I predict that they'll only sell these to people who buy only because it says "S&W" on the barrel. Otherwise, people will buy based on price, and Ruger/Marlin has this beat on price.
At about the 12 minute mark in the above video the reveiwer states that he can not hunt with this rifle in Iowa because it is not a straight wall cartridge. We all know that the 44 Magnum is a straight wall cartridge and is on the Iowa DNR regs as a approved deer cartridge.
