+1 for Greg. A buddy of mine got a scope from him, best price around and great service. I've heard some good things about the Nikon Scopes.
Greg, a 10 year old Mallard? Wow! Take care of the kids, the video can wait.
My buddy has a .44 Mag wheelgun, I'll ask him what scope he's got on it. He just had to buy a Tarus Raging Bull in .480 Ruger. He ran about 40 rounds thru it and put it away, saying that the recoil was too bad. I shot it, and bought it. While I wouldn't want to shoot it all day long, I don't think it's too bad. If I'm using my Muzzleloader and chasing after hogs, that .480 is going along for the ride as well.
For load development work, I have a gun rest that is very similar to the Lead Sled, except that I chain the front end down to the shooting bench. That really saves the shoulder! A buddy really appreciated it when he was playing around with his .375 H&H.
I was kicking around the idea of building up a rifle for deer here in Indiana, but now I'm thinking of building a Striker with a magazine instead. I want something that will reach out 300 yd. or so, and that seems the most cost effective way to do it.
