. Interbond)

Just remember.
You cant have SLAUGHTER,
without LAUGHTER
