What caliber to have a 22-250 bored out to?

[pull the trigger]

I am considering having a single shot bored out, most likely JES, what caliber say you? It's a rusted Wickliffe, and I don't need another 22-250 Wickliffe. I've been all over from 358 to 44mag, thinking 18" long also.

250 ai.

6mm x 22/250 -

[Bent Ramrod]

.250 Savage, with 10" rifling twist.

[Texas by God]

JES rebores to .338” minimum I believe.
.358 or .35 Whelen, .35x57mm, .375-06 is where I’d lean if the original barrel is thick enough at the muzzle.
Wickliffe- drooled over those before…

The 250 is an interesting idea, I like the 375 whelen idea, but don't know about dies.....same the 375 raptor, 376 steyr...

[rockrat]

358 or 356 Win, 375 JDJ if Jess has the reamer. 45 Raptor

[Good Cheer]

If for cast I'd look at .338 Federal with an extended neck length for more lube grooves.
.338 and .358 have the same goofy problem, short necks designed for jacketed bullets.

Do I need to keep the same base size, or can JES cut the extractor also?

[Good Cheer]

He made a .223 into a .41 Mag.

[Rapier]

The 22-250 has a standard rim diameter of .473 same as the 308 based cartridges and 30-06 based cartridges. Without an extractor/ejector change you are home with a standard bolt face cartridge.

Before you posted this, I thought about the 41mag, the base is already too big tho. Looks like a straight wall case has to be at least a 444.
I'm sort of leaning towards a 257 Roberts right now, I load it for my dad already ,but would need to find more brass, which is kind of a daunting task, I was very lucky to have some folks on here help me last time, I'm afraid the well may be dry.

[stubshaft]

257 Roberts is a great deer cartridge! Although I'm partial to the 7X57 myself!

6mm x 22/250 -

:)

I built a 6mm x 22-250 nearly 30 years ago. VZ24 Mauser.
I twisted it 1:12. 85 gr and under.
Shot my best 5 shot group with it: 0.062" @ 100 yds. 70 TNT.
My notes show it shoots 85 Speer 4 shot groups of 3/8" at 100 w/ H414.
It solved my "problem" of wanting something different when I had a case of WW 22-250 brass around (2665 pieces, if I recall correctly).

It is Very close to the 6mm International (again, as I remember).

It's basically a 243 eh?

[TurnipEaterDown]

It's basically a 243 eh?

Well, kind of close. Particularly if you do the Improved, which I did.
Improved is something like 1/10th inch shorter at shoulder.

The unimproved is smaller - there is round about an 8% gain from improving a 22-250 if I remember right, so the 6 International is probably something like 11% smaller in volume than a 243.

For me I would probably go with 358 Win. That’s one caliber I have not owned and seems everyone that does own one loves the caliber. Being you can make the brass from 308 gives it an inexpensive source of brass and 35 cal. is great pistol bullets too big enough for anything.
Seems like a real versatile caliber.

358 or 35 whelen were my first thoughts, but now I'm leaning towards the 250, brass availability with the 22-250 is better than the Roberts I think. Too many options!!

[PositiveCaster]

The 22-250 has a standard rim diameter of .473 same as the 308 based cartridges and 30-06 based cartridges….

This is slightly misleading. Although the rim is the same size, the case diameter ahead of the groove is smaller than the .308 etc. Why does this matter? It provides a bit of room for a properly-sized reamer to cut the diameter you actually want instead of what the legacy reamer provided.

For my factory-chambered .250 and .22-250 rifles I use reformed .308 brass for a tighter fit of the case in the chamber, more like using a minimum chamber. A minor point, but still…

Very interesting, thanks

A 35 caliber wild cat based on a .250 Savage length .473” case would be neat and what Remington should have done with the .35 Remington at the turn of the century.
It would have to have been based on the 7mm, 7.65mm, or 7.9mm Mauser cartridges (pre- .30-03).

According to his modest website, JES doesn't bore in the 250 savage. Any other recommendations? Thanks

[marlinman93]

You really need to call JES before going any further, and ask him if he even does a .25 caliber rebore? Not sure he's doing anything that small, so best to see what he does before going any further.

[pull the trigger]

Just got off the phone with JES, he will turn a 25-20 into a 32-20, but other than that, 338 is his smallest caliber. If I still want the 250-3000, he recommended I go to a fellow in Oregon. Also, he charges $25 to cut and crown a barrel.

[murf205]

Will this be a range toy or hunting round? If you hunt where the ranges are not super long, I have to cast my vote for a 358 Win. Brass is a no brainer, dies will not break the bank, it is not temper mental with regards to powder selection, and you can fire form with pistol boolits. Get it done by JES with a 1-12" twist and you are good to go with jacketed. Wildcats are more expensive to create.

[pull the trigger]

The Oregon guy is a fair bit more money than JES. I'm leaning towards the 358 now. Any suggestions on shortest barrel length?

[MarkP]

I like the 20" BBL's on my 350 Rem Mags. I had JES rebore a Rem M Seven Predator in 223 to 350 Legand with my reamer for 0.359" cast. It has a 22" fluted Light Varmint bbl. 1:16 twist. My 350 Rem Mags shoot cast very well all have 1:16" bbl's. They shoot 273 gr cast well out to 220 yds. Furthest at my home range with safe backstop. I can shoot the RCBS 200 gr at jacketed velocities with decent accuracy. Also I have one 350 RM sighted in to shoot LEE 158 gr FN bevel base at 1,350 - 1,400 fps. Approximating 357 mag rifle. As many know the 35 is a very versatile and relatively easy to get shot shoot well. 358 Win with a 1:16" would be the "Cats Meow"

[Good Cheer]

If it's going to be a hunting toy instead of a target rifle I'd go with the largest bore size of cartridge that the piece will accommodate.

[Jedman]

The barrel length on a single shot like your Wickliffe is really your choice for looks and what you want to do with it. A short barrel like 18” usually looks kinda stumpy but if you were using it as a blind gun a short barrel might make sense. If you do go with the 358 I wouldn’t want less than 22” but whatever length it is now is probably the way to go unless you don’t like it.

It's 24" now, I was thinking 20", just didn't know how the 358 responded to short barrels.
I was considering going 444 but the brass availability isn't as nice as 308, I really don't know, there's soooo many options and choices.

[farmbif]

35 whelen might be worth looking into. extractor will work without modification, its in jess's wheelhouse, 30-06 brass is easy to find, plus it shoots cast bullets real well with the very common and much duplicated RCBS 35-200

[pull the trigger]

It's on my short list.
