Area 8 this year. When we arrived to the stage next to the Chrono, we were asked for 7 rounds, which were put into a bag with our info.
After we shot the stage, we went to Chrono.. Cleared our gun, put it on the table, the Chrono person checked the gun in the box, weighed it, then shot 3 rounds through the chrono. Then took the avg of the three and determined your PF.
I noticed when they handed me my stuff back, they had pulled the bullet from a round and weighed it.
I was so paranoid about making PF that I nearly freaked when he said "someone modified their gun" when he put it on the scale and it was heavy.. Something I had not even thought about.. But I was within the allowed limits for Production..
