I don't have any experience with an Encore nor elk, but my XP100 in 7-08 is a great deer gun. Three bucks taken so far with none traveling more than a few yards after the shot. 2500+fps with a 140 grain Nosler Partition is easily achieved out of the 15" barrel. Many on here have more experience than I with specialty pistols in 7-08 and I think they will all say it is a great Handgun cartridge.
