I have two of them, a p1 and a p2. They are tough as nails and are everything that is claimed. One thing that a lot of people don't like about them is that they are velocity and therefoere trajectory specific. Both the rimfire model and the centerfire model have their reticles and rangeing systems set for weight/velocity/trajectory parameters. So you have to find the ammo they like and stock up, especially for the rimfires. For the centerfire model, handloading is best but not really neccessary. Not to steal the thread, I lost a rifle mounted with a Shepherd in the Prophet River (BC). It was washed down about 5 km and came to rest on a gravel bar. It was in the water for three days, if the McMillan stock hadn't floated, probably would still be up there somewhere. Took the stock off and cleaned up the bedding and retorqued the screws, checked out the scope alignment by bore sighting, cleaned the bore and took it to an adjacent airstrip to sight in. Took three shots and it was like nothing had ever happened to the package, other than a few scratches and scrapes. It's been 6 seasons now and it's still fine. The optics are as sharp and clear as any other glass you want to compare it with and the people at Shepherd are just plain nice guys that are great to deal with and will answer all of your questions on how to mount a scope properly and with great patience to make sure that you understand why. I would buy another in a heartbeat and not blink an eye at the price. A great lifetime scope that is easy to use and rugged and can be passed on to your heirs. bearhunter
