The speaker clarifies that while +P has standards, +P+ does not, highlighting the potential dangers of over-pressurized ammunition. The discussion touches on the expertise of handloaders in understanding specific pressure data.

Quick Summary

There are official standards for +P ammunition, ensuring safe operating pressures. However, +P+ ammunition lacks a maximum standard, posing risks of firearm damage or failure if used in incompatible guns. Handloaders often have the most detailed pressure data.

Frequently Asked Questions

Is there an official standard for +P ammunition?

Yes, there are established standards for +P ammunition. These standards ensure that the ammunition operates within safe pressure limits for firearms designed to handle it. Exceeding these limits can be dangerous.

What is +P+ ammunition and does it have standards?

+P+ ammunition is a designation for rounds loaded to even higher pressures than +P. Crucially, there is no maximum standard for +P+ ammunition, making it potentially hazardous if used without careful consideration of firearm capabilities.

What are the risks of using over-pressurized ammunition?

Using over-pressurized ammunition, particularly +P+ rounds in firearms not rated for them, can lead to catastrophic failure. This can manifest as 'blowing up your gun' or creating dangerous conditions due to excessive internal pressures.

Who has the best knowledge about ammunition pressure limits?

While general standards exist, individuals who handload ammunition often possess the most detailed and specific knowledge regarding pressure data for various loads. They are a valuable resource for understanding precise ammunition limits.
