Well this thread so far has lead me to a Contender 14” barrel in .375 JDJ with some correct headstamped brass from a kind member here and an easy open blued frame with a Pachmayer gripper grip and forend. Now to decide on a scope and have to get dies If you need more brass forum.accurateshooter.com/threads/hornady-375-jdj-brass.4063712/

As I munch popcorn,, my hands start a little twitch,, and my mind is oiling the gears. The idea of a 7 TCU has been in & out of my feeble mind more than once. I've resisted getting one more than once. (I'm a 7x30 Waters fan.) But I my gears engage my radical thinking part of my brain and keep telling me; "You should try one!" So, maybe I should get those dies, (cheaply) from Encore64,, and let that be the seed that grows into a 7TCU barrel for my bunch. ***** Tyrone.... Wes Ugalde’s 7mm/.223 with 40-degree shoulder produces tournament accuracy from its fire forming load. No such luck with many “improved” cartridges. Take new .223 brass... wet a Q-Tip with Brownell’s Dry-Slide (moly-disulfide in evaporative medium)... lube inside neck... run case over a .22-to-.284 PROGRESSIVE EXPANDER... seat a 140 to 160 grain 7mm, slightly long, over 24/H4895... And then, start nailing targets. Flat base bullets are preferable to boattail in T/C barrels; more accurate. Boattails are more bore-sensitive. Jeff.... the .30-30 Winchester is based on the .30-30 case and, like the 7mm TCU, is easy to load and for silhouette shooters worked well in 10” barrel as well as 14” barrels. Just have ear muffs and dark glasses when you stoke the .30-30 with Hodgdon BL-C2! David Bradshaw

I've never shot Silhouette with Contenders or anything else. So, I'm unable to speak on the Subject. But, have experimented with load development since my teens. Had an older cousin who did shoot Silhouette and he is responsible for getting me started.
I have hunted everything from Prairie Dogs to African Game with them.
JD Jones and I used to discuss much about these guns. Mostly on Sundays as he was usually there alone working on his next project. I still consider him the foremost authority on Contenders. He used one single frame to develop every cartridge he introduced on the 444 Marlin Case. He told me he kept it as evidence that the larger cases didn't damage the frames. Almost 50 years later, some are still convinced the larger cases will damage the frames. When that stuff is written and read, some people can't move past it regardless of the evidence that proves otherwise.
Right now I'm waiting on a 12" Stainless Bullberry Contender Barrel in 45 ACP/Auto Rim. Troy tells me the extractor can be cut to work with both cases.
I had him give me about 3/8" Freebore to reduce pressure and allow flexible bullet seating.
Starline says their 45 AR Brass is built to the same strength as their 45 Colt and 44 Magnum Brass.
I believe modest loads of suitable powder will produce 44 Magnum Revolver Ballistics...

That link to 375 JDJ brass would be more tempting if my barrel weren’t chambered marked as 375X444. The reason I raise the subject is because several of my barrels are made by a lesser known custom maker from New Hampshire: On Target Technologies or more commonly OTT. What was unique about their barrels was that they were chambered via a patented EDM process rather than using a reamer and a lathe. With no reamer being required you can imagine a minor wildcat explosion occurred at the time. Conversely have you ever run into a situation where your reloading dies didn’t match your chamber as well as you would like? I provided a set of Redding 223AI dies, a CAD drawing was created based on their dimensions and a chamber was “burned” into a PAC-Nor blank which was the basis for a Contender barrel.
Yeah, lots of Contender “factoids” are fading away as the years go by. Sometimes I want to say “thanks for nothing” in S&W’s direction but it is more than that. It is easily as much the world itself can no longer embrace the concept of a single shot firearm in the year 2023. Good thing for forums like this!

The 375 JDJ has a really long history. Some adopted different names because you can own a name, but not a design.
It's always been funny how this works to me. When some manufacturers do this, others clammer about people stealing their idea.
As far as I can find, the 444 Marlin was necked down to 375 Caliber by Ken Waters in the late 60s.
He called it the 375 Express. It was created to breath new life into a vintage rifle.
My Dad always said there was nothing "new" following the 8mm Mauser. It's hard to argue that point.
Custom Barrel Builders have cried foul for decades when somebody builds something similar to what they do. It's almost laughable since everything is from reformed production brass.

I keep thinking about Gary’s wildcats based on the .204 Ruger Ronnie, I have something you may be interested in. I just don’t have time to do anything with it. Shoot me a pm if I’ve stirred your interest😜.

This thread is costing me a lot of money because of the great deals I have been offered. I will have the ultimate Contender battery to hunt everything from varmints to pachyderms!

They can sure be addictive. The Contender Carbine is possibly even more so than the pistol configuration.
I started with Contenders about 1978 or 1979. In the 80s and 90s, I shot them a lot.
Remington Bulk Bullets were dirt cheap and Midway USA had free shipping in those days. Hundreds of rounds a weekend went down range. I'm sure the neighbors were not happy, but never had a complaint.
I'll post about what I've learned, but no longer argue the point of strength. But, I've proven enough to myself.
Probably 30 years ago, I had a 7.62x39 Barrel built. Was told the head diameter, case taper and pressure would crater an action in short order. Thousands of rounds of full powered loads later, not a single problem.
As posted earlier, I've seen one frame stretched to the point it wouldn't function with 7TCU. Saw one barrel blown to shreads that was chambered in 357 Magnum. Story was a guy picked up Win231 instead of Win296. It was on display in a gun shop and all I have is the story I was told...

I still kick myself for getting rid of my 6.5jdj. Need to get another frame and get a barrel chambered in 10mm and another in 45 acp. Dont knw if possible but a 6.5 grendel barrel on a g2 frame would be a close match to the jdj with factory load options. Yall gonna make spend more money.
