How many HP's do you run for reliability test?

I would feel woefully inadequate in confidence if I only ran 15x2 rounds through one mag and called it good. A failure at round 31 means a theoretical 3% failure rate. Since you didn't go beyond a larger statistical sampling, one can't say it's 100%.

Guns can cost thousands, and so does training. I paid good money for the gun. I paid good money for the training. I pay good money expending training ammo downrange. 'm going to pay good money for my carry ammo and run enough because my life will depend on it. We all train to overcome failures and stoppages, but we really want to minimize the probability of that occurrence when it's a two-way range or someone with a pointy or smashy object.

For me it's just a couple of magazines and call it good.

My personal comfort level is 150-200 rounds of the JHP I am currently loading for SD. It might be a little more expensive, but I am worth it.

I'm in the same range as "481".

Be Safe!

Actually, I never had a Glock in 40, 45, or 9mm, reject a hollowpoint. Usually back when I was using Hydrashocks exclusivelly, but with all the new ammo with the rubber and plastic tips, theoretically it should be even less of a chance of ftf. Also that magtech is almost as smooth as a FMJ.

This is a statistics question and the larger the sample size the more confident you can be in the reliability of your ammo and firearm as a system. For example, with a sample size of 22 and no failures, you have 90% confidence that the system is 90% reliable. If you increase the sample size to 59 you go up to 95% confidence and 95% reliability. This is an oversimplification since there are many variables. In general more is better up to a point. Once you get to 95/95 you have to increase the sample size significantly to get small improvements. Statistically speaking if you are shooting between 50-100 rounds you should be good to go. Just remember you are testing the entire system, not just the ammo. Make sure you go through all the magazines you will be using, shoot the gun clean and dirty, shoot it strong hand and weak hand, etc.....
