Knight Ulite or Mountaineer with a bare primer plug and properly head spaced is very easy to clean. Virtually nothing gets into the action. Main thing is to replace the factory bare primer plug with a Lehigh less than $25. Better yet a Bestill Creations plug and have him set it up. You can set it up yourself also for around $80 just for the plug. I strongly suggest a 45cal 1-20 unless you are hunting states that require a 45cal for elk. The 45 fast twist is far more versatile with the addition of a adjustable sizing die.
