Frequently Asked Questions

What does 'hot ammo' mean in firearms terminology?

'Hot ammo' refers to ammunition loaded with a higher propellant charge, resulting in increased muzzle velocity and pressure. It does not refer to the physical temperature of the cartridge itself, but rather its ballistic performance and power.

How does 9mm +P defensive ammo differ from standard 9mm range ammo?

9mm +P defensive ammunition is considered 'hotter' because it is loaded to higher pressure and velocity limits than standard 9mm rounds. This typically enhances its terminal ballistics for self-defense applications.

Is it safe to use any 45-70 Government ammunition in older rifles like the Trapdoor Springfield?

No, it is not always safe. Specialized, lower-velocity 45-70 Government rounds are designed for vintage firearms like the Trapdoor Springfield to prevent damage or injury, as modern high-pressure loads can be dangerous in these older actions.

Does 'hot ammo' mean the bullets are physically hot to the touch?

No, 'hot ammo' is a colloquial term referring to the ballistic performance of the cartridge, specifically its higher velocity and pressure. It has nothing to do with the physical temperature of the ammunition.
