I own two 99's chambered in .300 Savage. One is a 1943 model that came with the tang mounted flip up sight (missing!!). Been trying to lay my hands on a replacement rear sight for eons, and have missed two of them by minutes! The other rifle is a later model (mid 1950's I think), and have not had it out of the safe in years.
A year ago I ran across a factory built "presentation grade" one in .300. It was as new, and appeared to be unfired. The metal was all deeply engraved, and the wood was a beautifully finished oiled walnut. They had a $2500 price tag on it!! The dealer told me as I was walking out the door to bring him a $2,000 check, and it was mine. I mulled around for a couple weeks thinking about it, and a collector came in and bought it for the $2500 price tag!! Still crying about that one. 99's are a serious collectors item, and they pretty much have a cult following. You also might put Hi-Walls and Lo-Walls into that cult category as well. I know where a 99 chambered in .308 is, that's part of an estate. They guy that owned the rifle was a friend of mine, and I doubt he shot two hundred rounds thru it. He used it one week a year to shoot a moose in Canada. The stock has a two inch long scratch, but otherwise is mint. Easy to fix as it's not deep. I wish Savage would do another run of them chambered in .250 Savage, 7-08 & .260, and .300 and .308.

P.S. that .308 in the 99 will shoot further than you think. At least 350 yards, and maybe 425 yards
