Last week I posted a question about shooting rifled slugs through a smooth bore and their accuracy. I had stated that eventually I was going to purchase a 20ga. H&R Ultra Slug Hunter. Apparantly, the compulsive side of me has decided that "eventually," isa lot sooner than later.

So I'm gearing up to buy the gun, and I'm thinking about putting a Nikon Slughunter on it (with the BDC reticles). Anyone have this scope? What are general opinions on it?

With regard to the Nikon Omega, I understand the concept: Use their "receipe" of 150gr. pyrodex (or equiv) and a 250gr bullet and your bullet drop will be x at 150yds, x+1 at 200yds, and so on. What I don't understand about the slughunter is how can they (being Nikon) put together a scope that will work with all shotguns? 12ga. vs 20ga? Lightfields vs Barnes Expanders vs any other slug on the market?
How can Nikon make 1 scope to fit all applications in this instance? Or, is it crap? Do I have to sight in at 50, and then figure out what distances the remaining reticles actually apply to? Not trying to over-complicate things, it's just kinda working out that way. Any insight is appreciated.
