Murby Scope Update!!
 

Looks like it was the scope after all.

Hornady called me and said the ammo I sent in was grouping 1.5 inches at 100 yards.

So, I replaced the scope and I am seeing clovers now!

I bought the Nikon Slug Hunter scope from Scheels.com. When I told them I thought it was defective, they sent me a prepaid UPS return tag to send it back. (I didn't even have to pay for shipping). They then asked if I wanted money back, credit, or what.. I said to replace it and they had my new scope to me within 2 days after they got the return.
+1 for Scheels.com as their customer service was excellent beyond expectations.
