Not seeing any of that resolution in current catalog, so potential buyers should do their homework. https://www.mitutoyo.com/webfoo/wp-content/uploads/US-1005_Mitutoyo_Catalog.pdf

That does look like a quality caliper, but I still think the caliper by design design is unsuited for .0001" resolution and all of those I've seen show a digital readout of 0 or 5 for the 4th decimal. Are you saying yours shows .0001, .0002 etc.? Id hate for a member to buy something that didn't meet his expectations is all. Yours looks a lot like this one.

I've seen digital calipers with 4 decimal place readouts, but they only are good for 5 tenths resolution. If you want to measure head expansion I think you should be looking at a micrometer.

Wouldn't think so, it's actually bleeding off pressure. That is still a pretty warm load, or soft brass based on the ejector swipe. Was it the same make case as the others? Maybe more powder in that one case? I'd back off on the charge weight. Did it pit the bolt face?

Winchester has gone back and forth with nickel plating since the 90's. They had a run of bad ones a few years ago that pinholed.

Winchester primers?

I think the entry taper comes into play as well. You might try flipping that bushing the other direction if possible.

Looks like you are good to go with the .286 bushing. The reason I asked about the O.D. is based on experience with a Redding FL Bushing Die for my .308. That die with thin walled .308 WW brass would size well below the marked bushing diameter. I believe that was due to sizing over .010" in one pass. Redding cautions not to try over .004" in one step if I recall correctly. Good luck with your reloading endeavors!

Caleb, what is the outside neck diameter of a fired case?

Bump for a great 4 season tent. I have been using one for several years.

Factory Five?

Was your Leupold made before 2004 or after? The threads are different.

Thanks, are they marked B/GA T* on the bridge?

Do these have the soft or hard rubber eyecups? Are the objective covers and hinges still intact? Thx Mike

Picture of muzzle?
