google 35 gibbs. Too long for a Marlin action, but I imagine the shoulder could be pushed back to fit.

Edit: corrected below by Tinker Dave...Greevy Express, not Gibbs.

 

I suspect a .45-70 necked to .35 would be interesting but to what end. You are looking at custom dies ($$$$$$), a barrel job ($$$$$) and perhaps some action work to make it feed. In the end you are still limited by the pressure limits of the Marlin action. A .356 Winchester chambering will give you all the zip you are going to get from a .35 on the 336 platform which is a bunch and way cheaper.

 

When one starts dreaming of cartridge niches yet unfilled, it can be loooong morning. ;~`)

In the bigger bores, it seems to me that there is pretty good coverage lately, what with the .356W mentioned above & .338 Marlin. Regan Nonneman's experiments with a hot loaded .38-56 certainly has stretched some parameters, Tho it's been a couple of years since i spoke with him about it, IIRC he was featured in a couple of sporting magazines and wrote up some African safari/hunts with his guns.

In the sub-.30's there is still that niche of the 6.5/.257 that gathers dust. The XLR model would seem to be a suitable home for such a critter. On the old Marlin board there were a couple of discussions about it. Some pressure/bullet weight/velocity/parent case parameters were worked out with a ballistician in Alaska, which results Nonneman felt were quite within the 336's pressure limits. Think of a lever action-suitable 120gr .257Roberts or 140 gr 6.5 Swede. Tomray may have carried that discussion back to Marlin, as at the time there was quite a bit of internal corporate interest in new proprietary cartridge design going on.

Anyway, as the foregoing demonstrates -- just mention NEW cartridges and the pet-project suggestions will emerge from hibernation everywhere.

 

Isn't the 375JDJ a 444 case necked down? Maybe there's a 35JDJ that could be made.

JD runs his pressures pretty hot. Not sure about their suitability in a 336. A scoped Contender handgun in that caliber, tho, is a hummer for turning water-filled milk jugs into spectacular mist explosions at one hundred yards.. The owner said it did a fine job on Michigan whitetails, as well.

 

Hey there Oberhaz...as far as wildcatting goes, it's not always what you need, it's what you want. I say if your pockets are deep enough go for it. The .358 caliber certainly provides plenty of bullet selection to experiment with in new cartridges. I don't know what your intended uses are for your new brainchild, but the 336/1895's do have some pressure restraints to consider. If that pressure cap doesn't effect your desired performance level I say bring it on....I'd like to see the results.

 

Well it's been a long road (2yrs) for my 375 JCC-Marlin wildcat based on the 338 RCM/Ruger case & 450MXLR. The gun is back from Nonnemans & the first loading trials look very good. 220gr. Hornady at a chronographed 2549fps from a 22" barrel. ;D The 250gr bullets should hit 2350fps.

A 35 JCC-Marlin would push the 220 speer to 2500 also. I was going to do a 35 but went up to 375 cal because I have a 356W already & the new 338MX is just too good & too close to 358. The 375 JDJ is too long for the marlin action. The 375 JCC fits like a glove. I might build another one.

It does cost some money & time to build a wildcat. On the other hand............Ya can't take it with ya!!

I'll have a new thread for the 375 JCC in the next couple weeks as I collect more data.

I was wondering, what if Marlin produced a .35/70? I really like the 35 Remington, but have often consider going with a .45/70. I don't really want one, there's something about a .35 caliber that I like.

I realize there are other offerings, .358, .35 whelen, etc. Perhaps theres no need for such an animal. But the thought of it sounds pretty good to me.

What do you think? Good idea or bad? Don't be shy, I can take it if you don't like it.

How about one with a big loop/ Guide gun set-up?

It has been done. It is called the .35 Greevy Express - look it up! TD

 

Could be a interesting thing

 

I can modify a Marlin action to accept a COL of 2.750. That being said, you must keep in mind that the pressures of any cartridge used in a Marlin must have its limits. I believe that the 375 Winchester (somebody correct me if I am wrong here), was chambered in the Marlin levergun, and pressures were up around 52,000? If my memory is serving me that was a straight wall case......add a shoulder and everything changes.

 

.348 Winchester?

 

Swany; I think that was it!!!!!

 

Reaching back to that 257ish type round in a 336. 25-35 Improved was on the tail of the Roberts. New bullets & powders would be very interesting.

Flat Top I have one of those M-375 in 375W caliber. Yeah they Do exist. And I'm pretty sure the working pressure is as you stated.

A 35-70 would probably NOT give you any advantage over the 356W. And it is almsot up to the 336's pressure limits. Now a 257-356 sounds mity interesting! ;D

BTW, guys remember that any standard or wildcat caliber in a LEVER gun is limited to the flat point bullets. Take the 35 for instance...yeah lots of 35 caliber bullets out there but most of them have POINTS. Not a good thing on guns with more recoil.

There is a fine fellow from Aussie Down Under that did quite a bit of work on .25-35 potentialities, along with - I think - an American cyber-sidekick. Can't remember which board they used to be on -- 24Hour or Accurate Reloading or Leverfuns? Pretty sophisticated, in terms of quantifying their work. As well, Paco Kelly's writings are always worth a review when it comes to lever-loads.

Anyway, they were pushing the AI pretty hard, and IIRC found that there were some unexpected and suddenly sharp parameters as to how far the Imp could be hotted up. Wish I'd kept the data handy, but someone here with better memory might be able to cite their present whereabouts. They did turn out quite a bit research, and anyone interested in the IMP may find it good reading.

 

Now a 257-356 sounds mity interesting! ;D...... limited to the flat point bullets.

That does sound like it has potential. Is the case volume based on a .308Win sized cylinder? I apologize for not having the time I used to look up tech-stuff, as I like to check it out before I run off at the keyboard.;~`) I do remember the ballistician involved with the project searching for a parent case w'a larger diameter than the .444/.30-06 cylinder, for a variety of pressure/volume/wanted velocity reasons. A .45-70 case came closest to the desired performance, but was still shy of the near-3000FPS desired for the bullet weights. Nonneman felt the .38-56 case was most suitable.

Also,that was all about the time the gummytip bullets were being introduced, and the idea was that if the round would become 'official', then suitable 'lever bullets' in factory loads would be the corollary. I guess that's about what I remember from this trip down memory lane. It as also wandered quite off the original poster's topic. So, mebbe as a courtesy, and if anyone is interested in pursuing it, they might want to start a new thread on a .257/6.5 lever-cat.

 

25-35 the 356W case is a 308 case necked up to 35 caliber and also given a rim. So i'd guess it would have close the same volume as the 308 brass. You could do th esame conversion with the 358W but it is NOT rimmed for lever guns.

T-o-m

 

Isn't the 375JDJ a 444 case necked down? Maybe there's a 35JDJ that could be made.

There is a 358 JDJ based on the 444 Marlin case. I have a 375 JDJ and it is something to shoot in a Contendor pistol...

336ER in .356Win..... good luck finding one ;D

 

444 necked to 358 & sized for a marlin action IS the 356.
