Got a new to me Kimber 84 montana .243 and have found the factory ammo it like best, Remington 80 grn cor-loc bullets. Thing is, with that brand ammo I get failure to fire about every 3-4 shots. A google search suggests this is a fairly common firing pin spring problem and a wolf spring would be an excellent replacement. Does this sound about right? I mean, with this ammo I get 3 shots touching at 100 yards, so I hate to give up on the gun. But if I can't trust it to go off every time I pull the trigger, then it is no good to me.

So a new spring and a trip[ to the gun smith sound about right?
