I don't have Encores but I do have three Contender G2's along with a dozen or so barrels. All are carbine barrels in a pretty even mix of factory and MGM. All of the MGM are extremely accurate and I've never had trouble with any of their barrels. Most all of the factory barrels have also been accurate except for one 23" 204 Ruger barrel that wasn't very good. It got outshot significantly by a CZ527 204, so I sold off the TC barrel. Do have one other custom barrel from SSK in 221 Fireball and so far I have not been impressed with it. Haven't had it long but from the couple outings so far it isn't doing so hot. Anyway, my 2 cents would be that you can't go wrong with MGM and I'd get one of those, but if for some reason you have to get factory you will most likely be good with that too.
