I'm new to this. What does +P mean?
+P is a SAAMI (Sporing Arms and Ammunition Manufacturers Institute) designation for ammunition that's loaded to slightly higher pressures than standard. SAAMI defines cartridge/chamber dimensions and maximum allow pressures to insure that factory guns and ammunition are safe and compatible.
So you cook, the real question is, do you do windows?

Like said above, +P = + Pressure. ... In many cases the pressures are only slightly more than standard limits and the velocity gain is minimal.
