My custom 300 Apex Mauser need's help.Empty or fired brass hits the ejector and just flop's back on to the follower, but flings loaded or bulleted dummy rounds 6 feet across the room.Help appreciated. [Linked Image from i.postimg.cc]

Extractor tension. You likely don’t have enough

How does one correctly increase tension?

Bent the tail gently(twice). No change.It will throw a bulleted round time after time 4 feet. An empty case at best will make it half way out then bounce back in and lay on the follower. [Linked Image from i.postimg.cc]

Show a pic of the boltface & ejector. Too little or too much claw contact with affect ejection. How much extractor deflection is there when you slip a cartridge rim under the extractor claw?

Pull the bolt back like you mean it , or replace the extractor with one that has not been beveled to snap over the rim

There were also 2 styles of ejectors, one has a round pivot hole, and one has an elongated hole...you might try swapping. They are pretty cheap on ebay.


Well this is a fine pickle we're in, should'a listened to Joe McCarthy and George Orwell I guess.

Look's a little blunt on the underside.Baffled why it ejects loaded rounds and not empty's. [Linked Image from i.postimg.cc] [Linked Image from i.postimg.cc] [Linked Image from i.postimg.cc] [Linked Image from i.postimg.cc]

Loaded rounds have more momentum due to the extra weight so they continue to swing out. Empty cases don't so the sit. This is often a sign that you have too much extractor tension. Check how much defelction you have when you insert a case under the extractor claw.

Here's one other thing to check (something I've found in similar situations). Remove the scope - then try again... I've had several instances of EMPTY cases hitting the RH scope adjustment knob at just the right angle which dislodges it and drops it back onto the follower... Maybe this is not the case here, but it's one way to eliminate a possibility..

Brownells used to. You have to fit the extractor though. When I had this problem with converted mausers I built it was those 2 knubs were not tight enough to hold the case head against the extractor and them. Then the shell would fall out of the bolt. No amount of tuning the extractor would help.

It's not the two nubs, it's the extractor claw. If the claw isn't correctly fitted, the feeding, extraction, and or ejection can be adverversely affected. That's why I said measure the extractor deflection. Replacing the extractor may or may not fix the issue and may ultimately need to be fitted to properly work. My guess is that there is too much tension. This is likely why loaded rounds will be thrown free while empties struggle to come off the extractor. But what do I know?

How does it feed? Often, in an effort to overcome improper mag box geometry, the extractor claw can be shortened too much so as to allow the rim to slip underneath. This too can cause the case to not be thrown free. Measuring your extractor deflection will tell you whether your extractor has too little or too much tension so you know what countermeasures to employ.

The claw is not holding the shell.The claw is worn and most likely too short because no matter how much tension on the tail I can't get it to grip the shell.How much shorter would the claw have to be with a new extractor for the magnum boltface approx.?

What you're describing makes me think that what you have right now is a 'standard' extractor - and not the magnum version...

The exact opposite would be true if he had a standard extractor, the claw would be too long. The claw on a magnum extractor is shorter due to the rim being larger than on a standard. .532" vs .470".
