It took me sometime time to find all the o-rings for the Vulcan 3 .22 cal now i have life time o-ring supplies and it cost me around $30 oringsandmore.com
I have both 500 and 700 in .22 caliber I love the 500 very compact and easy to handle i got Donnyfl sumo on it shooting 30gr slug laser accurate and very quite very happy with the rifle
I have 5 tins of H&N hp II 30gr in .217 1 tin open but not missing any slug I would like to trade with H&N .218 message me if you have .218 25gr and up and would like to trade
