500Nitro, as mentioned I was going by more gut feeling than based on my knowledge, which I freely admit I have very little in DR's, but I'm trying.. Mostly my line of thought regarding the price is the maker not caliber or condition of the rifle.. Thats why I'm asking. I'm also looking to be corrected if I'm wrong, but you also bring to thought that perhaps it is priced right due to maker vs. the kings ransom a Brit gun would bring in this highly sought after caliber.. Heaven know's it's got me thinking, and I had my mind made up for a British maker 450/400 someday.. I can only assume the bore condition is as good as the rest of the gun, it was made in 1993
