I'm no ammo expert. I can only offer what I see in catalogs. One particular standard caliber ammo choice of interest was about 1000fps as described. Then there was a +P selection listed as 1100 fps. So to me, +P adds 10%. Not sure what +P+ might be. Just as a guess- maybe another 10% above that? Making for 1210fps? Naturally resulting in higher pressures, velocity, and energy however those numbers are calculated.
