Sagebrush wrote:+P ammo is only in the 38 special and the 9mm.
+p stands for plus pressure in the 38 from 17,000 psi to 20,000 psi or 18,500 cup........the 9mm is 35,000 psi
and a +P around 38,500 psi.
Any weapon from 1945 in good condition can shoot +P ammo and most have +p stamped on the weapon.
45 acp does not have +p ammo...............
Sagebrush wrote:Velocity vs Penetration.........
True they all play a part, also the amount of copper and its hardness or makeup that goes into the bullet
plays a big part on how it will open up as well as how soft/hard the lead or all copper bullet is, covered by the jacket.
Pure lead, cast lead, Silver tips, Gold Dots, HST designs all open up at different rates per the fps that they are fired at.
Most are great SD bullets if shot at the correct velocities for the bullet to work.....this is the secret !!
One reason the snub nose gets a bad rap for its short barrel and low fps it produces but newer powders and bullets are
making it better.............
and yes, you can drive a bullet TOO FAST , preventing it to penetrate due to an extra large frontal area or even having it separate from its core. Most companies give data on how their ammo should be used or ask that you call or get in touch with them to learn what is correct.
