Hey Shayn!
Here is a link to a .308 barrel that is currently for sale on this website.
http://www.graybeardoutdoors.com/phpbb2/viewtopic.php?t=40136It is listed in the T/C Encore classifieds forum. You can find lots of great bargains if you just take your time and wait for what you are looking for to come along on Graybeards classifieds.
I just purchased a 7mm-08 barrel for my Encore last week off the classifieds. I got it yesterday. A great barrel. I'm going to use it for deer hunting this year.
Ed has the next best option going I think. A real nice guy and a straight shooter. You'll have no problems dealing with Ed.
Also, E. Arthur Brown and Company run some really good specials from time to time on T/C products and barrels.
I would have to suggest that you go with the .308 as opposed to the .454. I think you will have more options available as far as bullets and components go. Also, tons of surplus ammo for the .308 caliber.
Just about all of the guys on this site are a great bunch to deal with.
Where in Indiana are you located? I'm in west central Indiana.
