Rossi 92 Ranch Hand SBR project (short barreled rifle)

[Full.lead.taco]

Been wanting to do this for a while. Just got my approval & tax stamp from the ATF so I can start this project.

End goal: Suppressed short barreled rifle to lob some quiet 45's

Steps:
1. Engrave receiver
2. Install rifle stock
3. Thread barrel for suppressor
4. Shorten the magazine tube to be flush with barrel band (cut, redrill, & tap mag tube)
5. Replace default iron sights with suppressor height sights and/or drill & tap barrel to take the NOE barrel mount pic rail and mount a Red Dot sight on top
6. Replace oversized loop lever with normal sized loop lever

That will be about the most fun you can have with your clothes on! Can't wait to see how it turns out. Hickok45 made a utoob video showcasing a loaned, converted Mare's Leg, but I think it was in .38/357. I much prefer your choice of caliber.

Do you already have a .45-caliber can?

 

[Full.lead.taco]

Yeah, I kind of went "all in" before the Obama July changes last year and bought all the suppressors I thought I would need or want. I have a lot of family members on my trust, and it would be nearly impossible to get them all to do fingerprints and photos for any purchases after July. So I sold a few things and bought lots of suppressors and filed my form 1's to do my SBR's all before the July deadline. So yes, I have the 45 cal suppressor(s) I can use for this project. I had thought about doing one in .357, but I figured I enjoy shooting 45 colt quite a bit more--so I went with the 45 colt option.

4.5grs of clay's and a 250 rnfp.

 

[RBHarter]

19 gr of H322 and a 350 if your twist will support the bullet . Runs about 1100 at 4100' MSL and just at the cusp cleaning up out of 16" bbl .

I second that, especially if he chooses to powder coat the bullets so the can doesn't get leaded-up. Titegroup might be a little more consistent but does that funny thing with Polyester powder coating.

 

[Full.lead.taco]

Yeah, I want to keep all speeds down to about 1000 fps or a little less, and the bullets will need to be powder coated for the suppressor's sake.

I'll be watching this. Please keep us posted. With pictures, if I really need to say that.

Uhh, please share pix....lots of pix!

Hokay! so the little firearm is now in the hands of a local gun smith to get the mag tube shortened and barrel threaded. I also opted to get the barrel drilled and tapped to use the NOE Rossi 92 scope mount/rail. That way I can use it in low light conditions (red dot) if needed to take care of any pesty critters on the farm or out in the country. Firearm receiver has been engraved. I need to figure out where I can get a standard sized lever loop instead of the big loop. I really don't like the big loops for practical reasons. When I get it back, I will share some pictures or post a video.

What do you have to engrave on the receiver? Some ATF number or what?
Seems like just putting the original SN on the papers would suffice.....but then I am
using logic in a logic free zone again.

I have to engrave the name of the trust, the city, and the state per atf rules.

I have the firearm back from the gunsmith. Threads are a little tight with the suppressors. Any good tips besides throwing some oil on the threads and threading something on and off over and over? Also, any favorite "quiet" cast loads in the 45 colt you guys have? I figure I will try the red dot load, but also up for any loads you have had good luck with.

 

[RBHarter]

Any 250-265 with less than 7.0 Unique ? Donno what it Chronos but 8.0-.5 is over 1100 in my 16" here at 4000' .

5.5 in a Schofield case with a 454424 isn't wasting any time either .

Qualifier I'm shooting a 1968 lot of Unique it doesn't even look like the new stuff .

Titegroup or Bullseye due to relative powder position insensitivity, low gas volume, and very low muzzle pressure. Titegroup outshines BE by a wide margin in both aspects and both of them are miles better than RD.

Take it back and ask to have the threads chased with a die, or do it yourself if you have one. They probably single-pointed the threads to the fat side of class 1B spec or whatever their SOP is to be on the safe side, and dies often make OD threads a little on the loose side so they may not use a die to final-chase them. I find having taps and dies on-hand for all my muzzle thread patterns to be VERY handy at times, especially with all the variances out there and on several occasions buying used brakes that are full of Loctite or Rocksett residue.

Permatex valve grinding compound. Tiny dab'll do it. It breaks down to a fine grit very quickly & cleans up with water. Use it to chase threads on rotary extractor hubs when they get gunked up. Works like a champ. Its not great for valve grinding but, works great for chasing threads.

7.5-9gr of titegroup under any 300gr should find you some love.

I ended up picking up a couple threading dies and chased the threads. Much better now. Almost completely done with the build. Took it out on saturday to test some stuff out. All I had were some plinker 200 gr unique loads. I need to load up some of the 250/255 gr clays loads and see how they sound suppressed. Once I get stuff all good, I will post some pictures or video.

 

[Ian]

Thanks for the follow up, always nice to see how things progress. Chasing the muzzle threads down instead of lapping to fit the suppressor keeps the fit from being too loose on your other muzzles with the same can, if you swap it around.

Finally got around to putting a video together. Here is the gun:

Was going to look at maybe getting a leather cheek riser or something. Any of you have ideas to raise the cheek weld a bit?

 

[Ian]

Keeping with the "tacktical" side of things: https://www.voodootactical.net/voodoo-tactical-adjustable-cheek-rest-with-ammo-carrier.html

Otherwise I good set of Skinner peeps with the high front blade.

Regarding the levers, the enlarged ones which are just bowed out at the bottom are handy if you have gloves on, even just work gloves. HOWEVER, I think the enormous, exaggerated, barrel-hoop Hollywood levers are pretty stupid and impractical on a rifle. Maybe ok for some people on the Mare's Leg but my problem is the stiff Rossi action makes the pistol roll in my support hand while working the lever, making my knuckles slip off and about half my arm pokes through the loop.
