Hello, Last year I acquired an old Remington Model 721 in 270 and am uncertain of round count. (Rifle appears in very good condition.) To my disappointment I have had several misfires with this rifle. I eject the round and notice there is still a healthy dent in the primer so I am miffed about my problem. The Winchester primers I use have never given me any grief in the past so am leaning towards a gun problem. Could it just be my firing pin or a problem with one of the springs? Any help would be greatly appreciated. I really like the rifle and want to use it for hunting but right now just don't have any confidence in it. Thanks in advance.
Wanted: Help with misfire problem!

things to check:
protrusion of firing pin - is it damaged?
Main spring - could be broken. weak, or gummed up with crud / rust
Headspace - extreme excess headspace can cause poor contact with primers
Your handloads - shoot some factory loads for reference, could be seating of primers, oil comtamination of primers, over-sizing, dirt in flashhole, etc.
I've had all these things go wrong at one time or other.
good luck!

I have a 300 H&H in a Remington model 721. When I first got it, it was doing the same thing. Dented primer misfires with factory ammo. I took it to the local gunshop, talked with them. I ended up buying some CLP Break Free, and a bolt disassembly tool. I took the bolt apart and soaked everything overnight. Put it all together and it has worked awesome ever since.
There was a lot of hard grease that came out. It seemed very dirty inside.
Give that a try.
Let me know.

Start with the simple stuff mentioned above: i.e. clean the bolt and firing pin mechanism.
Had a similar problem.. once.. in cold weather, when I neglected to clean all the oil from the bolt of my rifle. Outside was wiped clean but the interior?

Art,
You can take the bolt apart with your boot lace, clean the hell out of it and try again. Striker springs are a dime a dozen, so changing a decades old spring isn't a financial hardship. The decreased locktime can be a real eye-opener. Beyond that, what Longwalker said.
