need some info Ruger New Vaquero bullet length

[silverbuzzard]

I am going back into the 45colt and buying a Birdshead 3 3/4 New Vaquero
Can you guys tell me if I can put 300 grain SWC in that cylinder and if not ,how heavy?
Also would like opinions on how WARM I can load it. Notice I did not say HOT, I know it's a smaller cylinder
Can I get a 285 or 300 grain buller going to 900 fps in that gun and barrel length ?
Would like some loads from you guys also.

I heard max was around 280 - obviously the nose to crimp is the key measurement.
This is interesting and discusses this issue among many other things about the New Vaqueros

"The New Vaquero was tried with
a variety of handloads that included both jacketed and cast bullets, ranging in weight from 225 to
285 grains. Overall accuracy was
good, which is probably due to the
correct throat tolerances, good
chamber alignment and a quality
barrel. Bullets should be chosen
that keep the overall cartridge
length to 1.66 inches or less, or
bullets may protrude out the cylinder, tying up the gun. Generally
this is not a problem but should be
noted, as some commercial cast
bullets feature a nose length exceeding .375 inch and are intended
for Ruger Blackhawks and “old”
Vaqueros."

The New Vaquero is safe with 45 ACP +P pressures, which are 23,000psi. That's a little warmer than the 14,000psi SAAMI spec for the .45 Colt. It's possible to get a 300grainer into the 1100+ f/s range by carefully picking and choosing powder and bullet, not sure that can be done with the short barrel but more likely a 280gr might be the sweet spot for one of those and still stay within it's safe pressure ceiling.

Also, there is a fairly large gap between the standard .45 Colt loads safe for an old Colt, and the too hot for the New Vaquero loads that are labeled "Ruger or T/C Only."

What is needed is load data for a midrange .45 Colt. One of the biggest reasons for this lack of data in those pressures and velocities, is that the .45 Colt case itself is rather large and many powders do not like being loaded down, some of them are quite position sensitive and can lead to wide spreads in velocity and unexpected pressure spikes if not loaded to the minimum amount specified by the powder mfgr. H110 can be very dangerous loaded below the starting amount. In the Ruger Only loads, slow burning shotshell powder seems to provide excellent results. For midrange velocities and pressures below 23,000psi, gonna have to do quite a bit of research to find good load data.

Go to the Hodgdon reloading data website and search under 45 colt loads for the Ruger or +p. They have loads listed for a a jacketed 300 gr. and cast lead 325 gr. under the 23,000 PSI that your revolver should be able to handle. These are starting loads, be sure to stay away from the max loads as your gun is built on a mid size frame and will not handle the max Ruger Only loads.

Regarding the " generous " case capacity of the 45 Long Colt, that characteristic of the 45 Long Colt case along with the fact that I have about 3K, 45 ACP cases led me to decide on the 45 ACP chambering for my own Ruger Birdshead vs. the Long Colt chambering.

While I'm not in the 45 ACP + P arena with my current load below, it seems adequate for my application ( Bad Guys Beware ! ) :
