Ian McCollum of Forgotten Weapons has a fine review of David Royal’s A Collector’s Guide to the Savage 99 Rifle. I know some people think that Winchester or even Marlin lever actions are the be all and end all of lever guns but my heart belongs to the Savage of which I have two. Both of mine are in .300 Savage.
Royal’s book was published in 2016 and is available on Amazon in the $40-43 range. There are 52 reviews of the book there and 92% of them are 5 star! I plan to get a copy and suggest other Savage 99 lovers may want to as well.
