if I have access to a lathe, a little machinist experience in college 20 years ago how hard is it to ream out my hornet to a khornet? How much are the ream(s)? Where do I get them? Is there really a benefit to doing the conversion? I shoot a handi with open sites...love the rifle but the ammo is Killing me!!$$$ Is there an advantage to the k from a reloading standpoint? --thanks
