Im looking at some marlin .22 magnums...a couple are tube fed and a couple have detachable box mags. The tube fed ones look like nicer guns but ive never owned or fired a tube fed gun and dont know what to expect. What are some of the pros and cons? I like the fact that they hold alot of rounds, and no sore thumbs from loading a detachable mag. But is the spring tube itself difficult to re-insert when the mag is fully loaded? Does it get annoying having to unscrew the tube and empty the mag when they call an "all clear" at the range, as opposed to just popping out a box mag? Or is it not a big deal for you guys? Thanks for the info!
