Thanks Matt,

Problem solved. Bending the extractor slightly helped, it now cycles heavy snap caps as well as emptys. Do you know if the new safari express uses the cast extractors? If so is it a good idea to upgrade to the spring steel ones?

The magazine follower is topped out against the left rail and is 1/8'' or more below the case when extracting. And just to clarify if you look head on at the bolt face the extractor face looks like an s (much less metal at bottom than an 03 springfield.

Great thanks for the quick reply. I am impressed with the caliber of knowlege and help on this forum.

PS thanks also, Mike

Trying to get the bugs out of a new Winchester Safari Express 375 H&H. It will only extract the LAST case 1/2 way before it falls down out of the extractor 2/3 of the time, even when cycled FAST (rounds in mag hold other cases up OK). The extractor is heavily relieved at the bottom from the factory. Should a new Williams steel extractor remedy this or is there a better part. Would like to fix this myself instead of letting Win. muck about with it.

Thanks in advance.

Please explain this comment, as it might better help in fixing your problem.

Two big factors on that system is the tension that the extractor has on the case. The other is the spring tension on the follower from the mag spring.

First, you might try removing the extractor and bending it slightly with your hand in the section directly behind where the spring collar fits inside the t-slot of the extractor. This will increase the spring tension on the extractor, causing a better grip on the case. Do this only slightly so that you don't put a crease in the extractor tail and put too much pressure on the cartridge case. It may take a couple of times to get it right.

Second, remove the mag spring from the floorplate and stretch it out a little bit. Replace it and try the feeding process again.

If none of what I've mentioned here seems to work, it could be that the part will need to be replaced. Try these methods first before making that decision, as it will save a little money on the pocketbook.

If you have a Model 70 Classic with the old MIM extractor, you need to replace that unit with a true spring-steel extractor from Wisner or Williams. Unless you have an honest spring-steel extractor, many of the virtues of a controlled-feed action will remain lost to you. This is not option, it's a necessity..........

The very newest of all the classic actions have our 416 stainless machined extractors on them, but distributers can have inventory that they later pass on to dealers, who in turn pass on to you, that can be up to 3 years old. I've witnessed this first-hand at a local sporting goods store. We've modified our processes over the years on our bottom metal, some of which would never be detected except by us, but I noticed trigger guards on rifles in the store as new that were made by our company 3 years before, at least.

That relief cut that you're looking at in the form of an "s" is perfectly normal and helps in the cartridge feeding into proper position under the extractor during bolt closure.

A quick look at our website will enlighten you as to the disadvantages of a casted extractor as opposed to one machined from barstock. If after looking at that information and you still have some questions, feel free to call us at our toll-free number listed on the site.

Glad to see the fix worked so far.....Good shooting.

Is there a simple way to identify which type extractor is on a M70 Classic? This one is marked M-R on the inside and can be picked up with a magnet even though it looks like bead blasted stainless. Can't remember if 416 is non-magnetic. Would it be wise to pick up a new extractor and put the old one along with a spare ejector and firing pin in a hole(s) bored behind the recoil pad (properly wrapped)?

Thanks
