Thanks for all the info guys. It was the Shilen site that got me thinking about the 8mm Mag Jerry, I wanted something different but wanted to be able to do it myself on a Stevens/Savage action. I could go and buy a 300 Ultra Mag in a Remington SPS which would give me the longer reciever needed to complete this project but I just don't want to have to deal with having the work done by a gunsmith.
I am sure I will look at the Shilen site a few hundred more times and come up with something. Believe it or not I want a rifle that hits hard, extremely hard and is a little different than what everyone else is using. Currently I have a 6.5 swedish mauser for deer, and a Savage 99 308 which I use as a bush gun for deer/moose. I was looking to build something interesting for long range moose hunting, and as good as the 300 Win Mag is, its far to common to suffice my need for something different.
Thanks again for the info guys
