Wow! Great rifle, great calibre, and great price.
The 7mm-08 is essentially a .308 with slightly better ballistic coeffients, although I would guess the difference is negligible, since the 7mm and the .308 are already the top two bullets in terms of ballistic coefficients already, in the bullet weights that they take, around 100 to 150 grains.
It is a good thing that you reload, and you will want to stock up on brass, which is the hardest part to get. The bullets, primers, and powder are easy to get.
I always used magnum primers with my 7mm-08 and that worked extremely well.
I was getting 1/4 MOA accuracy/consistency.
Unless the bore is worn out on this Savage, it should perform well. If the lands and grooves looks sharp when you inspect it with a light, then the bore is probably fine.
The reason I finally got rid of my own 7mm-08 was simply because I wanted one rifle for elk, mule deer, blacktail/whitetail, and pigs. And the 7mm-08 will not do all those things. I needed a .300 to do all those things.
That may be why your seller is getting rid of it. Or else he fell in love with something new. Shooters are remarkably fickle, as am I.
