How many really want a NEW 9mm bolt action carbine?

[jdne5b]

In giving it more thought I now realize that the non-NFA 16.5" version will be shooting everything from 90 gr. to 158 gr. factory loads.
The NFA versions would want to be optimized for heavy sub-sonic rounds.
This might change the twist for 16.5" barrels?

I don't know why a 1:10 wouldnt work for both. Looks like most 9mm AR's are 1:10 twist, short and long barrels. Pistol barrels are 1:10 to 1:32, with 1:16 being almost the standard with some 1:10's scattered in the non-1911 market.

[Richard/SIA]

Just bought two more TCM's to convert to 9mm.

If anyone has a configuration they would like it's first come first served.

[Richard/SIA]

Should be getting TCM actions and barrel blanks in this week.
Spent some time loading 9mm 125 gr. sub-sonic rounds for testing.
Now realize another advantage of bolt action over semi-auto.
You can load light rounds for pest control or plinking that would not cycle an autoloader.

[Richard/SIA]

TCM's finally came in today.
Going to do one as an SBR and the other full length, 1/2-28 threads.
1-10 twist rate as that is the easy blank to get.

[Richard/SIA]

Better pic, with the first SBR to be completed.
Also put a De Lisle type fore-end on the suppressed version to clean it up.
Next up is fitting some sights and completing a full length barrel example.

[diablito]

Looks great... The De Lisle fore-end looks great (imo), really ties the stock together. How about a vid of sound and cycling.

[Richard/SIA]

Taking video, trying out a screw-on can or two, and some informal Db. test are scheduled for Saturday.
Hoping the wind will not be too bad.

De Lisle fore-end is a flawed one I had laying around.
Could make them an option if desired but I'm trying to keep these simple for quick delivery.
The only way to get a good color match would be to paint the wood.

[Richard/SIA]

Back from the range and very happy with the Novem 9mm's performance.

Just enough wind that the Db. meter I had could not get a reading over the ambient noise.

My integral unit is very quiet with subsonic rounds and still excellent with supersonic.
The barrel is not ported to reduce velocity but is ported to the expansion chamber starting 5.5" from the chamber.

Got to try the Novem SBR with a couple of big name screw-on cans.
Not quite as quiet as my integral but close with sub-sonic rounds.
With supersonic rounds the advantage of my integral unit was clear, probably due to the extra volume.

Also shot the Novem bolt action against my own semi-autos which use the same suppressor design.
All semi-autos actions have an inherent disadvantage as noise from the chamber and action are significant.
My conclusion is that if you want the absolute quietest shot you MUST have a closed breech action like the Novem!
The difference is clear and substantial.
My integral Novem may be even quieter than the De Lisle, but I need a calm day to verify that.
Of the semi-auto's the Thureon action is less noisy than an AR type.
The 300 BLK is pretty quiet but the integral 9mm Novem is the champion of the day.



Also shot some 9mm pistols and Tavor .223 and 9mm's suppressed, Tavor is not a quiet action and plastic furniture may be hurting their performance as well.
The .223 Tavor (supersonic) was too loud for me want to shoot it more than a few rounds without ear protection.

I would like to see this in a 8-9" barrel, threaded 1/2-28 for most 9mm muzzle cans, and a permanently attached shroud a la the tacsol SBX barrel to accomodate a 1.375 9mm muzzle can and bring the OAL to 16". I imagine this would have a larger market than an integral as it could utilize the customers existing 9mm can. I would definitely be in for $800-$1400.

The suppression of muzzle cans is so good (e.g. aac Tirant) these days that I don't see that an integral would gain all that much.

Will have the first of these complete in the couple of days.
9.5" barrel and 7.0" long x 1.5" ID tube, 16.2" assembled barrel.
1/2-28 thread.
Only $850.00 for a complete gun!

Did not get fancy with the necessary slotting of the cup.
Done to reduce weight and to preclude anyone claiming the cup could be used to create a suppressor.

Per buyer request I inlet the stock to clear the cup but would rather avoid that in the future.
Much simpler to just shorten the fore-end a couple of inches, dress, and repaint it.
An 11" barrel needs no modification to the stock.

ETA, gone to Texas.

Posted video I took this morning on YouTube and the sound reproduction is terrible.
Seems my cheap camera is not really compatible.

Uploaded it to my own site as a quick-time movie and the picture is smaller but the sound is better.

What is probably most important is that it feeds and ejects every round.

[Kanook]

The link/video doesn't work for me.

Can't find the Youtube either

[Richard/SIA]

Got to love the 'Net, "HTTP" used to be a necessity, now some browsers are not compatible with it.

Youtube, https://www.youtube.com/watch?v=uN74O9m ... e=youtu.be

[Kanook]

Thanks for the video link.

That is a very interesting and you are very talented to be doing these.

[Joker31D]

Shouldnt just about any 223 based bolt gun work? They are very close in diameter for the 9mm and something like a savage AXIS or model 10 is a breeze to rebarrel, if the RIA rifles dry up, it might be a thought. I'm thinkin I want one of these, but cant figure out whats stopping me, are you going to do one with the Integral so there is one stamp like your prototype? I'm not a fan of the birdcage, maybe if it was made to look like a heatshield instead of a huge finger ripping cage. maybe elongated holes or just perfs like the mossberg heatshields. a 10mm would be the thing if you were hunting a big sounder of hogs, headshot after headshot would clear them out in no time! love the video btw.

[Richard/SIA]

Most .223's use magazines that are too long to feed well.
The TCM was designed from the beginning to use a 9mm compatible magazine.

For slotting a cup almost any pattern is possible, I wanted to remove as much material as I could to reduce weight.

Sweetness!
Give me 2-3 months to save up and I will take two in this configuration (one for me and a gift for my old man)

[jdj]

speaking of decreasing weight, have you thought of using a 1/2" diameter barrel liner for the blank (1:10 twist, see below), inside an aluminum outer barrel, like many 10/22 barrels. Could you do this as an option? Should still be able to thread 1/2-28 and use the aluminum shroud for the threading shoulder. Could have the barrel shroud welded or brazed to the aluminum (or even turn down and bore out a 1.5" billet).

http://www.trackofthewolf.com/list/item.aspx/637/1

[Richard/SIA]

Truthfully had not.
Really trying to keep it simple and cost low.
Just got another order today for an integral "Cup" type.
I will research the aluminum barrel sleeve idea but if I'm doing that why not go to carbon fiber and be even lighter?

[Richard/SIA]

Couple more with the integral "Cup" or sleeve on the end.
Even with the cup they are lighter than original.

Larger cup is to clear a Bowers unit.

A painted for-end as a gunsmith I might faint.
Nice work Richard.

Pretty sure that's how they come from the factory.

[Richard/SIA]

The "grip cap" is also painted from the factory but the butt pad really is solid rubber.
Recoil is on par with a .22 Mag.

No insult intended.I'm a old world gunsmith that carves stocks and is fair with a checkering tool in hand.You don't see to many rifles these days with a ebony for-end or a Schnabel or dare I say a inletted grip cap.While your prices are very reasonable I don't think people would pay another 3-500$ for these services.I would like to see a .45acp version of this rifle.
-CL

[Richard/SIA]

Sadly .45 acp is just too fat to work from the magazine.
.40 sw, 10 mm, and .38 Super are possible with slightly reduced magazine capacity.

I will be assembling a 10 mm demo unit soon.

[Richard/SIA]

Finally got a "Normal" Novem carbine built.
One that won't outrage tradition so much.


Barrel is threaded 1/2-28.
I put an AR 9mm birdcage on it as a thread protector.
