Would casing extraction jam be an issue of not enough lube after 200+ rounds? I have sprayed the slide whenever i get the jam and it corrects the problem so i can get back to shooting again while at the range. Could it be that im using dirty ammo like remmington umc from walmart? The federal ammo works flawlessly but has had some extraction issue when i didnt clean my gun with the hops brand. Please let me know of some input before i might have to send it back to Ruger.
