Gun metal tensile strength
What type of steel is the barrel on the Remington 870 Express Super Magnum made of & what is the tensile strength ?
Do different manufacturers use different thicknesses / types of metal on their barrels in order for them to be able shoot a 3-1/2" shells ?
Since we like to accessorize / personalize our shot guns how important is to take into consideration weight & length of barrels / mag extensions / etc? When it comes to handling characteristics ?
With lots of practice with your weapon of choice does it really matter ?
