I'm looking for a new barrel for my encore and was wondering what cartridge would be best in a 26" barrel? Wanting a hot rod but don't want to be blowing un burnt powder out the end of the barrel. I plan on using for varmints and antelope out to 500 yards. Was thinking of the 6x47 lapua, 243AI, 240 weatherby or the 6x284. Heaviest bullet I was planning on shooting is 95 grain.
