A couple of things here. As said previously, the Encore is slightly larger and heavier but with that extra size comes a whole lot of options when it comes to catridges you can choose from. The Contender is regulated to relatively low pressure rounds, think 30-30, 45-70 and most pistol rounds. The Encore can shoot all of those plus any high pressure round up to the head size and pressure level of a 300 Win Mag.
Now are you talking about the Encore Hunter Package or are you thinking about the "new" Pro Hunter model? THe package is just that, complete gun with scope mounted. The Pro Hunter comes with a heavey fluted SS barrel and the hammer can be angle to the side so you can cock it easily if it is scoped. It also has the TC logo on it and the new/better Flex Tech stock. I think the new stock is a huge improvement over the original.
