Since your willing to spend the money... ask yourself this question..."Will I use this rifle for anything other then black powder hunting?" If you do not plan to put different barrels on the Encore then why spend the extra for it. The Omega is a great black powder rifle and would make all those kinds of shots you mentioned. It also has the warranty of Thompson Center should you have any problems or complaints... You might want to go shoulder one somewhere and see how it fits..

I would get a stainless steel Omega with a laminate stock.......

Good luck
