I got my custom 375. It was built on a Rem 700 action with a sako extractor.

Problem--Discharge round, work bolt and the empty brass seems to hit the bottom of the scope and comes right back into the mag well. I assume this is a simple adjustment of the extractor and ejector.

Please inform me if this is correct or are there other problems? Any help and information is greatly appreciated. And yes the gun is going back to the smith immediately.

Thanks, PG

Here we go...another Remington battle is about to start on here!

First off...I assume you meant to say that the weapon had a failure to "extract"...not a failure to "eject."

Layne Simpson wrote a great article about this conversion in Handloader Magazine #123...where he relates his own horror stories about the results of replacing the Remington extractor with the "better" Sako or M16 type claw extractor. He speaks of Remington 700's and 40X's with both Sako and M16 type extractors installed that failed to extract cartridges 20% of the time. Before the conversions none of the rifles had ever had a failure to extract.

Oh...the title of his article was: "If it ain't Broke, Don't Fix it."

I would bet that the Sako conversion is not grabbing the cartridge rim properly and/or evenly... and when the ejector bumps the case it is forced up (path of least resistance) instead of off to the side.

The geometric relationship of the extractor to the ejector is very critical...and in this type of conversion the two parts were not designed to work with one another. The "grabbing" area of the Sako extractor is not the same size as that of the Remington...Sorry, but I believe that the Remington extractor grabs a larger portion of the case rim than the Sako does.

Check it out for yourself. The Remington extractor lip that grabs the case is slightly wider than the Ruger 77 Mauser type extractor lip and I'm fairly sure the Ruger is wider than the Sako.

Sako extractors work great...On Sako rifles!

If you want to visually see what is causing your problem pull the bolt to the rear and look at the face of the bolt. Consider the scope to be at 12 o'clock

On an unaltered Remington bolt the ejector is positioned at 4 o'clock and the extractor is grabbing the cartridge rim at 9 o'clock right under the right locking lug. When the ejector bumbs the case it pops it up and to the right.

Your altered bolt places the Sako extractor where it is grabbing the case at 11 o'clock and when the ejector bumps the case it has no other place to go except up and right into the bottom of the scope.

The Sako ejector on a Sako bolt comes through the left locking lug at the 3 o'clock position and when it bumps a case it has the proper relationship to send the empty case up and to the right.

If I were you I would kick whoever talked me into making this conversion in the first place.

Thanks for the input. It is not an extraction problem at all. The brass actually hits the scope adjustment cover. Glen read it correct. Rick, your comments regarding the 11:00 position is spot on. With the scope off, it ejects fine.

Looks like a stronger spring for the ejector and some work on the extractor and maybe medium rings.

Thanks for the comments.

Turning the scope "backwards"(rotate the windage turret to the top) should give enough room for the case to clear- really weird to adjust, but should solve the problem.

You might try Viagra....oh, sorry, misread this post's title
it was EJECTION problem....
sorry, just couldn't resist.............

I stand corrected on my reading of the post.

However, I will stick with my comments concerning installing Sako type extractors on Remington bolts as being a bad idea, in that it purports to solve a problem that doesn't really exist.

Installing this extractor screws up the geometry of the positional (is that a word?) relationship between the extractor and the ejector and short of making and installing some type of deflector, the empties are going to be kicked in the wrong direction to clear a scope.

I can catch and remove empty rounds on a short action before they are kicked by the ejector by slowly retracting the bolt with the back of my thumb and using my first two fingers to grab the case...but you would need some really long fingers to do that on a long action.

All of these problems and Rube Goldberg quick-fixes can be avoided in the first place by just keeping the extractor that was originally designed to work on the rifle. That was my point...and it has nothing to do with any "love" or "loyalty" for Remington rifles or factory parts. I would have the same opinion if people were installing Remington parts on Sako rifles.

The positioning of an extractor and ejector on a rifle is critical to proper functioning and when you change that relationship your are asking for problems like what our friend is experiencing now.
