I'm still trying to decide what I want to build this pristine Martini action I bought, into...
as I was shopping for component availability... I found a good deal on a 375 barrel... got me thinking about 38-56 ( a cool old cartridge ) but then I also thought about the 375 JDJ... with this Martini, I need to keep the pressures "sane" but the JDJ is chambered in Contenders, so it would definately be safe in the Martini... also need a rimmed cartridge, so the JDJ again would work well...
I was originally leaning towards the 7-30 Waters, but don't want to mount a scope, ( actually thinking about machining it for a rear mounted "tang" sight... so I'm thinking bigger, shorter range, thumpers... the 38-56 is a 45-70 case necked down... the JDJ is a 444 Marlin case necked down & more efficent design... one concern with the JDJ might be the straighter case body, might make ejection tougher in the Martini design... the 38-56 would eject easily
any of you guys shoot the 375 JDJ... what can you tell me about it??? how is the extraction??? sticky cases at all??? I see Redding makes a 375 / 444 die set that is available, & the comments suggest it makes great JDJ cartridges, so the dimensions must be the same...

I have a factory G2 23" Carbine in 375 JDJ. Cases are easy to form and it shoots a 220/225 grn at 2500 fps with pressures allowed in the Contender. It is great for deer thru elephants with the right bullets.
Operates in the low 40,000s. Extraction is pretty much tilting barrel up. Case life unlimited if chamber is cut tight.
Dies probably a bit cheaper directly from SSK.

I've had a 12-1/2" barrel Contender for 26 years that I've hunted on 4 continents with, taking animals that weighed less than 25 to more than 2000 lbs. I also had a 15" Encore for about a dozen years. The cartridge is superb in an SSK barrel; accurate, powerful, and easy to load. I never had any problem with it, and highly recommend it. I never used any bullets other than the 220 FN and 270 Spire Point from Hornady, and never found any reason to try anything else. I don't know anything about the strength of the Martini action, but extraction should not be an issue with a good gun.

I shoot and load the 358 JDJ and love it! Easy to load and hammers deer. Will take elk hunting this fall.

It is my understanding that there has been more than one SSK spec on this cartridge since introduced. I'm sure that if SSK did the custom work for you then your SSK dies would match. However the Redding dies, quality that they are, could possibly present a problem based upon how the chamber was cut. While I have and use the Redding dies as well and can attest to their quality, my chamber was cut using the dimensions from the dies themselves.

What about the Reeder 375 GNR#2...It's based on the 45-70. Not sure of pressure numbers but I'm betting the Martini action could handle it fine.
Plenty of brass and bullets available and the 260 Accubond is a great shooter and hits hard on game.

that's a good possibility as well
I'm thinking I might revive the old 38-56...

Read some of JD Jones' writings on pressure.Because he was usually dealing with the Contender his concern was frame stretch due to case head thrust. Maybe the same with the Martini.The more tapered cases are harder on a Contender than the less tapered or straight sided ones.He said 30-40 AI was easier on a Contender than a regular 30-40 at lower pressure.So the JDJs might be a better choice than the tapered 38-56.I may be off base as I know little about Martinis but the OP mentioned extraction.

I have had a SSK barrel chambered for the .375 JDJ in a TC Contender pistol for several years. I will say, that it is at my upper limit for recoil in a handgun. However, when I got it I made up my mind to get GOOD with it offhand. My best target was on the 25 yard Timed Fire target. I shot ten shots and it scored 100/10X. I felt pretty dern good about that. However, I have never shot any deer with it. Ohio doesn't permit bottle necked cartridges for deer. I will tell you this - it would DEFINITELY do the job and then some (based on my experience with deer using a .44 magnum). I also wouldn't hesitate to use it for Black Bear hunting, either.
Never had ANY problems with ejection in the TC Contender.

the last 2 posters are what have me interested in possibly doing the 375 JDJ

Rather than talk you out of one, the intent of my earlier post was just a caution. If memory serves the purpose of the spec change was to blow the case walls out a little straighter to benefit the break actions it was being chambered in. If it makes sense in your set of circumstances then by all means do it.

Magwm I've had a 375JDJ of one flavor or the other for the last 20 years. First one was a 14" SSK Contender bbl and it was a dandy. I had to have one after reading "Hunting for Handgunners" by JD Jones and Larry Kelly. The other was a 15" Encore but I didn't use that one at all. I actually got it in a trade. It just left the stable and it's new owner is a member here. BigBore44 PS If you haven't read the book I mentioned above, I Highly recommend it to anyone who is into handguns and handgun hunting!!!!
