I have both a Traditions and a CVA inline ML. They are both .50 cal. I use Musket caps as well because they are so much hotter. I was told by a game warden that the so called sealed breach ML like the Knights, Thompson, etc are not legal for use during ML seasons. The nipple must be open and exposed to the elements. That said, if you use a ML during modern firearm seasons, you can have a scope, sealed breach and jacketed bullets. This is because you are modern firearm hunting. But that is only if you have modern tags. My Traditions has a "fire dome" breach plug set up. I have never had a hang fire since switching to that plug. I shoot pyrodex pellets and power belt bullets. I use 295 grain power belts for deer and 348 for elk. I use two 50/50 pyrodex pellets, which is 100 grains, behind both loads. I have found that my groups get bigger with 150 grains. If you go shopping around you will see many cheap ML around the 120 price range. Both of my guns cost less than 150 bucks, and both shot well past 150 yards. Groups are around three inches at 100 yards on both guns. I have killed deer at 110 and 150 yards. A buddy used my CVA on a deer at 150 also. I have only killed one elk at 40 yards. I have the fiber optic sights for low light also. FisherDan had a bunch of info he shared with me when I first got into ML around 4 years back. You may want to check the archives for that. Another good place to stop by is the ML shop on River Road near the Clarks Creek bridge. They were very helpful and there prices are not bad. Wal-Mart has a complete ML package right now. I think the gun runs around 180. Just remember that the nipple must be exposed, the bullet for deer must be solid lead with no jacket, sabots are legal is the are at least .40 cal and lead with no copper jacket, .50 cal for any other big game. No scopes or glass tube sights. When I got into the ML stuff, I was told by several people you can't go wrong with a inline, pyrodex pellets, and power belts. Simple to use and simple to load.
