TX22 FRTs

[strobro32]

3- 10 rd burst ROF average on 2 oz weight and 1.3 oz fixed weights

2 oz weight:
CCI Subsonic Clean 40gr. RN and CCI SV 40gr. RN- unreliable
CCI MM 40gr. 1496 RPM

1.3 oz weight:
CCI Subsonic 40gr. RN and CCI SV 40gr. RN- unreliable
CCI MM 40gr. RN -1600

Great to hear.
So did you settle on a standard weight yet?
In otherwords .....


I found springs for the 9 rnd extension print.
Going to look around a bit since all the sellers are in chyna and chyna is asshoe. Not to mention tarriffs.
With the 50% tarriffs a 50 dollar order comes out to over 85.00 after shipping and at least a month of waiting.
See if Mcmaster, grainger, or another supplier in the US has them.
I really need to set one of the lathes up so I'm not stuck or forced to pay for stuff I can make.

Anywho glad the box is working out for you.
If you need more of them or anyone else wants one just let me know.
I'm happy with the 450.5 grns added and the reliability and ROF it has.

 

[strobro32]

I think that is a good weight for reliability with supers and subs. I think it will reduce wear on the slides. I liked the fact that 2 oz made HV ammo run at 1500 RPM.

I also wonder if where the weight is placed on the slide matters.

Many of the people who were testing with suppressors were using light suppressors (aluminum and 3D printed) I'm sure that is why my heavy suppressor can not reproduce the same numbers or reliability. The suppressor can get hot fast at these ROF.

I watched a great but scary video of how it's almost impossible to not source parts in China. The scary part is we are loosing the intellectual knowledge to make the things that make things. The old cliches about China MFG are not true anymore.

Sadly Strobro you are right.
My other hobby is made exclusivly in Japan, S. Korea & Chyna.
RC heavy Equipment and Cars.
Not a single US company accept sales.
Why I am personally familar with the tarraffs just 50% out of S. Korea
For a 1500.00 RC it breaks down to 700 in tarriffs and another 200 in shipping.
I beat the Chyna tarriffs last April because I knew they were coming and spent 6k on a hydralic loader & excavator now imagine that same same 6k with 50-100% tarriffs.
I say Chyna is asshoe because of their cultural difference.
Takes them around 3 months to fix a 1.5 hr software glitch via a signal video conference.
Not because they they don't know how or they have your money but because it doesn't matter to them.
The consumer will wait their turn until they have the free time due to their commie cultural beliefs.
In otherwords customers do not come 1st after sales.

Anyhow back on topic.
I'm going to look around today and see what is in US stock that isn't 24.00 per spring like the gun sites are selling I'm sure it is the same 9.00 spring from the same chyna seller. It's a nothing special spring after all.

My root box broke this morning. I was testing 1.2oz weight and then the box was gone. It snapped at the back plate. I'm not sure where it went. Maybe it vaporized.

I think around 1-1.2 oz is good for use of a suppressor. If someone makes a steel striker assembly we could be there.

 

[strobro32]

Root what amno were you using in the Spectre video?

 

[root]

CCI subs 1050 fps
Pretty much all I order from CCI
last weeks order came to .14 cpr for 1000, well worth it if you read my last post in the SS review thread.

I buy the quites locally since there are a few places that carry them on the shelf but almost never any CCI subs.

ETA: by your description I have the same TX22 as you Strobro.
PSA sent the wrong gun and in this case I could care less it works.

Just now seeing CERN ate ypur box in the post above.
Not sure how I missed that.
Get ya another box in the mail.
I'll send a few.
Surprised it came apart the way it was orientated for printing.
Mine is holding on so far.

 

[strobro32]

I appreciate that but I think we know what weight works. I just need to figure out how to add the weight safely with a non optic cut slide.

 

[skoda]

Weld it on.

 

[arch stanton]

Had the first dead blow with the specter can today using Winchester M22 sporadic ignition at best. Added .52 oz of lead tape and cured the issue I will probably not use the specter any longer regardless it was interesting. I will stick with my suppressor which is a branded Gemtech Alpine also a shorty AWC titanium and Odessa from SRT. I see that GSL still makes the Alpine.

I got my shipment of TX22 FRTs in Friday but they are %10 too small. I'm not sure how they made it to me without someone taking measurements. The company produced new ones this weekend and are shipping them out to me today. May take a week to get them.

In the mean time I did find an outfit who sells them cheaper than FFT. https://www.brrrtbutton.com/

I still will sell at 25 if I can get them to work.

 

[strobro32]

In this video, the guy has done a lot of work to figure suppressed TX22 FRT out.

https://www.reddit.com/r/22lr/comments/1ngxdyn

His ROF is 1401 RPM. That's the slowest ROF I've observed yet.

Key take aways:

"Holosun 509t will run hotter ammo suppressed perfectly at 3.8oz total. Target weight for me is ~2oz though to support more ammo.

I am going to keep playing with the optic choice, but to save other folks some time/money, the Viridian RFX11 that comes with some TORO packages is too light. It’s actually a couple of grams lighter than the optic plate that it replaces. Great for standard semi-auto use and a decent optic for the price, also held up fine for FRT work unsuppressed but too light for suppressed.

The OSight (OLight) S optic is a bit heavier but not heavy enough. I will say that while the box has some cheesy type that is dead giveaway Chinese import, it’s actually not a bad dot. Still too light for suppressed work but could be fine, maybe, if you use CCI Quiet or some other underpowered ammo, maybe with a light spring? I haven’t tested with a Galloway light spring, just guessing so buy at your own risk.

What I show working in this video is full blown artistic behavior: RMSc to RMR plate (Cross Armory), 509t RMR adapter plate, and Holosun 509t. That total package adds about 3.8oz and runs hotter ammo like Remington Thunderbolt (this video) perfectly with either the DA Mask HD or CAT SR. It was just a bit too much weight for CCI SV though, and that is the ammo I run the most in 22LR pistols.

I am going to try a Holosun 507c next to see if it’s 1.5oz + adapter plate get me to ~2oz like the ACRO P2 that I have seen Pew Culture recommending for suppressed FRT hosts."

He seems to think 2 oz is the target weight. I found that 2.1 oz suppressed was too heavy to support anything but CCI MM.

I don't want to ad an optic to my 4.6" TX22 but I have another test box in the mail thanks to root. The video seems to think that a Holosun 509T at 1.71 oz would be the best way to run SV ans HV ammo suppressed with an optics cut slide.

As I'm learning, What might be right for you, may not be right for some. Different strokes and all.

 

[strobro32]

I do not understand some of the research here. I tried the supported and unsupported bipod attached. Mine didn't work with subs or HV ammo suppressed.

Why does some peoples TX22 work with a suppressor and most do not?

 

[slimshady]

Standard manufacturing tolerances between guns.
Variations of the suppressors, weight and back pressure.
There are several different slides for the tx22, some have optics cuts, lightning slots, some are solid. Different weights?
Some or all of the above?

 

[root]

I would agree with slimshady.
If you look at the palmetto page for tx22 pistols they list 4 pages.
I get it a lot are just different colors but it seems there are like 6 or more models in current production that are for sale.
Ranging from the 200 guns we bought to the 500 comp guns with prices in between.
I'm not seeing a universal fix all for these yet.
Kinda looks like each gun will need dialed in on it's own

Was shooting mine yesterday with my son and it seems dialed in for reliability.
No stopages or failures yet accept one dud. And that could possibly be age since I'm shooting pre covid ammo.
We set aside Tuesday evning to see how many rounds it will go before failing since it hasn't been cleaned yet.

 

[strobro32]

today's experiments:

Stick on wheel weights on top of the slide.

Host- 4.6" barrel Taurus TX22 Gen 2 non-optic cut slide and FRT.

SOWW added to top of slide with use with a 5.8oz SilencerCo Sparrow.

1 oz
CCI Subs 40gr -1411 RPM
CCI MM 40 gr - not functioning reliably

1.5 oz
CCI Subs 40gr -1293 RPM
CCI MM 40 gr - 1322 RPM

1.75 oz
CCI Subs 40gr -1104 RPM
CCI MM 40 gr - 1295 RPM

2 0z
CCI Subs 40gr - not functioning reliably
CCI MM 40 gr - 1253 RPM

This information seems to concur with illesdomer2005 guess that the 1.75 oz weight is the best for flexibility between subs and HV ammo.

It also appears that where and how the weight is added on the slide changes the numbers. Using a 3D printed box connected to the back plate, the ROF number were slightly lower. I will need to retest using 3-10 rd averages to verify.

 

[arch stanton]

If it makes any difference this is the package I am using from Palmetto.

https://palmettostatearmory.com/taurus-tx22-gen2-22lr-4-1-pistol-w-3-16rd-2-22rd-magazines-black.html

I will weigh the slide with the barrel and without to see what the starting weight is. Maybe they are not all alike

 

[strobro32]

root and I bought the one you did.
