I own an Encore Pro Hunter in .22-.250 and .300 WinMag. I think it as an awesome piece. TC has made top of the line arms for a long time. I have no problem with their factory trigger. I have had no reason to attempt improvements to it. As far as Re-loading, it is no different than any other caliber or bolt gun. Of course you don't have a Mag box to worry about length but follow the reloading manual for overall length and you won't go wrong. It is easy to change barrels but of course it can't be done on the fly. Mine has the thumb hole stock and it is a pleasure to shoot. You won't regret it. One thing, it can be hard to obtain extra/different barrels sometimes for some calibres. Where are you located, I can show you mine.
One warning, the Encore and the Encore Pro Hunter are different, don't let them confuse.
