My 6.5CM shoots the 142g load much better than 120g. I don't have access to a range over 100yds, but I would love to try and reach out a little. I did harvest a buck from 266yds a couple of years ago and it dropped him.So far, so good. With the dry weather and threat of fires here, I've only had it out a few times out to 100 and I'm definitely the limiting factor.
We're getting ready to move here in a bit and there's a range with steel out past a mile a few minutes away, I'm looking forward to properly stretching its legs when we get there.
