Using steel ammunition (as opposed to brass) "may" wear your gun out "slightly" faster. But by the time that happens, you'll have saved yourself enough money for a new gun just from using the cheaper steel ammunition. Your gun is made to be used. It's made to shoot.

To wrap things up, here’s what you need to remember:

• Brass is generally cleaner to run than steel because it expands better and creates a better seal, resulting in less fouling of the chamber and receiver.
• Steel is more robust than brass and may extract better in some guns (AKs, FALs, other short cycle guns firing intermediate cartridges) because it’s less likely to get ripped up by an aggressive extractor/more violent extraction cycle.
• Brass can be reloaded, steel can’t unless you want to turn your gun into a grenade.
• Steel cases may be more likely to get stuck in the chamber, particularly in lightly-extracting guns like the AR-15.
• Steel cases are usually coated for better performance, and the differences between coatings are relatively minor.
• Steel-cased ammo is not necessarily less reliable or accurate than brass.
• Only you can decide what’s best for your gun and your particular circumstances.
• Test all ammo used in a defensive firearm extensively, and test range ammo as well if you can.

这个要看用什么枪。就算弹壳容易抽不出来，在靶场练习不是大问题。这里的意思是枪的extractor不太给力会导致卡壳，如果是练习的话，正好练习排除故障啊。真正影响的是比赛或者家防的场景。

一般来说这种卡壳都是很容易处理的，最多耽误你1到3分钟。
