Taylors doesn't "make" anything, their current 92s are Chiappas.
The Winchester brand name is still owned by Olin who licenses it to Browning who's also owned by FN in Belgium. That was done to allow Browning to import & market "Winchester" branded guns, foreign or domestic.
USRAC began as a standalone company formed in the early 80s to produce Winchester-branded guns under license from Olin when Olin wanted to dump the firearm branch. Olin kept the Winchster name, just sold off the firearm production side.
USRAC was subsequently sold more than once & ended up as only the manufacturing facility in New Haven & owned by FN. By the time that factory closed, USRAC was no longer an independent company producing & marketing guns. It was just the factory, owned by FN, making guns for Browning to market.
New Haven guns made at the USRAC plant were marketed & serviced by Browning's operation for the last years it was running.
USRAC was only sourcing MIROKU guns from the same place as Browning.
The Rossi .454s were not dropped because they couldn't handle the round. As Craig says, low sales.
Talked to Steve Young this week, he's planning to convert a .45 Colt Rossi he has to .454. That should tell you something about the viability of the caliber in that gun.
Rossis typically come oversprung & relatively rough inside. The current Rossis also come with an annoying wingnut safety on top of the bolt.
That can be removed, Steve Young has a plug for it.
