How do I win a special event!!

CandieDisilvio306

My question is every weekend CC2 has the "special events" that you can win if you get "X" amount of points and I have been trying FOREVER to win one of these!! Is there any suggestions you might be able to give me to achieve this goal? The gun that I'm using is the NATO VSK-99 with the ACOG scope. I know that I have to get head shots so I've tried using the redux pills for the entire mission but I time runs out before I can achieve the points that are required. Any other ideas? I REALLY want to win at least one of them. If you read this question to this point that's 15 seconds you will never get back but thanks for taking to time to help :-)
