Frequently Asked Questions

Does shooting steel-cased ammo before brass-cased ammo cause extraction failures in handguns?

No, this common internet myth has been debunked through live-fire testing. Firing steel-cased ammunition followed immediately by brass-cased ammunition in a handgun, like the CZ P-07 tested, does not cause extraction failures or stuck cases.

Why might some people believe steel-cased ammo causes extraction issues?

The myth likely stems from potential issues in certain rifles, possibly due to higher pressures or specific chamber designs like non-chrome-lined AR-15s. However, this does not typically translate to handguns, which have different operating dynamics and chamber pressures.

What was the test procedure to debunk the steel vs brass ammo myth?

The test involved firing 100 rounds of Wolf Polyformance steel-cased 9mm ammunition through a CZ P-07, immediately followed by several magazines of LAX brass-cased 9mm ammunition without any cleaning or maintenance in between.

What handgun was used in the steel vs brass ammo myth test?

The handgun used for the test was a CZ P-07. The test aimed to see if switching from steel-cased ammunition to brass-cased ammunition would cause any extraction malfunctions or stuck cases in the firearm.
