View Full Version : Model 16 bolt problem
I have a model 16 that often fails to completely eject a fired case. What do I need to do to fix this problem?
Thanks for any help.

Are you operating the bolt slowly?

What caliber?
There are some fixes, or depending upon what type of shooting you're doing, removing the ejector altogether and picking the brass off the head is one solution I've applied to all my bench shooting rifles. Don't have to worry about losing my carefully prepared brass that way, and it goes right back into the loading tray in the order it came out.
Replacing the ball under the extractor with a 9/64 steel ball may help. A modified extractor kit from SSS will also help. Clipping a turn off the ejector spring might do it too.
In my 223 (with the ejector in place) I found that snapping the bolt back quickly with my finger tips I could catch the case mid flight and place back in the tray. Some still got away from me so I simply removed the ejector. Now I don't have to work so hard.:cool:
IME, the 223 are the worst at failing to eject completely. The reason is that as the case is pulled out of the chamber it snaps hard against the bolt lug abutments, leaving a dent in the case just below the shoulder ( I could count the number of cycles on the brass this way) and that jars it out of the grip of the extractor. So now when the barrel is off the action I blend the corner of that abutment to lessen damage to the brass on rifles I used in the field and want to eject normally.
EDIT to correct size of steel ball in extractor per @Robinhoods suggestion. Good catch RH!

It can also be weak ejector pin spring or dirty ejector pin:)

The cartridge is .250 Savage. I operate the bolt in a slow fashion so I can catch the brass, but it seems that most of the time when I open the bolt, the brass just comes out part way and then lays there so I have to reach in with a pencil and grab the case mouth etc. I have taken out the bolt and cleaned around all parts with a dental pick and Ed's Red, and I still have the problem.
Replacing the ball under the extractor with a 5/64 steel ball may help. A modified extractor kit from SSS will also help. Clipping a turn off the ejector spring might do it too.
How does a guy go about doing this?

Operate the bolt smartly. Use a piece of tarpaulin to catch the brass.

I always use a 9/64ths ball. Should I be using a 5/64ths. :o

Oh my gosh YES....especially in a Creedmoor!:cool:
I still have the problem.
SHUZ: Be sure and let us know what, if anything, you did to resolve the issue. The fix is always a bit more informative than the problem.

I've really done it now, haven't I?
Only now I'm having a total brain fart. Is it 9/64 or 5/16?

If you've never had the bolt apart before, you can search this forum or the interwebs for some instructional videos.
You'll need a 1/16 pin punch to remove the cross pin on the ejector.
The extractor is easier, just slide it off towards the outside of the bolt head. And then order some 9/64 (?!!) steel balls off Amazon. You'll probably get a bag of 100 so you won't have to tear apart your loading room when one launches itself during the process, and that's guaranteed to happen so do your work it inside a plastic bag to catch the flying parts.

Today's math lesson. Converting fractions to decimals.
9/64 = 9 divided by 64 = .140
5/16 = 5 divided by 16 = .312
:p
What is the size of the stock ball used in the extractor?
Looks like I created a lot of confusion on this issue. I'm sorry. For, hopefully the last time, what is the size ball I should get?
thanks,

The stock size is 1/8, or .125” Many have switched to a 9/64, which is .140” for better extraction. Just as Robinhood has already stated. When you see an answer from Robin... it’s pretty much gonna be the CORRECT answer!

I feel as though I am being given waaaayyyyy to much credit. But thanks Dave.
Ok, thanks for the help. I'll get a 9/64" ball. Now I need to find out how to install it. Can someone help? Pleeez!
Thanks,
Shuz

Just a suggestion- Go to ACE hardware or similar, and get a few balls of what came with the bolt and a few a tad larger and see what works best in your bolt. They are no more than sixty cents each and probably less.
Mr. Hood- It is good to see that someone remembers fifth grade mathematics.
