Rossi/Braztec/Taurus M92

[Gary]

I have a M92 that I've loaded a thousand or two of the Keith style 358477 cast in 150(~) gr. that don't group all that well with this rifle. So I have a couple of questions: should I be casting a lighter bullet, say in the 125 ~ 140gr category; and two, do all Rossi/Braztec/Taurus M92's have a 1 to 30 twist?
I've been looking a various molds and like the looks of the 358480; 358269; 358339. Anyone use one of these? I guess that's three questions.

Gary,
My 92 is a sporting rifle with a straight stock, 24 1/4" barrel, and a crescent butt plate. It was imported by EMF and their model designation is "Hartford".

I have done back-to-back tests with Lee's 158-grain RNFN and SWC, and the RNFN very noticeably outshot the SWC. Also, the RNFN feeds much easier.

I conducted the same test with my .38 Special Uberti 1866, and the results were no different.

I've never checked the twist, nor remember reading what it is.
Both rifles have only seen the above moulds.

Hope this helps.
Michael

Thanks Michael; I really like the look of the Lee 158 RNFP, and if I can find it in stock somewhere I'll get the DC version. Aught to work well in my SP101 as well.

if t's a Taurus I'd give the lighter bullet a try for sure.
the newer rifles seem to have had their barrels stretched some giving them a weird spin rate.

I stopped buying Rossi's when Taurus took them over.
too bad too I was just getting to the point of not being able to put any more in the 15 gun, gun cabinet, and I had to put a Browning in there instead to fill it up.

 

[Gary]

I'd like to try some of the Lee 158 RNFP before buying the mold. Anybody have some they'd sell?

 

[Winelover]

I use mostly 158 grain bullets, in my Rossi carbine, either SWC or RNFP's. Occasionally, NOE's 180 RNFP's. No issues with stabilizing the heavy bullets.

The 180's like maximum doses of H-110, while 2400 is my go to powder for the 158's.

Just for the hell of it, I tried SR 4759 with Accurate's 158 grain RNFP.

I didnt realize that they did that to the barre twist in a 357.

My 45 is also funky. But luckily for me my 300G RD mold shoots just fine!

Ok is that a Browning 92? In 357?

Gary - sent you a conversation.

The one on the right looks like a Marlin 1894, is that a Rossi? I didn’t know they made Marlin clones as well.

Gary,
I see Cherokee has started a conversation, but shoot me your address in a PM.

My Miroku-made Winchester 92 in 44 Magnum has a 1-24" twist, as best I can derive. It runs an Accurate 250 grain RNFP/GC very well from 1200 to 1800 FPS. Same story with 240 J-words. I am guessing the Henry BB 357 has something between 1-16" and 1-20"; it stabilizes the 180 grain FP/GC very well to 1800 FPS, and the 195 grain #358430 to 1350-1400 FPS.

I don't know why the marlin 44 caliber rifles stuck with the prehistoric 1-38" twist for as long as they did. It might be just the thing for 200 grain flatnoses in the 44/40 WCF, but I always thought it was surprising when it did so well with 240 grain JSPs in the 44 Magnum. Mind you--I love my Marlins--but these Henry leverguns are eating their lunch.

Hahah the one on the right IS A MARLIN!! That a rare one too 16" 45 Colt ON PORTED. Called the LIMITED.

ROSSI 24" on left.

 

[Rockydoc]

The Miroku/Winchester M1892 38/357 has a 18.25" Rate of Twist.

 

[CWLONGSHOT]

Typical to a carbine/rifle in 357 mag.

1:30 seems foolish.

Factory limited, or "only limited by your budget and gunsmith's skills"? I wasn't aware that anyone at Marlin ever knew there was such thing as .44-caliber blanks with a rate of twist faster than 1 turn in 38".

 

[fiver]

no, the Browning is another 44.
I already had a Rossi in 357, well,, I had one in 44 as well as a model 94 trapper too, but that's beside the point.

 

[CWLONGSHOT]

Marlin had quite a go with that 1:38 twist in 44/45s. But they also twisted them 1:20 just like they used Ballard & Micro groove.

Suprizingly neither has really caused me issue. I have shot twenty pounds 300g at a time thru a couple 45s twisted 1:38 with good accuracy.

The drop through transonic is what killed the 45 Colts . Keep the loads subsonic and everything is fine . They must have been tooled around CASS and the like . The 16" twist in the Ruger doesn't have that issue . I did recently shoot some 350s just under 900 fps and they hit round and with reasonable groups at 50 yd . I don't know why they should have been just barely under minimum twist required by the mountain programs .
