Do you weigh your carry ammo?

There have been some threads here, on guns, and Glocktalk about hollow points, 9mm, and that incident with the NYPD when 4 Speer Gold Dots did not expand. Out of all these threads throughout I picked something up, weighing your carry ammo. Last night I weighed 150 rounds of 147gr HST standard pressure (P9HST2); they all came out to 13 or 14 grams depending on what my postal scale felt rounding to, only had 2 rounds come in at 12 grams.Do you guys do this? If so, what do you carry and what do they weigh? via /r/CCW http://ift.tt/1YM32EW
