lately i have had issues with my 10/22 firing rounds, i always had problems with the cheaper ammo so i started buying high velocity ammo, until recently i wasn't having any problems but now around 1/10 rounds has been not firing, the primers have dings but the cartridge doesn't fire sometimes if i reload it they will fire the second time. I don't know if this is a problem with the gun maybe the firing pin isn't hitting the primer hard enough or if anyone else has had problems with this ammo i was using winchester super X hollow points and remington thunderbolt's. I have also gave the gun a thorough cleaning and i still have the problem. Any advice will help thanks.
