Chernobyl was safe,
Chernobyl WAS safe, the complex ran safely for many years.
Until, the COMMUNIST in charge (who was an electrical engineer, NOT a Nuclear engineer) decided they needed to run certain "tests". Tests that the Nuclear engineers said were risky, and that the experienced operators said were DANGEROUS!!!!
In America, and nearly all the rest of the world, workers could have refused to perform the dangerous tests. They could have walked off the job, if that was what it took.
In the Soviet Union, this was NOT an option. Simply put, the greatest nuclear disaster to date happened because of Communism, the Soviet System, and placing an under qualified but politically acceptable person in charge, who's orders could not be disobeyed.
How many rounds before a pistol is "reliable"???
Opinions clearly vary.
One mag load. Assuming the mag is proven reliable. A pistol will either work with specific ammo/load or it won't.
I would accept this for testing a particular load in a pistol of already proven reliability. I would not accept this as good enough in a new, unproven gun.
A few years ago, a friend bought a Kahr compact .45ACP (I forget the specific model). The manual recommended firing 200 rounds before judging the reliability of the gun. He could not do that amount of firing, because he was recovering from surgery on his hands, so I got to do the honors. 200rnds of ball, 50 JHP. Total malfunctions, 4. NONE within the first 50 rounds. 3 between rnds 50 and 150, one more before round 200. ALL were failure to fully lock shut. No failures during the 50 rnd JHP shoot.
Another thing learned during the break in was that the sharp plastic checkering on the backstrap of the pistol was a very effective flesh (& cheese) grater. A strip of electrical tape solved that particular issue, BEFORE blood actually started to flow...
Another thing to remember is that new guns are NOT shipped lubricated and ready for use. The oils and greases they are shipped with are PRESERVATIVES, not lubricants. They MAY lubricate the gun well enough for it to work, for a time , but that is not the reason they are there. Clean and properly lubricate a new gun, before use, otherwise you are not getting a true impression of the mechanism's proper function.
another point is doing the break in shooting with cheap ammo. Understandable, and economic, BUT, possibly giving you failures that are the result of cheap ammo, and not the gun itself.
Starting with the gun in a normal carry/ready condition, meaning clean, cold, and properly lubed, a couple hundred bobble free rounds would give me confidence that and much smaller number of rounds I might need to use in any conceivable defense situation would be trouble free.
