Jason,
I'll throw my opinion your way. I really like the Bushnell 4200's. An issue that you may consider is weight. The Bushnell is heavy, and this is a big consideration in building a hunter gun. As an action, I would/did go with a 1712 barraled action from Neal Stepp in Texas, and a light weight sythetic stock from Mark Pharr in Texas. Both are on order, and I don't remember the exact estimated weight, but this combo should allow me to mount the Bushnell with room to spare. Thats my best guess at the same problem.
If you're shopping, I think the optics zone and Graf's has 6x24's for about $400 and they also list the scope weights. 1712 action was under $900, I forget the stock price.
I have a 24X Weaver silhoutte scope sitting on the shelf because the optics are not as crisp as the Bushnell. Some people don't mind a little less glass quality, but I have a bum lasik shooting eye, and great glass is essentail to me. My other eye is 20/20, but I need really good glass in my shooting eye or it distracts me. All the (6x24 and 8x32) 4200's I have seen have the 40/60/77/100 markings.
I personally never heard any thing but good comments about 4200's, I did hear poor comments about Sightron quality control. Again, thats not too valid, but thats what I hear. I don't have any extended experience with Sightron, just looked throught a few.
