Rifle bores wear out much faster than pistol bores, and rifles that are shot a LOT in a short amount of time wear out their bores even faster than normal.
The test in the link is useful for determining the difference between the types of ammunition tested, but when applying the test results to handguns, one must understand that the specific round counts from the test shouldn't be thought of as paralleling the bore life of a similar test involving pistols.
It's true that steel jackets will probably wear out the bore faster (just as in the rifle test), but just to pick some numbers out of the air, it might wear the bore out after 20K rounds instead of 50K or more.
So, let's say you save 2$ a box on this ammunition vs. what you would normally buy.
Let's say it wears out your bore after 20,000 rounds (400 boxes). By that point, you've saved $800 on ammo costs. So at that point you spring for a $200 barrel and keep shooting--you're still $600 ahead.
Even if the bore wears out after only 200 boxes, you're still $200 ahead after replacing the barrel.
The luckygunner article states the same general idea applies to rifle barrels even though they tend to be more expensive and also tend to wear out faster.
