Hey PNW, first of all thank you for your service to our country. On your question about the Bighorn, IMO great great gun, you wont be disappointed. I have 2 of them and out of both the plain 310 grain Knight sabot with 100grs 777 give me great groups. I have the original sights on one and on the other i have a Williams peep sight.BTW check on line auctions for them, my second one I picked up brand new,in the box for 145 bucks. My only bitch about them is the short stock, but Im looking for the thumbhole version, abit longer an seems to fit me better. Hope this helps. Stay safe.
Sage
