Yeah snarky fits ! -= please yrself - you wanna be that feller ? go for it - not my fingers - there is some perceived risk for no practical gain is the main point - no practical gain using a round nose boolit in a tube mag as compared to a flatpoint so why bother? I agree the powder mistakes way more likely to cause grief.
almost 70 and still got all me fingers and toes and never bent a set of wheels (heading for two million miles and I was not the old dude holding up traffic either!!!) - dont think I have a mindset problem - nor a fear problem.
ps google it - the henry story checks out as does some of your contention regarding 30/30 etc -------round nose boolit + federal pistol primer + dumba$$ in a hurry loads ten and drops the follower under full spring tension = kaboom!!!
