460 S&W: Velocity / Barrel Length

[ruggyh]

Impressive. Makes we want to dust of the 460 and 500 and take them out - I have not shot them since covid :-(

Anyone have one(or more) of those awesome Big Horn Armory Model 89/90 lever guns?

Yes, I have a 500 carbine and rifle and carbine versions of 460 Bighorn lever guns- they a very nice rifles.

.....
Was told the muzzle brake on the 7.5" is removable.
.....

If you remove the comp on 7.5 PC model (unscrew it) the barrel shroud of the will come off and the barrel is unsupported.

While it is possible to make the 7.5" uncomped it takes some work and special tools to do it.

Here is a thread on an uncomped 6.5" I did.
The 460 Smith & Wesson didn't make!

For those wondering about what the 460 round can do from a closed chamber, not a revolver! I put together a TC Encore w/20" barrel and before I had a scope mounted we fired it over a chronograph. 200gr Hornady FTX from a 10.5" barrel on a revolver was 2450fps and from the 20" Encore it was 2999fps! Just think, the old standby, the 30-06 with a 200gr bullet goes how fast?

-- and just over 3000 fps from the Ruger#1 that are available.

Thanks all.

I ask because I'm deciding between the 460XVR HI VIZ 7.5" or the 460XVR 8.38".
The possibility of a little more velocity with a somewhat longer barrel is a factor to consider.
Would anyone like to say which they prefer and why?

The effective barrel length of both models is 7.5".
The PC is a little heavier because of the unfluted cylinder.
Accuracy is the same esthetics and cost are the difference.

Her is thread discussing the 7.5" version.
