I will bet that barrels dont last as long today as they did years ago.This must be due to the cost of machining a very hard steel.

Why would you say that?

Shootaway - PERHAPS barrels might not last as long in average hands these days, but IF so, might that be because of combos of the following?

1. Today's average rifleman who is wearing out barrels is likely shooting a lot more than in the past, is shooting higher velocity cartridges (using more powder), is hand loading to higher pressures, which increases throat and barrel erosion, is hand loading slower burning powders (which increase burn time at the same or higher temps, and burn time X burn-temp = more erosion still)? And perhaps the less knowledgeable modern shooters are shooting their more easily obtained rounds too quickly, which could overheat the barrels and increase their destruction rate,/decrease their life?
