Anybody Make A .35 Long Neck?

[Good Cheer]

Just asking because I'm curious about it.
Anybody using .303 brass run full length into .35 Remington dies to make a .35 Long Neck for cast boolits?
It's one of those maybe some day ideas that never got done. Was thinking that heck, it could be an easy wildcat and somebody is bound to have tried it out by reboring a nasty .303.

I've made 35 WCF brass that way. It ended up being a little short, but functional.

I could be wrong on this ... I think a few rifles have been made in 35 XCB made with a 16 twist

35 XCB long neck of the 06 .. 1/2 way between the 358 win and the 35 whelen so cases can be made with 30-06

35 whelen dies can be shortened to use to load for it

jes reboring does a 35-303 british.

[stubshaft]

The 35/30-30 has a longer neck than the 303 and is a hoot to shoot!

[Tatume]

The neck formed by running a 303 Brit case into a 35 Rem full-length sizing die is actually too long to be contained in the die. It will hit the top and crumple. When I do this I have to cut the Brit case shorter before reforming. Those are long necks, too long for any purpose I can conceive.

I do it to produce cases that I cut to length for a wildcat chamber.

Larry Gibsons .358x57 is such a cartridge. He uses a 35 Whelen reamer and 35 Whelen dies shortened.

Thanks for that input. Making a .338 Federal long neck with 30-06 brass can run into the same thing (depending upon the band of dies).

The 788 Remington 28LN on the other hand used with the original RCBS 7mm 168 grain (was groove diameter for almost the entire boolit length) was made by running 270 cases full length into the RCBS 7-08 sizer and met with no interference.

Just checked a Hornady 35 Remington sizer. Yep, it'll run into interference about an eighth inch or more before getting full length.

[Larry Gibson]

The 35x57 is an excellent cartridge for use in Mauser actions or other actions with tapered side rails. It appears Good Cheer wants to rebore a SMLE or #4 303(?) so the 35x57 wouldn't be a good choice for that. I've formed 303 into a 35 RemR cartridge for use in rebarreled SSs and bolt actions for rimmed and semi-rimmed cartridges. This alleviates the cost of custom dies and a custom reamer as standard 35 Rem dies can be used along with a standard 35 Rem reamer.

The formed 35 RemR cartridge on the left and the standard 35 Rem on the right both have 35-200-FN bullets seated to the crimp groove. The top of the Hornady GC is still in the neck. In a bolt action or other strong action the 35 Rem can be loaded to very good ballistics.

Yep, the Saeco, Lyman, Lee and RCBS 200 grainers are designed to fit the SAAMI standardized .35 Remington chamber dimensions. That case volume coupled with greater barrel contact lengths for the boolits can make a much better cast cartridge. Such is what longer necks are good at.

[Good Cheer]

Found something.
This is the last remaining example of 28LN, formed from 1956 cold war 30-06 brass.
The boolit is the RCBS 28-168 design as it previously existed. The gas check is at the bottom of the case neck.

I have that mould and my short throated 7 x 57 barrel has the gas check way below the case shoulder. I use .270 brass to make 7x57 cases and have wished for a long necked chamber to allow a longer case neck to be used along with a longer throat to get the gas check in the neck where it belongs.

[Good Cheer]

Can you size the interference front part of the boolit to fit into the rifling?

[Outpost75]

Can you size the interference front part of the boolit to fit into the rifling?

Yes, by making a tapered bump die cut with the same throater used to fit the barrel. Or better yet, just cut a mold to produce a tapered nose to fit the throat. Tom Ellis at Accurate Molds does this routinely on my designs. Send him an upset throat slug.

[wmitty]

Thanks for the nose sizing idea; I am gonna try it. Never occurred to me since the boolit isn’t a bore rider.

[Good Cheer]

For 7mm, depending upon what your bore diameter is adjacent to the chamber you might get lucky and be able to use an off the shelf (or off ebay) sizing die. Older barrels especially so as the bore diameter gets pushed back a little. Do you happen to have any sizers for a .270 in the fun box?

[Good Cheer]

I have a actual 0.270" diameter H&I die but that's gonna be smaller than what you need for a 7mm's bore.
0.277" might work for you.

[Good Cheer]

Diameter made to your order (.250" through .600") costs $40 at ssfirearms.
Hmm, that sounds like a lot but not so much as it did a couple of years ago.

You guy’s need to stop, look what you made me do.

303 into 35 rem as far as it would go.

[RU shooter]

My first set of 35 Rem dies were I believe Lyman or pacific and are marked 35rem/35 Win so can do both I guess . So what about the just using the 35 win 30/40 krag necked up

[beltfed]

How about this one:
My 358 Long Neck Beltless Magnum.
built to shoot 282 and 300 grain cast bullets
as well as big jacketed ones.
Started with a McGowan 358 Norma Mag chambered /Savage 110 barrel
Faced off barrel breech end to eliminate the belt.
Ran my 35 Neck and Throat cutter in an appropriate amount
Cases: turn off belt, size in 358 NM FL die, Size again in 350 RM die to push back shoulder

Left to right:
35 cal Clymer Neck and throat reamer
My 358 Win 250 gr PP deer load
3 - 358LNBLM, loaded with 282 lyman and a 250 gr speer
Std 358 Norma Mag
Std 350 Rem Mag
Above is a 300 gr NEI bullet.

I've half-finished a .35 Krag project. On a Krag action. Using a .35 Winchester reamer and dies. Been stalled for a quite a while because JES badly screwed up the rebore of my best spare barrel. Haven't had the gumption to send another barrel to a better vendor.
