I was shooting off some factory ammo today, planning on reloading the empties.

I shot several Hornady rounds, then went to a Nosler round with Winchester brass. The round would not allow the bolt to close.

I compared the two side by side, the ejector groove on the Winchester is steeper. The rim thickness is the same, the rim diameter is within .002 of each other. Case length the same, OAL the same within .02.

The only thing I can think of is the angle is too steep to allow the ejector in.

Any ideas?

Extractor.

Take the bolt out and see if they will fit under the extractor and down in the bolt face.

Seems unlikely that is the problem with Nosler ammo in a Model 70, but you never know I guess.

Yep, it will fit under the extractor. It just won't allow the bolt to close.

I'm curious if the angle of the groove may be locking the bolt down tight and not allowing it to fully close. There is virtually no wear on the extractor.

I just compared a Federal round. It will allow the bolt to close. The angle is steeper than the Hornady but not as steep as the Winchester.

I may just chalk it up to the extractor.

But now for a reloading question. If the case sizes, length, diameter, etc are more or less standard. Then why isn't the angle in the extractor groove? Or is it pretty much not an issue for the most part?

I have seen extractor groove problems with some foreign made ammo & shell holders, etc..
But for the most part, it is not an issue with American ammo in American guns.

If I were you, I would call Nosler and let them know about their premium grade high dollar ammo not fitting a Model 70 Winchester though.

They might send you something nice for pointing it out to them! :D

rcmodel,

I doubt they would bother the time to respond.

I already sent them a nice email pointing out that the way they packaged thier premium grade high dollar ammo, tends to cause the points to deform.

That's part of why I was using intending to use it as target ammo for the brass in the first place.

I won't get suckered into ever buying it again. :neener:

See if the rounds will feed and chamber from the rifles magazine. On some older controled feed guns this is the only way a round will chamber. You have 3 types, push feed, controled feed, push/control.

Regardless of the rumors about rifles with Mauser-type claw extractors, cartridges can be loaded directly into the chamber of some models, but true Mauser type actions will be damaged by frequently loading in this manner (if it can be done at all) as the extractor has an angular cut on it which makes it able to snap over the rim of the cartridge.[ http://en.wikipedia.org/wiki/Winchester_Model_70

243winxb,

I seem to be convinced in my mind it's the steep ejector groove angle of this particular brass that's the issue.

It's the only variable.

Just a matter of checking brass from now on, before buying any bulk I can't use.

I don't see any plus in working on the ejector.
