someone inform me of what the differences of standard ammo/+P/+P+ is?

>>33130085
higher pressure, more bang

+p is higher pressure than standard. Depending on cartridge there may be a standard for +p as well. +p+ is above the +p standard when it exists.

>>33130085
Just higher pressures from the powder loadout. You'll gain some added performance at the cost of more muzzle flip and generally more flash

how do they "pressurize" the ammo?

>>33130120
So more pressure could mean over penetration possibly?

>>33130085
+P+ is not standardized by SAMI, +P is.
>>33130148
Ammount of poweder essentially P=NRT/v if you want a formula.

Not necessarily, but the +p I remember seeing test on ShootingTheBull didn't expand properly, so something did act as FMJ and over penetrate. The velocities aren't much higher in a pistol either. I'd just use standard 147 grain hollow points in a pistol, use +p in a rifle

Just do your research on +P+. Not because of snappiness but because the added velocity can actually result in a decrease of penetration thanks to the drag from the added expansion. They also have a tendency to shed pedals because of that as well.

>>33130160
It usually means less penetration because the bullet is traveling fast enough for proper expansion. In cases where expansion is the same either way, then more velocity would help the expanded bullet travel.

I just use standard 115gr gold dots myself, out of a 3.25in barrel.
