1000 words,with .650 BC 250 Skinners. Hint.





This throat kisses same at 3.515". 225 Speer Form Loads,are halfa fhuqking foot shorter. Hint.



Just saying.............

You still around? Only 57,000 posts! You must have Barnacles on your butt! Do you have legs?

If you load shorter you have less pressure, if you load longer you have more pressure. As you get close to the lands by loading longer pressure increases. The increase in pressure from loading longer near the lands outweighs the decrease in pressure by having more case volume by loading further out.

Have you used the Speer 225gr for anything other than forming? Just curious.

Good info from older post,checkout the big bear taken with a .308!

Great old thread. Just got my 338-06 back from JES. Going to start necking up some brass soon.

Finally got to shoot some of my new loads in my new rifle.
I can't get the first couple rounds to eject after firing with the magazine loaded with 5 rounds.
The bolt pulls them back easy they just lay in front of the bolt instead of flying out like they should.No matter how hard I pull the bolt back.
The last 3 will eject just fine,what does this mean? Maybe a worn ejector or the pressure of the lower 3 rounds is enough to keep the ejector from working properly?
I feel like i'am sorta fire forming this brass now anyway, has anyone had a issue like this before with resizing once fired 30-06 brass to 338-06 in a old pre-64 Winchester 70?
Got to thinking after posting this and came back to edit.
I can put 5 loaded rounds and run them thru and everyone ejects like a champ😁
What is going on different when they are fired & spent?Shrinkage & weight?

Check out the ejector, may be sticking a bit. Also, pull the bolt and see if a cartridge will slide into the extractor and sit firmly on the bolt face. If it won't sit on the bolt face, pull the extractor and give it a little bend to tighten it up.

Sounds like a weird problem with it being so intermittent though.

I wonder if the the bolt face has been cleaned/ polished to much & is smidge loose makes it seem the extractor is short?
If that is the case what would be the fix I will have to buy a new extractor to test?


Another good read I found on the 338-06 here.

Could be but I'd bet if you tightened up the tension of the extractor I think you'd have it.

Need to check that thread out.

Thanks for the help beretzs will try it.
Found this today.

Hey fellas, I just listed some new, unfired, Weatherby 338-06 brass over on the classifieds, if anyone needs it.

My 338-06 is on a pre-64 M-70.
Prefers 210-225 gr with Nosler 210 PART getting the nod.
Accurate. Early 3-X Leupold works well.

Other than new cases, anneal case necks.

I ran new WW brass fwiw.

Would a 8x57 Mauser have enough meat in it to be made into a 338-06?

I'd think at worse you might need to lop a thread off, but maybe compare a chamber drawing to see for sure.

I'm not tracking - why would you need to set back a thread to turn an 8x57 into a 338-06? Or is "at worst" the operative phrase? Even then, there is so much steel to work with in the difference between an 8x5 and a 338-06 chamber that I can't imagine having to set back a thread in the course of a rebore.

Maybe I'm missing something.

Yes, exactly. Worst case scenario. You're right though, plenty of meat on the bone for a single swipe in about any case.
