Twist rate of Rossi '92??

[coyotejoe]

Does anyone know the twist rate of the Rossi '92 in .44 mag and .45 Colt?  Over the past 40 years I've tried out .44 mag rifles, three Marlins, a Winchester '94 and a Ruger auto and none of them were much better than paper plate accurate. Since I have had accurate Marlins and Winchesters in .357 mag and 30/30 I assumed the problem with the .44s was due to the slow twist, all of them were 1-38". So now I'm looking at Rossi '92s, would like a .357 mag but can't find one. There seem to be quite a few .44 mags and .45 Colts but I don't want another paper plate gun. I don't expect MOA but 2-3 moa would be acceptable. My experience with all of those .44s was more like 5-6 moa. I know the new Rugers used a faster twist, 20" I think, and they are said to be good shooters, so I'd like to know the twist of the Rossi '92s.

Dunno on the 45 but am pretty sure it is 1 in 20" for the 44 magnum. My 45s were very accurate with all bullet weights I tried in them up to 325 grains. My 44 magnum does fine with 300 XTPs tho I've not yet shot any cast bullets above about 250 grains in it.

I did try to shoot some Bruin brand factory ammo I had left over from a long ago review and it was too long to fit and feed. I think they were a 310 or 320 grain LBT LFN style bullet and the COL was just too long. I suspect it would have done OK had I fed it directly into the chamber rather than trying to feed them thru the mag tube.

Marlin just hasn't wised up that 1 in 38" doesn't cut it with longer bullets tho our old M336 44 Magnum shoots 300 grain jacketed bullets just as well as the 240s. I don't know what twist they used the couple years or so they made it in the 336.

Based on what I was told when I called and asked them, and per several things I have read online, the Rossi '92 is 1:30" twist regardless of caliber.  I have them in .357 and .45 Colt and both shoot very well with everything cast I have tried in them with 2-4" groups being normal for me at 100yds with the issue iron sights.  I size everything between 90-165grs at .358" for the .357, and everything between 200-325grs to .454" for the .45, and get no leading.

All the Rossi's have a 1/30 twist except for the 30-30 which has a 1/12 twist.

Thanks guys, I just got emailed the same info from Steve Young the "Rossi '92 specialist", he is renound for his tune jobs on Rossi '92s. Looks like I need a .44 mag, I have a ton of bullets and brass left after selling my Ruger flat top.
Here's a couple of links Steve sent me that I will pass on to all of you.
