RE: Why did you buy "that" caliber?
I have a 7mm RemMag. I bought it because it was a browning which I always wanted and it was priced cheap. Someone in the shop dropped the gun and took a couple gouges out of the stock so the store priced it about two hundred less. I walked out of the shop with a Browning A-Bolt 7mm RemMag with a 26 inch barrel for just over 500$. It was a good choice because last time at the range I shot four groups of three and three of those groups were around .75 MOA.
