I'm pretty much in agreement on the discs - but I had to buy two such rifleslately because they were incredibly priced and therefor I needed them.
skyler4321, did you check out that huntinfo.org link in my first post?
Another rifle you might want to consider (open action and 209 primers might not be as appealing as lesser powered ignition and loose powder is about 1/3 the cost of pellets) are the Whites. Should be legal in most every state that allows inlines at all. Check out Doc's site at
