25-06 to 30-06

[tankgunner59]

I don't find much rifle brass at the ranges around here, so I usually don't have much on hand that I don't shoot. So I was wondering if anyone here has ever re-formed 25-06 to 30-06 and if so how it turned out? This isn't a necessity for me but the knowledge may come in handy some time. I've re-formed some 243 into 22-250, not out of need but just to get some experience and I started wondering about re-forming 25-06 to 30-06. it looks like a little of the shoulder would be moved into the neck, so it might not thin the neck brass out too much.

I have done 30-06 to 25-06 many times, and still form 30-06 and 35 Whelen in to 9.3x62mm Mauser and .338-06 my experience has been that necking down works out better and easier than necking up. And to me it is a lot easier to get once fired 30-06 than the other -06 family of cases.

I find sizing up is easier than down. For 25 cal-30 cal a tapered expander would work or possibly 2 steps 30 cal then 33-35 cal and size back down. This allows for a false shoulder to be set to fire form with. The necks should thin and shorten expanding up so thick necks shouldn't be a problem with this, but always check the first few rounds. ( Back a few years a friend sized down 300 308s to 243 and found out the necks had thickened enough they wouldn't chamber, neck turning 300 cases was a chore). By sizing up over size it allows the neck to be formed in the sizing die the false shoulder placed where the bolt just closes under light resistance.

I did it several years ago simply out of boredom and having to much time on my hands while recovering from health problems. I ran the brass deep enough to clear 270 sizer ball before shoving it in a small base 06 die. After trimming I tried a couple of dummies in a Browning BAR. Needed some coaxing to chamber in the BAR but the bolt closed with little or no resistance in either an 03 or 1917 Enfield, can't remember which.

Sorry I can't offer any real advice. Much simpler in my mind to see if anybody on the board would like to trade.

Load the .25 case with a moderate charge of your choice, add appropriate slug, chamber in a .30-06 and fire. Extract, resize and trim. Easy as pie.

When I did it I went up to .270 and then to 30-06. Up was easier. After a few shots I went to 30-06 A.I. I believe I still have a few loaded and ready, as well as some that used to be .270 cases...and a few .280 cases.... and whatever else I could try. I did have a bit of trouble with nickel plated cases trying to go up to the A.I.

[Rcmaveric]

If i neck up, i don't worry about them. Just load em and shoot em. If i neck down, which is what i often end up doing, I turn the case necks. That brass has to flow some where.

[Mr_Sheesh]

It'd be wise to graphite the inside of the cases for expansion, then clean the graphite off before loading. (Or some other lube...) Just go slow & patient, should go well :)

And here I thought I was the only one who did this. 22-250 to .250 Sav, .243 to 7-08, 30-06 to .35 Whelen Imp, the most extreme was 7mm mag to .358 Norma. Wear eye protection and plink them at close range as there will be no accuracy obviously.

I have found .25-06 to be scarce and .270 to be a dirge.

Better to do .270 up to .30-06. The added length of the .270 ensures you will have your ‘06 cases the length you desire from the get go. The .25-06 will likely end up short and you are working the .25 caliber necks much harder than the intermediate .270 necks would be.

I have .270 a plenty and am looking for .25-06. Wanna do some trading?

What he says, post in swapping and selling, I think you'll find your 25-06 brass is worth more than an even trade for 06.

[tankgunner59]

I don't need to re-form 25-06 into 30-06 it was just a search for info. Like re-forming 243 into 22-250, I had to turn the necks and anneal them after re-forming. Just wanted to learn another aspect of the sickness. Same thing here, I've re-formed several 270's into 30-06, I don't need the 30-06. I was just wondering how feasible it might be. Thanks for all of the replies, much info I can use in the future.

[AllanD]

I owned a 25-06 for a couple decades, long enough to completely shoot out not one but TWO barrels and I never considered expanding 25-06 to 30-06.

I have a several hundred 30-06 virgin cases I have yet to Use, but then again I also have a virgin barrel
I'm about to swap onto my R700 30-06....

And slightly more than 1K cases dedicated to my Semi-auto 30-06...

Semi-auto 30-06, is that the venerable M1 Garand? Always wanted one, but can't afford it on disability. So that's one dream I can keep.

tankgunner59,

At least here in TX, .25-06 is fairly uncommon when compared to .30-06 & you can probably trade your .25-06 for clean/deprimed .30-06 cases.

Every year, during the "run up" to deer season I pick up hundreds of .30-06 cases "for the taking" at 2 local ranges at day's end. = Over 500 in <2 days last fall.
(I reform .30-06 into 9.3x62mm cases.)

yours, tex

[Duckiller]

WHY? I like playing in my reloading room but makeing 30/06 brass seems like a real waste of time. I believe it is the most common caliber. If it isn't there is still a LOT of brass out there. If you are going to change one piece of brassm, that is a learning process. If you want brass to shoot then you want to use common brass to form hard to find or rare brass. Good luck.

This is it. Good to anneal first. I use shotgun powder, cornmeal filler and a wax plug for fireforming. Super easy and a sure fit when you're done.

[tankgunner59]

Thanks to everyone for the input. I am not lacking for 30-06 cases, I was just curious if anyone had done this and if so how. I haven't been re-forming very long so I was mainly looking to pick your brains, and I have gotten a lot of usable info. Plenty of help on sizing up for future use.

[Three44s]

My kudos to the OP ..... many thanks and thank you for your service.

After I contacted him he sent me his 25-06 cases he had but would not take any 06 in trade because he is already set nor did he want anything for shipping as he feels he has been blessed here at “Boolits” and wanted to pay it forward!

An outstanding member I must say,

Best regards and Happy Easter!

You might want to just consider buying 50-100 once fired 30-06 brass cases from a number of websites or at gun shows.
The prices can be really a bargain. It will save the need to form and then fire form to your chamber.

Thank you for your service!
WHAT brass are you short on??
Mike

[robert12345]

Prime your 2506 brass,
add 8 to 10 grains Unique.

No need for a bullet.
No need for a wad.

Level the powder !!!...........!

Chamber the primed, charged case into the 3006 chamber.

Pull trigger.
Ka boom !!!

What exits, will b e a fire formed 3006 case.

[EDG]

Not really that involved. Just load with a normal load and fire. Anneal the necks before loading again.
It works the same going the other way. Load shoot then anneal. I still have .30-06 LC 66 match brass formed to .25-06 in 1972.

Hey Mike. Thanks for the appreciation it means a lot to an old DAT. The only brass I am really in need of is 7.62x54R. I save the change my wife has at the end of each week and use it to buy factory ammo like PPU and re-use the brass after firing. Factory is used for plinking and then I reload for accuracy etc.
I am also on the lookout for 7.62x39 when I can find it.

[skeettx]

Thanks,
I have neither of those at the moment, but if I stumble on to some
I will PM you :)
Mike

[tankgunner59]

Thanks Mike, are you looking for anything?

BTW Mike, thanks to you for your service to us and our great nation. Some young people these days don't understand the satisfaction of serving.

[skeettx]

Thank you :)
I have all I need and more.

Going from 25-06 to 30-06, I might be a little concerned about the case mouth being thin. One can always thin the mouth by reaming or neck turning, but making it thicker would be a little more difficult. I also have some .270 that I will be making into 280 Remington before long. Up or down, doesn't seem to make much difference, but to go that much bigger may cause the neck to be thinner than would be ideal. Just my 2 cents worth.

Yeah fast ronnie, thats what I was thinking. I don't need to reform 25-06 to 30-06 as I have plenty of 30-06. I was just curious if anyone had done it and the results. I'm kinda new to reforming and just had some curiosity. Thanks for your two Lincolns.

[calm seas]

I stumbled across a pdf file a while back entitled 'Case Reforming'. Really interesting read. 25-06 to 30-06 is about .051 expansion. I am like Texas by God - I have expanded 7mm to 358 caliber. Why? Cuz I had a boat load of 7MM brass given to me, and no other real use for it. Think I have shot my 7 about 4 times in the last 6 years.

[Mr_Sheesh]

7mm TC/U case forming is similar only more percentage of expansion and case neck thinning doesn't seem to be an issue; Might be more pressure in j-word 30-06 loads but I'd doubt too many here push boolits all that hot? Could well be wrong tho, and PP or PC shooters might do hottish loads.
