You should get a few responses on this site. There are a few guys who accurize Encores. I have an Encore with barrels in .264WM, .25-06 and .204. I just got the frame back from www.bellmtcs.com
who did a trigger job on it. It came back with a crisp 2 lb pull. I also have a 1X oversized hinge pin from the same place. I haven't played extensively with it yet, but groups are hovering around the moa mark with the first loads tried.
I also got a beavertail laminated wood forend from www.midwayusa.com
made by Boyd's. (midway is the only place you can get this forend). This forend made the gun ride the bags twice as steady as the skinny factory forend.
These three things can be had for less than $150 total and are a good basic accurizing treatment for the Encore.
You should be able to achieve your goals with your gun. Have fun and welcome to the site! ---Sam
