Straightwall 35 caliber?

[DeanWinchester]

Of all the old straight walled cartridges, was there ever a 35 caliber?
Is there a straight walled 35 caliber longer than the 357 maximum?

[texassako]

.35-40 Maynard(2.06"), .360 Nitro Express 2.25" show in the Donnellys' book. There are some long 9.3mm cartridges as well. 9.3x82r looks ridiculously long.

[frnkeore]

If you want LONG and fairly straight, try the 9.3x74R cartridge. It's not to uncommon for brass, I think RCBS carries it.

Not a factory round, but one which I have had great success with, is the .35-30 Marquart, which is simply a .30-30 necked up to .35 with no other change. John Taylor relined for me an old 1894 Winchester which had a trashed bore, and I had Veral Smith at LBT make me a 260-grain plainbased mold. It gives ballistics very much like the .38-55 with cast. My rifle has a 16 inch twist.

Outpost, that's more like what I was thinking about.

How in hades do you get load data for such an animal? It would certainly be an easy build.
I was thinking more of a single shot type rifle. Maybe an old Remington Rolling block? That lever gun of yours is sweet though. Bet that'll meat on the table any day.

Load data is no problem. Case capacity with 200 gr. bullet seated to 2.5" OAL is same as .35 Remington, so use that for a guide. www.hollowpointmold.com modified a Saeco #351 for me, shortening the nose, enlarging the meplat to .25" and hollow pointing, while widening the base band and cutting a new, wider front band to fit the rifle throat, as shown below. Expanded bullet was cast 1:25 tin/lead and fired with the 8.4 grain Bulleye load into water jugs at 50 yards.

Ten-shot strings. NO FILLER!
7.2 grs. of Bullseye 1050 f.p.s. - Sd 37, necks smoky. DO NOT REDUCE
7.8 grs. of Bullseye 1250 f.p.s. - Sd 19, clean shooting hot weather load
8.4 grs. of Bullseye 1313 f.p.s. - Sd 11, Max. useable without any leading
9.0 grs. of Bullseye 1371 f.p.s. - Sd 17, Some leading. DO NOT EXCEED.

With the 260-grain LBT bullet as a heavy hunting load I use a nominal "caseful" of either RL15, 4064 or Varget, about 30 grains, putting a Walters .360"x1/16" card wad in the case neck under the bullet, compressing the powder slightly in final bullet seating and crimping. Velocity is about 1600 fps in a 20" barrel.

7.8 grains Bullseye, 1094 fps, 11 Sd
8.4 grains Bullseye, 1234 fps, 18 Sd

That is awesome.

Howdy !

For a rimmed .35 caliber wildcat ( long, straight taper w/ a straight neck section ), some candidate " parent " cases are:
.220 Swift
- .225 Win


A rimless case that could be utilized w/ a section of " moon clip ":
Case Base diam Rim diam Case lg
- 5.45 X 45 Soviet .394" .394" 1.560"

This is same rim diam as 9mm automatic, and " moon clips " are available for these.

By way of comparison, .357Mag/Max are listed as having .379" case width @ the case mouth. .35 Rem is listed as having .384 " neck OD.
A notional .010" case taper would be about the same as that utilized w/ the " 6PPC " case design.
With .394" base diam and notional .384" case OD @ the case mouth end, this wildcat would have some .010" of case taper ( and around .013" neck wall thickness )

A more exotic .35 cal straight-walled wildcat:
Case Base diam Rim diam case lg
.224 Weatherby brass, cut-off .416" .430" 1.482" case oal ( double radius section of case cut-of ).

This wildcat would headspace on the "belt" of the parent case.
While shorter than a .357Max, this wildcat's larger base diam would keep case capacity same as or slightly > .357Max.
Bolt face could be 6.8SPC-size ( " PPC " ) opened-up approx. .008".


FWIW:
I've been experimenting w/ .35Rem " neckless " ( .35Rem w/ neck cut off ).
Case oal is around 1.623".
Bullet used is " Dead Center Duplex " swaged 195gr Spitzer Boat tail ( rebated ), taken from .45 cal saboted muzzle loader 12 pac.
Bullets are " patched " w/ Nylon " Dymo " label maker tape.
Bullet body overhang above the rebated boat tail mates to flat case mouth opening. Gas sealing is accomplished by closing the lever, where upon the bolt
in " battery " forces the bullet up-into the rifling; which also forces the bullet back against the mouth of the neckless case.
The 195gr swaged bullet is a great fit for this particular " breech seating " project.
Lever/bolt closing effort is not much more than what is normally felt when shooting stock (necked ) .35Rem loads.

Outpost, thank you for sharing your wildcat. That is a very interesting 35 caliber.

I was first introduced to this round by the late Roy F. Dunlap, NRA Board Member and noted gunsmith of Tucson, AZ.

When rifle silhouette shooting first took off, in the 1970s, a bunch of fellows at the Three Points range wanted to use cast bullets and the .30 cal. cast bullet loads didn't have enough "muscle" to knock down the sheep targets at 500 metres. Alot of the guys were using Remington 788s because they were accurate all out of proportion to their cost and had good triggers.

Paul Marquart was reboring shot-out .308 Remington 788s to .358 Winchester with 12" twist, firing 260-grain gaschecked bullets designed by Richard Hoch in Colorado. My LBT bullet is based on the Richard Hoch design, but in plainbase configuration.

A few fellows came up with .30-30 Remington 788s, and Paul rebored those to .35 as well, and that is where the .35-30 Marquart came from. In a strong boltgun you can fill the case with all the RL7, 3031 or 4895 it will hold and get about 1800-1900 fps on a 260-grain bullet, which had enough impulse to take down the ram with a low body hit.

The fellows who hunted the area north of Prescott around Humphrey's Peak found it made a good mule deer and elk rifle in the high conifers as well. Recoil from the rebored .30 cal. factory barrels was sharp with the heaviest loads, but with the 260 at 1800 fps no worse than firing a 700ADL in '06 with factory loads. Many of the pure target shooters often put heavier Douglas No.5s on their silhouette rifles to beef them up to the 10 lb., 2 oz. weight limit for silhouette.

Joseph B. Roberts of the NRA staff had Paul do him a 94 Winchester in this caliber and he killed alot of game with it when he was a guest in our camp. In the 94 Winchester a caseful of 748, 4064, RL15 or Varget does the trick and keeps things simple.

Another option for a wildcat is blowing the 5.56X50R case straight, essentially a 357 super maximum. Years ago I'd contacted Starline about making a run of such cases but they said their tooling couldn't produce a 2" 357 case.

The most practical based on available brass would be the 35/30-30. It would be outstanding in a single shot or svelte double rifle.

Why hasn't someone mentioned the ancient "35 Winchester"?

35 Winchester is a bottle neck cartridge.
