Ultralight Custom Break Action Rifle

[left hunter]

Yeah, I’m gonna try to not throw anything but time into mine if I can help it! Any idea what your action is made from?

 

[Trackselk]

I can see the case fitting the chamber for multiple firings, my neck sized brass cases usually fit for several firings. My question would be about maintaining neck tension over multiple firings.

I wonder how well a neck sizing die would work with them(??). I also wonder if they'd start popping primers at those higher pressures. Certainly might open up some different reloading angles with powder choices, etc.

So, the guy at Phantom said the neck tension was more consistent, but I didn't think to ask about neck sizing, your neck size only idea is a great idea!
He also said the primers often don't show pressures until you're waaay over pressure, like 100k+, so I think the pockets are a non issue with the 2 piece design.
@ACHILLES He also said no problem with the SOLO300 bolt. I'm thinking of shooting for 70-75k so the cases last much longer, but the wear on the rifle sounds like a non issue. Still getting many thousands of rounds through gas guns...

My 5.5 lb including everything 308 was pretty rough, a 5lb 12 gauge, wow, probably like those cheap single shots I shot as a kid, not fun.

Have you fired this ammo and had fired brass to measure or test for chamber fitment? Or are you just speculating.......

 

[Trackselk]

Something about the design of the cases is what should make the difference. The case is taking the extra pressure, not the action. Same idea as behind the new "7 Backcountry" cartridge id guess.

if I remember correctly, Mike Bellm told me 223 was on the edge of what the contender frame could take. It was pressure/ rear thrust related, so I wouldn't even try 5.56 pressures, but I could be mixed up as it's been a long time.

He's just thinking about potential problems. I did order a box last night, so I'll have some of the magic brass soon!

 

[Long Cut]

Ouch! That's all I have to say.

I will only shoot reduced power 2 3/4” shells through this gun. I have a TSS load coming in later this month for it.
A full power 3” would absolutely suck

It says on their site that you shouldn't resize the rifle cases.... Have you found anyone on the web resizing them successfully? No trimming sounds like a dream

I have a 12 Gauge that looks quite similar. Mine seems to be made out of fairly heavy steel.

Nope, but I tend to run my loads hot enough to wreck alpha OCD brass in about 4 reloads anyhow. I won't shoot them much, shoot cheap factory stuff for practice so a box of 50 will last a decade or more if I can get a few loadings out of it

Just to add to those interested in the contender variant. For their finished weight and compact size they are solid. Mine shoots very well and has the nickname Swiss cheese. Its currently 5.4lbs all up suppressed after changing rings and rail recently.

Are there any optic mounting options on that barrel?

 

[Matthausarchery]

Yes it has the SSK 6 screw mounting holes but I use a weaver base and warne hyperlite rings now. Over the ssk mount and pervious rings I dropped ~3oz from this which did not include my sling or 1 223AI cartridge.

That's still a chonk of a barrel contour, even if it is fluted. Will they do a proper lightweight thin barrel for a T/C frame?
Sub 4lbs on the bare rifle. I think you're pretty much there. What suppressor is that?

Is yours super sensitive to face pressure? Or just pressure points in general? Mine with the 6 arc barrel is wildly sensitize (like 5 moa). I’m wondering if it’s the folding AR style adjustable stock or something else.

It's all about the hinge pins. You want them to be a light press fit, for action and barrel

 

[Loper]

I ordered one of these last night. I’m not claiming it’s an Ultra light but I’m intrigued to see what it actually looks like and weighs on my scale. The specs say it’s an aluminum receiver. If so it might be possible to get this gun pretty light with some work. Either way it’s cheap so I’m not out a ton of money either wayView attachment 820091

What rifle is this and where can I view more information about?

It’s actually super tight for the barrel that doesn’t shoot as well. My .223 barrel is shorter and lighter. It’s pressure sensitive but we are talking 1 moa. If I do my part it’s easily a 3/4 minute barrel.

 

[Matthausarchery]

Mine is very accurate without too much thinking about it. I am using the oversize hinge pins and relieved the forearm stock so it only makes contact where the two screws mount. Both forearms screws are torqued equally and the mounting dovetails are slightly loose before mounting the forearm. Ive done this with all my contenders. My SSK 6arch chamber is slightly oversized, when I resize the brass I barely touch the shoulder. This tightened up my groups.

It is the standard contour (straight .810”), Karl really got after it with the fluting but it isnt as light as it could be if it was turned down. A 5 axis machine could turn it down and leave the forend mounting dovetails. I would guess a pencil profile would be around 16-19oz. But smokes you would have $$$$ into it by then.

It is a banish 223, I really like it.
