IEH, I do not own an Encore, but did have an stw, when they first hit the market...one of the guys over the mt. loved it for elk, he used 175 grain Horn. in his...I used mine for about a year probably, but decided the amt. of powder burned was not worth the speed gained...went to a 7mm Wea. in a 700 action..witht the long mag. box, I can seat a 160 out to the base of the neck on the case...it will kick these along about 3250 fps. With an Encore you could do the same...
