I am going to have my #1 rechambered to 458 Lott. My question is where to pick up a die set. I have found some brass at Huntington's. Thanks, Tom

I just ordered dies for my .470 Capstick from CH/4D (www.ch4d.com). The .458 Lott is in the same group (Group G), and they cost $84.

I was pleased with the knowledge Dave shared with me on necking up .375H&H brass (I ordered some tapered expander plugs so I can neck up in stages).

Hornady wanted $180 for the same dies.

Hey - Where do I find the info for necking up the 375 stuff.. Thanks MD

You can use RCBS .458 WinMag dies for the Lott and Watts. Shorten the sizer to 48 mm. Pushing the case through will result in a ghost shoulder. .416 RemMag brass you can open with the respective die.

------------------

Ditto Norberts post, save the $ and get the RCBS win mag dies. If you neck up 416 brass, a few cases will have lopsided necks, but trust me, they will straighten out upon firing! If I build another 458 lott, I'll use the win mag dies again.

I think I'd get a set of Custom X dies made for the Lott so I didn't have to trim..I did that with my last 404 and it was a boone to my disposition...RCBS.

Ray,

I didn't know that trimming brass had an effect on ones curmudgeoninity. ;-)

I agree that not having to trim the lott brass would certainly be a boon, seeting/crimping trimmed brass, then forgetting to trim and doing with the same setting resulted in a crumpled case or two. What I would highly recomend would be a lee factory crimp die, especially if one feels up to fooling with seating depth, and still crimp. If lee makes a factory crimp for the 458 winnie, all one needs is a .30" collar for the shell holder, I use something similar to use a 358 win crimper on the 35 whelen.

Paul,
I use a undersize sizer button...I usually trim them to .003 or .004 undersize on the lathe and that gives a tight bullet fit..In the lot it actually creates a reverse shoulder that can be detected in good light..the bullets will not set back with a light crimp...

I do dislike the trimming of cases and intend to exchange all my dies for X dies as they become available..

Why? I have no idea, I could not shoot up all the ammo I have loaded in two lifetimes and I'm a bit over the hill already, at least according to some Aussies that lurk around here..(grin)and they ain't wrong, but I still feel like I'm 40...

check out my answer that I put in the wrong place it's call it's called here is your answer or something like that.

Hi TJC,

RCBS makes a 3 die set in 458 Lott - check out their latest catalogue or go to Graf and Sons http://www.grafs.com/ to order on-line.

I get unstamped brass from PMP in RSA, it's basically their 375 H&H brass taken off the production line before it get's necked down to 375 - case length is 72,5 mm and may need some trimming depending on your rifles chamber.

I just loaded up a 100 rounds using the above combo and am very happy with the end result - don't foget to add a decent crimp.

Regards
