The Savage 99 is rumored to come back fairly soon.
Movies have nothing to do with the continued popularity of leverguns. How many new westerns have been out lately? Very few.
Cowboy action shooting has helped with more traditional models being brought back into production such as the Marlin Cowboy rifles. Just look and see how many companies are making Winchester copies. Henry has even expanded their line of leverguns to include 44 mag, 45 Colt, and now the 30-30. I doubt they would have brought these forth without a demand for them Marlin still sells 10's of thousands of new leverguns every year. They have introduced several new calibers including the 450, 308 ME, and soon to be released 338 ME. Don't know much about the 338 yet as it is in field testing now. The 308ME is making the old levergun into something it has never been before. 300 yard deer rifle it is. Lot's of 45-70 have been sold in the last 10 years and they continue to sell good in various models.
Last year was the very first time in history that the 30-06 finally surpassed the 30-30 in ammo sales. This does not take into account all of us folks that reload for the old 30-30. Take a levergun hunting with you and see what hunting is about. It isn't just about shooting at 500 yards. I bet more deer are still killed with old Win 94's and Marlin 336's than any other type of gun.
Some fellers around here make fun of my 30-30 but I have taken more game with it than most of them will ever see. Including lot's of deer, several feral hogs, and even a 420 pound black bear with one shot using factory Rem 170 grain CL ammo. Took a nice bull elk in CO with a Win 94 BB in .375 Win. One shot was enough with it as well.
My heaviest Marlin rifle is my 1895 Cowboy with a 26 inch oct barrel. It weighs a whopping 8 pounds until you load it with 9 of those bone crushing 45-70's in the tube. It will take game out to 300+ yards if the shooter is up to it.
