The new shells are the Hornady Leverevolution the ones made with a pointed shell. The .450 comes in a 325 grain shell. If you sight it in 3" high at 100 yards it is only 2.2 inches low at 200 yards. They have a soft tip so you can shoot them in a lever action. You can can see them at the hornady web site. They have got great reviews.

As far as the magnaport it is loud. Mine is one of them that is ported and you definitely need to shoot it with ear muffs.
