RE: Which one? Black Diamond or BigHorn?
I have a Bighorn with the 22" barrel and I really like it. It will shoot some really nice groups. I was looking at buying an Omega for the longer barrel, but instead I am going tobuy a 26" barrel from Knightfor my Bighorn. The gun is fairly easy to clean. I really like the gun. Like cayugad said, if you are going to scope it, I would get a scope cover because of the open breech design. Either rifle will perform really well, but I have a soft spot for the Bighorn. BTW I also own a TC Renagade which Ialso love. As you have already said TC makes quality stuff and both companies have excellent customer service departments.
