Don't rip me a new one if I am wrong but wouldn't a 458 on either a SAUM or a Win Short mag have more capacity than either the 450 marlin or the 458x2. Are not both cases bigger in diameter than the standard belted magnum?

I'm building a 458 RSAUM. I have a 700 BDL, a 458 caliber remington barrel off of a different project. I'm just wondering about who to do the gunsmith work? It's not going to require too much work. I'm just wondering who everyone has dealt with that did a good job? Thanks

As I recall, there was a gunsmith that posted pictures of a 458 short mag he'd built on either the big bore or gunsmith forum. I can't vouch for his work, as I've never used him.

I have had John Ricks of Shooting Star Rifles barrel several actions for me, and he did a great job on all of them. He is both accuracy oriented, and a big bore fan. I don't know if he is currently taking work, as he had quite a back log.

That is John Noveske and his web site is: http://www.jnrifleworks.com

He uses the WSM case but might be persauded to use the SAUM case.

i'll ask..


WHY!!!!

How would this be superior to a 450 marlin?

I'm gonna use it in a bolt gun, not a lever. I can use pointed spitzer type bullets for elk and deer and hogs. Can also use cast bullets for cheaper practice. And hopefully will make it into a 7.5 pound rifle. And it will be able to approach the ballistics of the 458 win mag. It is within a few grains of the same capacity in a short action. That's why. Plus I just prefer the rsaum over the wsm case.

Okie,
the 450 marlin is exactly the same thing, except the belt, as the 458x2"... and excels in a bolt gun... and you won't be paying
150 for a custom reamer
160 for custom dies
100 for custom headspace gages

and it's already being done in mod7/70compacts

the suam is a SMALL case...

I'd like to hear about the loads that will give you 2400fps with a 400gr bullet in the 458x2" or it's ballistic twin the 450 Marlin.....that's more than 5100 ftlbs of ME.

Good question, actually the 458 win mag is hard pressed to push 400 gr 2400 fps.

I would think a 458-2" is more like a 350 gr @ 2200-2300 fps round, and that's nothing to sneeze at!

Noveske is getting about 2600fps with the 300gr Barnes in his 458 Noveske (WSM Case) but that's in a 16.5" barrel. You could probably figure an extra 100+ fps by going with a 22" barrel and let's face it, 2700+ fps with a 300gr Barnes bullet is a pretty impressive 4850 ftlbs of ME.

Here's a picture showing...from the left... case from 9.53 Lazzeroni Hellcat, a 450 Marlin and John Noveske's 458 based on the necked-up WSM.

Okie,
we have a local gun smith who visits the forum, by the Name of John Noveske. www.jnrifleworks.com is his website.

He has done that on a Winchester short mag case in 458, and Hornady actually offers the die titled 458 Noveske.

I have seen some of his rifles in this, and he has done several barrels for me and his work is highly recommended.

each one have been tack drivers.

Cheers and good shooting
