Hey there Val,
I wonder why you have found the 30/06 to be "too much gun" for deer.
Is it meat distruction?
I use a 300 win. Mag. on our Idaho Whitetails and never feel "over gunned."
I do however, use premium bullets in the form of Nosler 165gr. Partition, but from what I read, the "Interbond," a BONDED BULLET, should have almost as much integrity as the partition.
I do not feel under gunned with my .243 or the wife's 270, but choose to hunt almost entirely with one rifle which happens to be the 300 Win. Mag.
Will probably apply for a cow moose permit again this year, elk season is open for part of the whitetail season and a bear is always a possibility, so I am pretty much a one gun hunter.
Took two whitetails this past year, and as far as meat distruction, I am sold on the partition.
Have used the Partition for most of my hunting since one of the "old" pre interlock Hornadys came apart on me the Fall of 1968. I'm sure of that date, as I found the horns during a clean out of my shop this afternoon.
That was with a 243, 100gr Hornady and a Washington muley buck.
I do have Hornady interlock on the bench for .243, 270 and 30cal. but expect to keep using the Nosler Partition in my 300 as long as I can get or afford them.
Keep em coming!
