Angry 8400 extraction problems

Saved up and finally got my ultimate Montana elk set up, Kimber 8400 in 338 Win mag. However when firing Federal 225 factory ammo extraction of the spent case is difficult to nearly impossible. Bolt lift is normal and brass shows no pressure signs. I tested my reloads which have less of a problem but still extraction is far more difficult that it should be for low to mid power loads. I checked several forums on line and this appears to have been an issue in the past. Has anyone run into this issue and what is the solution?

Speyman, welcome to the site from Tennessee.

Rick may have some insight for you when he comes along.

speyman, you don't say if the extractor lip is slipping off the cartridge rim, or if the cases are difficult to extract without tearing off the rim.

The Kimber 8400 uses the time-proven Mauser rotating claw extractor. This requires that the tempered steel extractor has a slight 'bend' in it to give the proper amount of tension. Too much bend, and it's much too aggressive, too little, and it'll slip off the rim.

If you're handy in the shop, remove the extractor, note the amount of deflection, then put a slight amount of pressure on it to increase the bend slightly. Chances are this is all that's required, but if you're not comfy with doing this, then a call to the Mothership will be required, or a quick trip to your local smith, as it's really not a big deal to remedy.

Oh, and welcome to the KimberTalk forum too, good to have you aboard, even if your first post had a "mad" face.
