Load details please?

34gr of Alliant 2400
Lehigh 100gr CQB slugs
COL 2.067
Velocity out of my 16” 458 is around 2850fps but I haven’t used the chronograph on my 10.5” with this load yet.

Better pic of the muzzle device as well?

Those are frames from a video, why not just post the video?

I didn’t have an editor at the time.


Id be worried about the safety of my eyebrows with that thing erupting in a little lane stall like that.

Not as bad as you would think, more bright than anything else.



WOW! I can't imagine any indoor range allowing people to shoot a 458!

Ballistics are on par with a 45/70 so as long as your range can handle that you’d be ok. It was empty, the closest shooter was several bays away and we know each other so he was ok with it.

WHat's the noise like? I imagine it is going to replace the M91/44 as the "very big banf and huge flash" weapon of choice. BTW, what are you doing with .458 in a 10.5 inch barrel?

It is extremely loud with those slugs, the 405, 300 and 325gr slugs I normally shoot have a good bit of pop but the aluminum ones have an amazing boom to them. Why not a 10.5” 458?, going from a 16" to a 10.5" I only lose about 80fps. That is with 300, 325 and 405gr slugs though, like I said before, I haven't chronographed these yet.


Aluminum slugs ?????

Yes, aluminum.

I'd imagine its built for CQB.

That is what they are advertized as, Defense / CQB. I couldn’t imagine shooting that in a dark house without hearing protection though. I did some testing on phonebooks and the slug managed to make it into the second book, the only deformation was the aluminum surrounding the hollow cavity snapped off into 3 or 4 separate pieces like petals but the rest of the slug stayed together. Unfortunately I can’t find that slug or I would post pics.

Would the bore be subject to "aluminuming" with Al bullets?

Not that I know of, they are coated with a film from the factory I assume to keep that from happening.

Here is the vid, just had to shorten it a bit.
