I have even read (somewhere, heaven only knows where) that Marlin has tested spitzers in their tube-magazine rifles and didn't have any kabooms, but the lawyers won't let them okay their use. At least one writer (C. Rodney James, IIRC) has even built a test fixture to try and make rounds go off, and was unable to do so. So I wouldn't worry about blunt nose bullets. It makes me a little nervous, too, when I'm mashing the next round in through the gate, but apparently it takes a pretty good whack in the middle of the primer to set it off. Good thing, eh? :wink:
