I am consistantly getting about 1 in five fte's. Have used 2 different kinds of Federal (bulk) and Winchester Dynapoints. Have cleaned the bolt face and extractor claws. The bullets are difficult to extract (tight). Any help as this has become a real headache.

I had the same problem in mine, with Lapua ammo. I had someone take a reamer and clean up the chamber, but I have yet to fire it to see if this fixed the problem.

My MkII does that too. Try scrubbing the chamber really well with a brass brush. It should help. My rifle fails to extract a lot more often if I shoot subsonic ammo, probably bacause the bullets are coated with lube/wax and that stuff builds up in the chamber. With copper plated ammo it fails to extract a lot less frequently (but it still happens at times). Anyway I have learned that I can minimize the problem by cleaning the chamber well and often.

There is no cure for it. It's a bad design.

Shooting target grade standard velocity ammo tends to help but it will still happen from time to time.

With 20 years expeirence under my belt as a gunsmith, I have this problem on a regular basis. First thing I ask, is how is what kind of ammo are  you using. Usually it is a mart/bargain box, lead tip. You can get the front of the chamber so gummed up, carbon built up that it is hard as a rock. I have even seen the same thing in a Anschutz BR rifle that liked some of the cheap stuff, that was sorted by weight/rim thickness. I usually soak the chamber/throat area with a good cleaner, shooter choice, take a bronze brush on a short section of cleaning rod, wrap some #0000 steel wool around it and chuck in a hand drill. Then I only insert to the chamber front/throat, run for 15 seconds at a time, then brush and swab with a different brush. Usually clean in 2-3 tries. I had a guy bought a $1500 Anshcutz for $600, tuner and all, because of this, we cleaned it good, chamber and barrel, shot about 40 rounds to condition the barrel. He went back  2 weeks later and won 3 of 5  matches with this gun. Might not be your problem, but seems like what I have run into a lot. The savage action and bolt head are very similar to an Anshcutz, so I think it is a sound design. I have also run into this with Rem. 541's, Ruger 77/22's, Ruger MK 2 pistols. Just my 2cents worth hope this helps.

The problems happens with cheapest Remington bulk, Lapua match and everything imaginable in between.

They also have trouble with hyper velocity ammo like Stingers and Yellow Jackets.

Mine was doing this, and I'm a bit of a gunsmith.

The problem seems to be simple:  Pull the extractor, and you will see one of two things - flash, or unevenness where the part was pulled.

In my case, it was the latter, like this from the factory.

A coarse stone cleaned it right up, and it functions fine now.

As an aside, reading up on this problem, it seems that it's pretty widespread.  Maybe some notes to Savage would be in order to fix their extractor making machine?  Grin
