I have been wanting one of these ever since reading about them in old books and hunting stories. Other than ammo availability and odd bullet dia., is there reasons to not buy one? What would you consider a reasonable price for one in good condition that has been altered ( D&T , sling swivels installed etc..) ? How much effort and expense in having one re-barreled? Can the .22 HP be loaded down to .22 WRM power levels? Pics of your 1899 and info would be appreciated.
