Default Anybody ever converted a Marlin or Winchest

Advocate,

With regards to my .30-30 Journal, I am finished with the first 4 chapters
(1891-1895, Cartridge Development At Winchester; 1895, Introduction ; 1895-1904, The First 10 Years, and 1905-1927, The Second Generation).

I still have about 3 chapters to go, along with a section on reloading which will primarily deal with replicating all of the factory loads ever offered for this cartridge, from the Special 85 gr. Full Patch Peters load up to the heaviest, a 180 gr. loading. All in all, about 18 different bullet / velocity combinations(!).

If I could concentrate on finishing the project, I would hope to have it to the printer by September, but since I can only work on it off and on, I will be lucky to finish it by year end.

The good thing is that my research appears to be complete with no new information being uncovered in the past 12 months or so. That should help since I spent a fair amount of time on research in the past.

Thank you for asking and for your interest.


Graycg,

Good luck on your project. Please keep us posted on any further developments.

Why not rechamder to the .360 Dan Wesson instead ? It's between the mag and max in length.

rob applegate did a 475 linebaugh on a 94 marlin for me. How does the length of a 357max compare?

I tried some 357Max dummy rounds in my 336 last month. A single round would feed from the mag and almost chamber except for being too big in dia. With two rounds in the mag both would try to feed and it would jam. Those were with 158gr XTP bullets with a COL around 1.9". I'll have to try some heavier bullets like the 200gr Lee or sierra 200gr rn at around 2.2" COL to see if they are long enough that they don't jam or if it's more of a rim diameter issue and the feed latches just not catching the second cartridge. I'm sure there's a way to adjust for COL in the feed system, but I haven't taken mine apart yet to see.

Never seen a 475 linebaugh but WIKI says the COL is 1.77" which is a little less than what the 158gr COL is at around 1.9". I'd want to use at least 180gr and if possible 200gr cast in mine so the COL would be closer to 2.2"

Rob told me the 475 was borderline to long for a 94. I have to use short in the nose bullets in it. So I doubt theres room for a 357max. He also said about 35k was max pressure for the 94. Now ive run a bit higher then that without trouble but sure wouldn't push it past 40k. So what I basically get is 480 rifle performance using 475 brass. Its nice when carrying both the handgun and rifle to be able to share ammo but truth be told a 92 rossi 480 might even be able to be loaded faster then my linebaugh.

Some of us are limited to straight walled cartridges due to hunting regulations or I'd just use my 336 in 30-30 as marlin had intended. For now, it just sits in the safe unless I go to my buddies in MO or sisters in WI. Rebarreling it in 357Max wouldn't give up a whole lot and would let me hunt with it more frequently. My 444 marlin is in the same boat, but I'm playing around with cutting a few hornady cases down to 1.8" (longest a straight walled case can be in my hunting zone) and seating the bullets out further. Don't think It'll ever match my 444 loads but at least it will get used again.

Maybe these guys can do it. Expect to refinance your house to pay for it though.

Now I know its not what you want to hear but I have a 35 remy 336 in blue and one in stainless. and if it weren't for that I might want a 357 max. The thirty five rem is better than a 44 mag and can be loaded down and shoots a 200 gr. nugget that will stop anything a 357 max will.

or else...................
