What is this with my brass and what does it mean??

[Nimrod84]

Not to jump start the voting on your re-chambering, but first pick for me is the 9.3x62 with 338-06 as second choice due to availability of components. Nothing wrong with a 30-06 spitting out 200-220 grainers as you know, but the 9.3x62 is in a different league.

I hope your medical testing is fruitful.

When rechambering a .308 to .30-06, the barrel must be set back approximately 3/8" (I think) before the '06 reamer is inserted because of differences in the case body taper or what you have is the result.

Thank you! This seems like what the issue is. Due to how far the ring is up the brass. I will be having it re done before I shoot it anymore. Thanks to all you guys for the excellent info, it is most appreciated!

Thank you! And yes I've had an interest in the old 9.3x62 for a long time. I actually almost picked up a Ruger #1 in that clambering this summer on vacation. I knew my wife would not be happy though haha so I let it pass.

I almost grabbed a 370 Sako chambered rifle (9.3x66) when that round was introduced to the USA. I'm not recommending the 370 Sako as it is pretty much dead in the USA, but I recall it was designed to fit 30-06 actions and bolt faces. The 9.3's from what I can tell, are a really good optimization; at short range they hit like lightning and can be used out to a respectable range.

Looking at SD and BC's, the 9.3mm has a similar relationship to the 375's as the 7mm does to 308.

Good call on keeping the wife happy. I like Ruger #1's, but I appreciate a quick and reliable second shot with the bigger big bores.

That's what I thought too. The oddity is just about where the 308 chamber's shoulder would start...

The ring is caused because the Smith did NOT shorten the threaded end of the barrel and then add additional thread. ( more work). The shoulder of a 308win is wider at that point than the brass on the 30-06. That was done intentionally durring 308 cartridge development so the 308 can't be chambered and shot accidentally in a 30-06 rifle. The taper on the two cartridges is not identical. This is a "little known" FACT.

I have experienced this issue. The brass can be resized and reused. Even reused in a factory chamber. However your gun will always "Mark / Personalize " it's brass. Enjoy the gun . It is safe.

I'm a little late to the party, but this looks to me like just rechambering to .30-06 AI would be the most economical of effective solutions.

Also a consideration for sure.

Quick update on this thread. I shipped the rifle to JES this morning. Hopefully have it back in a few weeks! And he is reboring it to 9.3x62 [emoji16]. So gotta get online and start rounding up all my supplies for reloading it when it comes back. Thanks for all the advice folks!!

I think you'll have a blast with the 9.3x62. It's a whomper.

 

[Cleveland48]

Yep had my sights set on one for a long time! Thinking about the 270 gr speer hotcor. Been reading up a lot on them, seems they are soft for heavy game. Should be fine for whitetail though!

Well I received my 98 Mauser back from JES! It's now a 9.3x62, and did a quick sight in today at 50 yards. Set it with prvi partizan 285 gr SP. got 3 in a 3in circle at 50 yards. Not to bad for the ghost ring aperture, but I think I'll get used to in in time. One big issue was it would not feed when cartridge was on left side of magazine. After spending about six hours today slowly filing away I've got it to feeding. It will not feed if working the bolt very slowly. But if your yanking on it like you hate it she cycles just fine every time. The old plastic butt plate is gonna have to go though! I was expecting recoil to be a little over 30/06 level. With that butt plate though it beat me to death lol. Gonna start rounding up some reloading stuff now!

" I like Ruger #1's, but I appreciate a quick and reliable second shot with the bigger big bores."

You'd be surprised just how fast a Ruger #1 can be reloaded for a second with only a little practice. You can use a belt shell holder, one on the butt stock, a short one on the forearm or ever a couple held between the fingers of the non-trigger hand. Personally I prefer the butt stock method or the belt shell holder in second place but I can reload for a second shot just about as fast as the average one time a year hunter and maybe even a bit quicker, especially on the harder kicking rifles. Learn to work with the recoil to speed things up. Probably takes a lot longer to explain how to do it that actually doing it. I've done a lot of my hunts with a Ruger #1B in .300 Win. mag. and never had a problem getting set up for a second shot should I need one.

After some more work today on the feed rails I have it functioning very good. Just ordered reloading equipment, and gonna try the 286 grain spire points.
