I have a Thompson Balck Diamond .50 cal, stainless with synthetic stock inline with fiber optic sights. I got it at Wal Mart for $300. I would recomend this gun to anyone. Also, I would never shoot powder again after shooting the Pyrodex pellets. This gun can handle different ignitions, but I use the musket caps, which may be required in Wa. Using a sabot bullet, you can get pretty good shot groups at 100yds. I would recommend this rifle, if you buy a cheaper one and then buy fiber optic sights, you may spend @ $200. Good luck-----
