I'd highly suggest NOT using a higher power. The higher the power you get, the more percieved movement you see in your scope, and the less you are going to trust your hold.......

I'm shooting 6x right now, and thinking of dropping to 4x honestly until I get things sorted and my shooting back in order. I'm supposed to have a 4x coming to me soon, and I will probably use this for most of my indoor season.
