Are you considering nitriding the barrels or is the expense to high for a disposable item?

Hi,

We are not really considering it at all; not because of price but because Nitriding should not be used as an "aftermarket" thing.
There is just way too much that can go wrong.

Barrel MFG A uses abc alloy and heat treats at xyz temperature.
Barrel MFG B uses hij alloy and heat treats at tuv temperature.

One could nitride with no problem and one could become a "liability" real fast due to nitride temperatures vs heat treatment temperatures.

We have no desire to chase down alloy certs and heat treat certs for every barrel from every manufacturer.

Nitriding should ONLY be done by the manufacturers and nobody can change my mind on that, lol....

Theis

At least you know the difference between a taco and a burrito...

You're prolly gonna need to straighten out that fella that likes the blue and white soccer team.

Or is it white and blue?

You dressing the part or just bringing the rifle?

Hi,

Definitely not dressing the part. Do you know how many Star Wars junkies there are in the precision rifle world......They would all be asking for autographs and checking out my butt instead of the rifles.

Hi,

Well, first things first...
The top half is white on blue while bottom half is blue on white...now onto that taco and burrito thing.....What would a fried burrito then be called based on the "soft vs hard" as the differentiating criteria as outlined?

Mexican food is as confusing to me as Mexican language, haha

Chimichanga=fried burrito.

Tostada if you're lazy and don't want to roll/fold it. 😂

Half-assed, folded=taco.


Then there's "Mexican pizza"....

I'm still cornfuzed about this soft shell stuff too.
I was under the impression it described a blue crab during the moulting phase that got caught, fried and placed into a bun.

I think it becomes a sandwich, but you might wanna ask that flopper watcher fella.

Hi,

100gr 6CM PVA Monos doing pretty good so far :)

Now let us see just how fast we can push them with the mindset of single use brass, hahaha and since we can load them as long as needed in the 3.85" CIP magazine; it should be fun 😁

Hi,

That target is from a 7 twist.
Will be testing 8 twist this weekend.

@THEIS would you be willing to share load data once you ship out some rifles? It would be nice to start right there to save on hard to get components

Hi,

Not sure you are going to want our final development loads unless you agree brass cases are consumable, lol...but we can assist with some normal load data for sure :)

Maybe with all the people getting ready to walk off or get jab fired; someone will setup a polymer injection molding company specializing in injection molded cartridge cases....

I've sent several barrels (K&P, Krieger, and Rock Creek) to Parker Trutec with zero issues (none of them asked for certs). Since nitriding is done after chambering, the only way you are likely to get a barrel from the manufacturer, already nitrided, is by getting a pre-fit. Me...I've only had one barrel that was a "standard" chambering (thus a possible pre-fit). Come to think of it, I've never seen certs for a blank nor noted the option to get certs. Its not like you are buying a chunk of bar stock.

I remember back in the day when nitrided and tufftided cranks were a thing.
Click to expand...
I deal with nitrided crankshafts a lot... and after grinding... they have a tendancy to warp as stresses come out of the forgings... held in place by the nitriding which can act as sort of an exo-skeleton.

It's a process that proved great in lots of places. Not on cranks!!!!

Hi,

O MY!!! 3D printed 15-5PH 300NM cartridge cases finishing up the post printing operations. Surface finish of the ID of the neck is around 24 Microinches.

Betting primers pockets are able to handle more pressure without "blowing out", lol.....

Theis,

The outside of the case and the neck ID are machined, is the rest of the interior of the case left in the 3D printed condition?

Do the virgin SS cases use the same dimensions as brass cases? I’m curious in the difference between SS and brass when the case expands to seal the chamber upon firing.

Interesting... what material are these made of? How are the prospects for expanding and sealing the chamber when firing?

Make sure it's a beater and stay far away just in case :)


THEIS said:
Hi,

Material is 15-5 and based on the case thickness, etc there should not be anything that would lend itself to improper sealing...but we will definitely have to see what happens when comparing theory to dropping firing pin onto primers.

I saw a different video from Alpha were they said quickload estimates were at 80k or so during their OCD testing 🤷‍♂️

Hi,

That is pretty awesome!!!
I don't really follow either of those channels; their QL estimates were based on Orkans' test firings?

Here are some estimated pressures from Petersen too..

22 Creedmoor Load Data

Since its’ inception, in 2007 by Hornady, the 6.5 Creedmoor has seen some pretty meteoric growth in popularity. That growth continues as of this writing, as the cartridge has now gone mainstream with hunters and shooters alike. As the popularity of the 6.5 Creedmoor has increased, so has the...

Probably why they aren’t promoted as much anymore.
Probably have better processes available now as well.

Hi,

I cannot get the pressures and MV to match up in Gordons Reloading Tool even using Orkans 22CM specs on his website. To get that 3700fps MV it shows more like 46grs of 4350 to get to 74K pressures.

Disclaimer...that is purely software simulations!!

I have no idea what they're using, it's interesting but I'll let someone else test this first. Your engineering and the material used for hoplite are definitely cutting edge in what you're trying to accomplish.

Went back to find what they were saying... Orkan 22CM 4.15 of 4350 with 75eld-m and the other video had a 22GT with 78TSX 40.1 of 4350 at 81kpsi.

It’s all about bolt thrust.

Cases will come and go but the bolt/action lugs need to be up to the task.

you can put a “super” case in a “regular” action and the case may look fine but you compressed the bolt lugs past their elasticity…bolt set back. which caused subsequent issues that just keep building

or even worse bolt lug cracking and finally lug sheer which we all know is bad

Hi,


But if I shorten the COAL from what he has listed at top of the page to the length he has listed further down the page with load data I get something more like this..

DISCLAIMER: I am definitely not the ammo reloading guy so I damn sure could have a number out of "tune" somewhere.

Hi,

Good for you!!!???

Let me know when your product liability insurance is 4k per month and we can discuss what you are advised/allowed to do with another companies manufactured product and still be covered.

Hi, Theis:

I very much respect you and your efforts. That noted, bashing tech that is a very well proven and very well accepted does no one a service. As with every process, the processor/processing is where the rubber meets the road. Do you seriously have grief with folks like H&M and Parker?

Liability insurance...as you already know, your bills (for the insurance itself and the associated legal support) are REALLY going to spike when those day-one-promised Hoplite rifles, in "Hoplite Arms High Pressure" chamberings, start shipping. Hopefully you are going to flat state that the associated Hoplite, single-sourced "brass" are not to be reloaded and that your high-pressure-capable rifles are not to be used with other than Hoplite factory ammo. That the plan? And Hoplite factory rebarrels only, correct?

Peace brother! Not trying to rile you up. Hope you don't take my comments the wrong way.
 
#3,598
@ELR researcher I'm not going tonspeak for Theis regarding Parker and H&M.

But when it comes to liability, Hoplite has said they won't share load data for those crazy pressure loads, nor do we have the components to survive his testing. Hence his custom 3D printed cases.

What he is doing is not settling for the industry standard, someone has to make changes and pioneer break through in all aspects of life. Look around we see the envelop being pushed everywhere.

I understand you're trying to give a heads up, which anyone would agree with, so take my response in that spirit.

I personally am stoked to see someone making these changes and I want to support it. I missed my ban wagon with solar in the beginning and bitcoin. My stupid way to make up for it. 🤣

Hi,

LOLOL I have not bashed anything. I said NOBODY is going to change my mind...including you, lol.

For every place you can list that will nitride for the end user level I can list 10 that will only do so for the OEM.
Of those 10..ALL will require alloy and HT certs.
