Extractors: Sako vs Mini 16 ?

Changeling

What are the pros and cons of these two systems. Action will be a Rem 700 short action , cases will be Dasher up to 308 size Lapua brass.
 
If you know Pat Byrne (BR Hall of Fame) ask him. His Sako extractor went down the raceway and went through the metal trim on his doorway behind him. His face was peppered with powder and the gases from the chamber. His girlfriend is left handed and shoots a lot. It would have been through her eye and into her brain. He replaced all his bolts that had aftermarket extractors.
Think about it!
 
I had a pt&g bolt with a Sako extractor & cone breach let go a couple of years ago. It almost took my eyes out. Good thing I had glasses on. It looked like a Mauser It was blown out so much. You could see the firing pin & spring thru the side of the bolt. It let go where the extractor cut is. I called Dave Kiff. He told me to pound sand. I'll stick with the three rings of steel.
 
The mini 16 and full M16 extractors were introduced to bolt rifles because the Sako extractor is very weak and almost always blows apart in an overpressure situation. The Mini 16 is much stronger and more reliable, but if you are going to use a case with a 308 size rim, the Full size M16 extractor is the best choice as it is by far the strongest and most reliable.
 
I recently had this discussion with a buddy who is building a mk13 for me. He has a lot of time behind the early mk13s and we are going with the standard Remington extractor. Not to Crane spec, but it seems the sako extractors (etc) are a solution to a problem that didn't exist.

To add to that, they had to cut their scope bases due to ejection issues with the Sako units. That probably isn't a big deal for our range queens but for a guy using it as a work rifle shi!t like that is unacceptable.

I hadn't heard the accounts of Sakos blowing off but that cements my choice to NOT duplicate that aspect of the build.

Chris, I agree with you. A few factory extractors have failed, but I've never had one fail in over 50yrs of shooting.

And replacements are $11 :) Maybe because they rarely break?

I like the "Ninja Factor" of the Sako and M16 extractors but in the end I'll need a reason to change from factory.
 
The only advantage to a Sako or M16 extractor is that if you manage to break it, it can easily be replaced. Once you blow the recess area of the face of a 700 bolt (which I have done) you are up the creek without a paddle and must have a different type of extractor machined into the bolt face leaving you without a rifle until the bolt is modified. With Sako and M16 extractors, you can keep extras in your shooting bag. But unless an extreme overpressure situation happens to you, there's really no reason to change the factory extractor.
 
So does that mean that all the custom actions that use the m16 style extractors are unsafe?

just wondering,

Joe

No. The M16 style extractors are very strong and extremely reliable. Thats why custom actions often utilize them now.
The 'SAKO' style extractor is weak and unreliable under excessive pressure, and in some cases as described above, unsafe. There's nothing wrong with either of the M16 extractors in my opinion.
 
Ive seen actions with the extractor cut under the lug so the bolt face ring of steel is still intact. Cant remember which one that is but i was impressed
 
PT&G will no longer cut their custom bolts for Sako extractors. They are honoring all orders that are in the pipeline but all new orders will not include a Sako extractor.

Dusty if you remember please send me a PM.
 
WOW! I had no idea that the Sako extractor was an accident waiting to happen.

Once when I was receiving replies to a posting (while back) I was even told I would have to change to a Sako extractor if I built a dasher. I think I had better PM the guy and let him know what you guys have said.

Now I'll have to find out if the Mini 16 extractor will work with the Dasher case in the Remington action without any problems and if there is really a problem with using the Rem factory extractor.

Thanks guys for your replies :o
 
Dasher is a standard .473" bolt face so the mini 16 or the Full size M16 will work fine. They cost a little more to have installed, but well worth it over a Sako IMO.

He could leave the factory extractor in tact, but the M16s are much more reliable at getting cases out of the chamber
 
Thanks LS, I want everything to work correctly and as well as possible. This rifle will be for my son so I want everything to be great.
However I still have to find out if I will lose the ring of steel if installing the mini 16 extractor.
