XP 100 in 458 win mag?

[Snubshooter]

I don't think the action is long enough in the xp for the 458. As to recoil , I have a Gary Reeder Custom Encore in .300Wby 14in brl. I thought the recoil would be horrendous, I got sandbags and a jackhammer glove in preparation for the first shot.... IT WAS A PUSSYCAT. Gary's compensator was magic, It feels like a 6" .44, a JOY to shoot. What I'm saying is with the right tech recoil can be managed. Of course My baby spits about 5 feet of flame and the boattail scoots out there at around 2500 fps.

The XP-100 can handle the the 458 Win Mag case.
Case length is 2.5" and one load data says the OLA is 3.340

I have a center-grip XP-100 chambered in the 338 Lapua case, but improved.
The standard 338 Lapua case measures 2.724, and the OAL on my loaded rounds is over 3.75".

97.0 grains of Retumbo with the 300 grainers (Berger and or Sierra Match King).
I can unload the fired cartridge without removing the bolt.
But I cannot unload a loaded round without taking the bolt out.

A good partition style brake is going to be more effective, as it will have more surface area to work with than the garden variety brakes that have patterned or random holes.
Also, the solid bottomed brakes are much kinder to the shooter, the gun, and the optics, since they do not blow gas down into the dirt.

I also have a XP in 7mm Dakota

Both of these XP's have high magnification rifle scopes on them as well.

When shooting prone off of a Harris bi-pod, I shoot both of these guns one-handed--Good brakes make everything different.
