It was oddly coincidental how events unfolded the morning of my range test; I brought with me a gun that I was looking to sell, and was finally offered a reasonable price for it ($200) at the range. Funny enough, $200 will buy you 500 rounds of cheap .45 ball. Having just read "Mr. Canebrake's 500" thread a few nights prior, I made up my mind to do a write-up utilizing this function test. Now by round 200 or so, I knew I had a shooter, but with all that ammo on the table it was just so doggone hard to stop!
Cane, I intentionally referenced your method in its most literal fashion because I think it is geared towards the new shooter, and in that respect it is an excellent answer to, "Do I need to break in my new gun?" Seldom is there a single answer to any question, especially pertaining to firearms, but to the new shooter what better advice exists than, "Get out there and send 500 downrange!" The unmentioned side-effect is that, without question, after 500 rounds you will be intimately familiar with the function and performance of your firearm.
So have I or will I put a weapon into service before the 500th round? You better believe it. But for simplicity's sake and in the effort to educate the untrained masses, my vote, Mr. Canebrake, is for you to keep repeating the number 500!
(The more I say it, the more it sounds like the Indy 500. You'd better make it 1000, and call it the Canebrake Grand.)
