Good choice in your Vanguard 7mm Rem mag. Like I posted earlier, my foul weather back-up elk rifle is a 7mm Rem mag with 160 grain Nosler Accubond bullets. That is also the rifle and bullets that I am taking to Quebec next week for a caribou hunt.
In the mid 80s I took a friend of mine moose hunting. One bullet from his 7mm Rem mag put both of our names in the B&C record book with (at that time) the 4th largest Shiras moose ever shot in Montana.
