25-06' what to do ........

As with everything I seem to get into there's more to it than meets the eye .
History .
The rifle was purchased in 1970 by my Dad . He bought 2 on his FFL the other for what was probably his best friend . Bing passed away from cancer in in October of 78' . In his last days he asked Dad "isn't it hunting season ?", "yeah it is." " What are doing here ? Our days are over . Take that boy hunting ! " . I don't know what became of Uncle Bingos white line , ebony tipped , grade A walnut , double border 1/16th diamond checkering , 24" bull barrel , 700 BDL , with a 4-12×50 before that was a thing everyone had to have . I do have Dad's . It probably doesn't have 1,000 rounds down range he quit shooting it much after Bing passed away , maybe 10 rounds to foul up up the barrel , check zero and kill a deer .
He always said it would shoot 117s but 120s opened up to almost 3/4" for 3 but the 117s even on a bad day would cover 5 with a nickle every time .

So moving along , I have several 25 cal moulds and the rifle will go see my guy with all the cool tools soon .
I'm wondering about a slick side fat 6mm for a paper patch or maybe a heavy 6mm maybe a sort of pointed , spitzer like 110 ?

I have mastered the skills and alloys in smaller cases maybe I could get 27-2800 out of the 260-120 NOE with a little 2500+ .

Of course I might not be ready to shoot Dad's rifle yet . So ......... bring it along , share some ideas let's talk about getting a top shelf 5 under a dime capable sub caliber rifle going for target work and maybe a whitetail or a hog or 6 . If nothing else there's always the fall back to the Partition 117 gr .

I'll follow this. I have my uncles old tang safety Ruger77 in .257 Roberts. I have not tried cast in it yet. I really haven't done any load development at all with this rifle. I did buy 50 pieces of new Nosler brass and a box of 100gr Speer Hot Cores. 4350 is where I'll probably start.

I have a 95 . The start load for the Roberts was the ticket right out of the gate with IMR 4350 and it was plenty of throttle too .
I shot a hog , 96# sow I think , head on , head down , about 55yd base of the skull . I had blood shot clear to the elbows and 4 ribs . In hindsight I probably should have poked her in the eye .

Oops that was a 100 gr Game King .......

You can try slick cores for patching but it never worked for me at all.

I'd t think real hard about powder coating gg bullets, 3k fps is no problem in either 5.56 or 6mm. With easy 1.5 moa or better accuracy.

all of my 25's except the 25-20's see copper wrapped lead.
odd one 0-6 and one Bob love the Hornady 120gr hollow point. [and my other one loved it too]
the others won't shoot them even loaded backwards.
one gets the speer 100gr boat tail controlled expansion as it's 'shoot everything from rock chucks through deer' bullet, and the other Bob gets 86gr remingtons at a sedate 2400 fps when I carry it in the truck.
the 250 Ackley doesn't really seem to care what I give it.

Don't have anything chambered for 25-06. Only study I've done on 25-06 has been for a Model '95 chambered in 30-06. As the original 30-06 cartridge produced little more pressure than the 25-06. The early model '95s chambered for 30-06 have a nasty habit of stretching the action or hammering back the bolt face with standard 30-06 pressures.

or more likely 8-9.
I really wanted to get into some higher vel mid bore cast rifles a couple years back but the amount of molds available, the wide range of throat shapes in my rifles, and the lack of custom cutters made it pretty hard for me to get all wound up about getting started.
the gas check availability thing wasn't really making me all warm and fuzzy either.

neither of my Ruger 25's had the same throat shape, and they wouldn't even come close to sharing ammo with the Mauser.
it's bad enough segregating brass for 3 rifles [and making brass for one of them from 270 cases] throwing 3 molds into the mix just to shoot some holes in some paper was more than I wanted to deal with.

I had three 30-06's for a while . I can appreciate the chamber and bullet situation .
I already have a 257 I could really just wear out if I were inclined to shoot a 25 cal a bunch . In this rifle it's not too much about searching the fringe there's a bucket of Sierra 2nd 87gr HPs if I want to poof a rock chuck with a 3500 fps bullet . I was actually thinking maybe running it back down to a warm 250 Savage . Much like I did with the 264 WM it's a hot modern action 6.5×55 . Just cause you have a Calloway kit in the Vett doesn't mean you have to run it with 60 inHg all the time 30-35 inhg is plenty to to get a ticket or shut down a rental stang' .

It wasn't that long ago? Marlin was making those "sleeper" X7 in 25-06.Thats the one for me which will go down as a miss,shoulda coulda. Load hv cast..... that thing would be a hammer on varmints. Even have a nice old early-mid 60's? Lyman mould.

This would probably be the rig which gets me off the fence on making GC's. We have sheets of copper laying around.Make the dies to handle thicker material and swage some 1/4 jackets..... then launch them at 3200,with linotype,haha.

I can't help on any cast .25-06 loads but I do have a big cased .25. Couple of years ago, I purchased a single shot rifle in .25 Ackley Krag Improved. This is the full length .30-40 Krag case of Spanish American war fame necked down to .25, in fire-forming, case taper is blown out nearly straight with a 40 deg. shoulder. The rifle is on an original Sharps Borchardt hammerless action (left fac. 1880), with 26" med. heavy brl. of unknown make, 1-10 twist. rifle smithed by Charley Durham of Denver, and stocked by Jerry fisher in the mid 1960's. The bore looked new, so I did a fire-one clean break in. I soon found this rifle shot better with lighter loads. For break-in I used .257 Roberts start load with 100gr. Speer Spitzer using H4895. I went down to near .250 Savage start loads with even smaller groups. I tried 87gr. Speer TNT and was getting 3/4-1/2" groups at 100yds. A 1960's era Leupold 7.5 with fine crosshair came with rifle. By this time, weather became too cold for shooting so I spent winter cleaning all copper from bore & casting various .25 bullets. This Spring, I tried a NOE 100gr. f.p. g.c. and with 18gr. H4227 I am getting 3/4" groups..but fliers. I was sizing to .258 & found throat was scraping lead all around front band..scraped portion miked .2580....the bullets cast of diluted Steriotype metal..about like Lyman No.2 were springing back to .2585" I sent bullet samples to Corbin for nose-first sizer to bring them to .2580 & .2575" dia. This is where I am today, haven't had time to try new loads. I have several .25 moulds I picked up over the years, both Lyman and earlier Ideals, as well as the 100gr. f.n. & 120gr. fn. RCBS. And a couple of custom plain-base ones as well...this rifle will keep me busy experimenting for a long long time. And that's what I love about shooting cast..there are so many things to try..alloy, lube, gas-checks, wads...and on and on, I never get bored..unlike merely reaching into a box of factory jacketed and pulling a handle.

Got 25's back on the brain.....

Might start looking for the X7 mentioned above.Not welded to that idea though.... might be a Roberts,might be the 250 Savage.

Not concerned with GC availability,will make them.

What light for calibre moulds should I be looking for?... away from home but,I " think" the Lyman we have is an 87 grain? If so,how's that in say a 12 twist 250 Savage running wide open?

Kind of thinking short action but wouldn't kick a cheap X7 to the curb.

NOE has several moulds . I think if a rifle will shoot 117s well the 260-120 will get the job done .
Moulds only seem to be available in bulk for 80-90 gr bullets .

Home...

RB,it's an old Ideal #257464. Lyman third ed. says it's 90g.

In a 25-06, they list 33g of IMR4198 is good for 2770fps @35,900 as a max load.

I may end up with the '06 cause,even though I would/could prefer the 250Savage or 257 Roberts..... the boys probably be better served with a straight 26-06. But there is a #257420 Lyman 68g...

Looking through my handy inventory .....
Herters 25-80 a very pointy single probably for a 250 Savage
Lyman 257312 a 50% meplat 100 gr FP , I don't think above 1900 fps it can be made slpash proof for game .
NOE 247-120 in both a PB and GC . I think this is the best bet for the for the 25-06' .
I started chasing these moulds when I came into a soft SR Mauser in 257 Roberts.
When I find Dad's books and his mark ups , I'll probably start whith his pet loads for it . 5?.? WWII surplus H4831 seems familiar under the Nosler and Serria flat base 117s . I have 8# of W857 I got for the 264 WM , it loaded very close to H1000 so it might be just the ticket for my heavy bullet/slow powder bit that works so well in others .

maybe with a little kicker, the 25 cal neck is pretty small to try and shove a plug of powder down.

Personally I've been drawn to IMR 4350 .......but there's 2-3# of the 4831 and I recall that ........ Stories about scoop it full to the base of the neck weigh and match ......

Ten years ago tomorrow my wife gave me a Tikka T3 25-06. I love this " virtual magnum" cartridge and rifle. With it's favorite loads it shoots sub moa to 1/4 mile if I do my part. I played with cast in it but I have other guns better suited for that. I use 75 gr Sierra hp for general use and switch to Nosler 100gr Ballistic Tip or Sierra 100gr GameKing for deer. My gun does not care for 120gr bullets of any brand I've tried. No matter- the 100 grs circa 3200 fps kill deer right quick.
