.250 Savage necked up to 6.5mm

Have any of you guys played with the .250 Savage necked up to 6.5mm? I am looking for a new project, and this one looks like fun. I know that a lot of other rounds duplicate its likely performance, but since when did practicality figure into our decisions?

I've thought about building one for many years. Came close with the 6.5 Arasaka, 6.5 x 54 and my sporterized 6.5 Carcano. Just finished putting the barrel on and firing the .250-3000.

My intent was to deep throat it like the 6.5 X 55 which I also enjoy. If your intent isn't to use bullets over 120gr. you may as well stay with the .250. The smaller 6.5s I've used were good deer killers with the 140gr. plus bullets. Good choice and good luck if you go through with it. Looking forward to reading your results.

I know that there is no practical reason not to go to the .250 Savage, but since when did practical have anything to do with it.

Many years ago there was an article in Gun Digest on "mildcat" rounds, which included a .270 on a .250 Savage case. If I recall correctly, it pushed a 130 grain bullet at about 2700 fps, barrel length unremembered. I believe it was intended for Savage Model 99s with throat or bore problems. Seemed like a reasonable round for deer sized game.

I suspect a 6.5 on the .250 Savage case would generate about the same or slightly better ballistics with a 120 grain bullet.

Depending on rifling twist, I believe this would closely resemble the 6.5X50mm Arisaka, which is a little smaller around, and slightly longer. I beieve case capacities would be almost identical, for identical ballistics.

The 6.5X50 Arisaka is an excellent small cartridge!

I had a 22.250 case get mixed into some 243 brass that I was necking up to 260...

Anyway, I loaded it up with a 107 grain Sierra Match.. I caught it before I fired it in the rifle as I single load it at the range..

I disassembled it when I got home....

However, I had to admit, it was a neat looking little case with that 107 grainer on it...and I believe in the old adage "if it looks right"...

If I did up a wildcat just to have a project to play with.. a 6.5 x 250 would be real close to the top of the list.. that and a 6.5 WSSM..

I found a 6MM X 250 FL sizer at a gun show cheap and bought it to use as a form die for another cartridge. It does make a neat looking round. Once fired 250 Savage rounds are expanded enough in the case neck to seat a 6.5 bullet with almost no sizing. I prefer the tapered cases to the straight bodied rounds.

Seems you would be better off with a 260 and loading it down. Maybe the 6.5x47 Lapua.

I saw something on another forum that the 6.5 x 47 Lapua is just that, a 6.5/250 Savage...

And, isn't the .250 necked to .243 called the "6mm International", or something like that?

Of some interest,Maybe: In a search to build another wildcat I necked down some .308 cases to 6.5, driving the shoulder back to what the .255-3000 has. I trimed hardly anything off the length as I think leng necks are desireable.

Of course the idea was to more adequately handle the longer bullets when mated to a rifle with a deep throat as in the 6.5 X 55 yeilding a perfectly useable deer rifle with low recoil. Desided not to spend the money but have dummy rounds that I look at now and than. Dreaming is nice.

The 6mm International is indeed the .250 Savage necked to 6mm.

My idea is to shorten a Mauser 98 to Kutz length and build from there, hence the .250 parent case. If the Lapua round really is the .250 necked to 6.5 mm, that would be interesting. I also considered trying to modify the bolt to work with the 6.5 Grendl.

I have thought for a while that the 6.5/.250 would be about the perfect practical deer/varmint round in the quest for such a concept. With a 8" twist and handloading it would do 95% of anything for which most of us use a rifle. Sort of a modern 6.5x54MS.

Of course the bean counters will poo poo it. But custom dies, reamers, and barrels are good for the economy! Plateau Hunter

of course loading a 260 to 6.5 x 54 specs or to 250 Savage specs, with the same bullet weights... you will get the same performance...at least in mine I do!

I built one of the 250 [6.5] for a guy in Hawaii about 25 years ago for his daughter. I did the chamber with a piloted 250/3000 reamer and then opened up the neck to 6.5. The dies came from CH4D and it shot REALLY good. It was on an old Swede Mauser and it handled the pressures fine. I have no idea what velocities it got but it sure killed a lot of Molokai deer and goats!! Throw in a few Halawa Valley oinks too.

That should make a nice round. In my wildcatting, I've always preferred the eficient cartridges like this rather than the ones that just keep stuffing more powder in and trying for every last ounce of velocity. whether they need it or not

) The 250 is a great little cartridge that has been used as a basis for a lot of fun calibers over the years.

I like a reason or an excuse for my projects. Only one I can see for this would be a Savage 99 with a shotout .250-3000 barrel

I set the barrel back on a 6.5 jap and chambered it to 6.5/250 and got .... a 6.5 jap! Oh well, not everything is a winner.

Out of interest, What velocities do you anticipate with 130AB or 140NP in 6.5/250sav??

I would be surprised if you could not get 2500 fps. with the 140 gr. bullets.

Have not looked in awhile, but I have an older book about Silhouette shooting, and I believe rifle and pistol-xp100's were chambered for those shooters by gunsmiths in a HOST of calibers on the 300 savage case....
i.e. 7mm IHMSA, etc. I remember 6 and 6.5mm. This may be the same round. I think they were done to slightly less recoil vs 308 case, while keeping minimum taper and sharp shoulder....high pressure rounds.

I saw a fellah with this set-up at a range here in virginia. It was a sporterized arisaka. He did not seem to really know what in the hell he was doing reloading (his uncle made the reloads)but the gun really shot and looked nice in a non-military stock. I was impressed. He was shooting 140 grainers and doing quite well.

Improved, this is the 6.5 Creedmoor.

Buy a Ruger in 6.5 Creedmoor,it's ready to go and it has outstanding accurcy.Save time at the reloading bench and award yourself with more shooting time. Yea..I'm happy with mine!

Not quite! The 6.5 R-Bar has a longer neck than the .260 and a greater shoulder angle. It is built on a standard length Mod. 98 action and has a deep throat to accommodate longer heavier bullets that are not pushed into the Powder Room. The performance with the longer bullets exceeds that of the .260 with its short neck, short magazine and minimum throat.
