That, and you were operating with cannon barrels, made of good stuff.
There are few modern day guns that actually use cannon barrel type steel for their barrels.
Even using the proper materials, in today's day and age, I really doubt they use enough of the good steel to make this possible.
Load good ammo.
Stop if there's a problem.
Use common sense.
Chances are, you'll never need a range rod, but if you do, get the RIGHT one, and use it correctly.
