I just got a .460 XVR magnum 8 3/4" with a 2-6x32 Simmons scope. Awesome gun to shoot but it will not shoot true with 454 through it. I have seen others mention it but no one has said exactly why this is??? I have shot multiple brands also and they all shoot like crap... Is the 454 smaller and doesn't fit .460 barrel rifling??? Shell extraction isn't an issue at all. I bought the pistol for versatility but I can only shoot the .460 magnum round with any consistency.
Can anyone shed light on the subject or is there anyone loading a hot round for this gun??? Please help!
i have the same gun and got hornady ammo in 45,454,460 and they all seemed to group fine.
had to adjust aim point for each cal tho.
droped a doe at 80 yd. with 460 last sat with a head shot.---very nice.
i use open sights so maybe the scope is your problem, you might try putting the sights on and trying at 25 yd to see grouping and go from there.
Consider that the chamber on the .460 is the same as the .45 Colt and .454 only longer. The different length of "jump" before contacting rifling may be one of the issues. Just as .38 special ammo tends to shoot better in a .38 special gun than in a .357 Magnum gun, the shorter rounds may not be as accurate in your .460.
Different velocities and bullet weights will definately shoot to different points of aim. Heavier and or slower tend to hit higher than lighter and faster bullets.
In life, strive to take the high road....It offers a better field of fire.

Thanks a lot for your input guys - I have the gun shooting well at 80 yds with the .460 round. I understand that different velocity rounds will shoot differently but to me there should only be variances vertically not horizontal. None the less, I will now buy nothing but Hornady. Ghost - Nice head shot by the way - Was there any head left or just a stubby kneck where a head used to be...???
The .38 Special and .357 Magnum have a difference in case length of .135" and that is enough to affect the accuracy of the Special round in a Magnum chamber in some revolvers. You are looking at a difference of .400+" in case length with the S&W vs. the Casull and close to .500" with a .45 Colt case. Unlike the Special in a Magnum chamber, that distance is enough that the bullet could be coming completely free of the case before enough is inside the throat to prevent yawing. A .452" bullet in a .480" chamber has more room to "wobble" than a .357" bullet in a .379" chamber as well and a larger area to allow gas leakage around the bullet.
I have the same problem with shooting .357 Magnums in my .357 Maximum SuperMag and .38 Specials are even worse. Others with the same revolver have no such problems using the shorter cartridges.
I don't have any troubles with accuracy in my .460 using .454's. I've used 45LC's before, but they were so dirty, I don't use them anymore. I could tell an accuracy difference when using the .45LC's, but not when using .454's.
