Does anyone happen to know where I can get the dies for this round?
My grandfather made custom rifles, the rifle I have is chambered in 6.5 Souper, a round I believe was designed by him as well.
Sorry to resurrect this post from the dead, I realize it is old, but I can't find much information on the web.

Redding makes 6.5-308 dies, they're available at Brownells. Lambert started the 25 Soupers in the 50's, so that moniker became popular for any necked down 308win case among certain wildcatters at the time. Most folks just call them XX-08 these days, attributed to Remington's 7-08. Kinda in line with how guys "ackley improve" all kinds of cartridges that Ackley never developed himself (although he did AI pretty much everything under the sun). Or maybe your grandpa is Lambert...?
Now, if your grandpa wildcatted a reamer on his own and dubbed it a 6.5 Souper, then it's quite possible that your chamber won't match up perfectly to the Redding dies. Whether your grandpa developed it or not, if whoever drew up the reamer had a logical mind, they kept things simple, kept the 20deg shoulder of the 308win like the other xx-08 cartridges, so a 308win FL could be used with a 6.5 seater, or a bushing for neck sizing. If tried to do something like AI it, straightening the taper and blowing out the shoulder at all, then your life might get very complicated.
Frankly, your next step should be to take a chamber casting, then compare that against 308win and 7-08 prints, and send the dims to Redding to compare against their 6.5-308 dies.

If you want a little history on the 7.62x51 NATO P.F. Lambert was in charge of the research department at the pentagon that developed that round then he suggested to Winchester (which is funny because previously he had worked for Remmington) that they standardize the .308 and .243 - that I can help with but his "wildcats"...

So since you're dealing with real deal Lambert Soupers, it's a pretty safe bet that he used the same 20deg shoulder and headspace dimension. I'd venture that it's also a pretty safe bet that Redding used the same also, but they weren't obligated to use the lesser known 6.5 Souper moniker, or maybe not legally able to use it, so they use 6.5-308.

Pull the bullet and empty the case and send it in to Redding. Pop the primer too. If you KNOW those are the correct cartridges you have (the 2 you said you had left) then that would be the absolute best course other than casting your chamber. But more than likely Mercy is correct in his assumption. (Kids pretty smart for a Kansas boy

I am still trying to figure out which are the correct Dies myself. -
i have the measurements of an unfired case here - 1 is 30-06 Frankfort arsenal from 1960 match ammo "FA 60 MATCH" and the other is "Super Speed 8mm MAUSER"
A) .470"
B) .468
C) ?
D) .431
E) .300-.295
F) 1.73-1.74
G) 2.91
Length to point G - 1.875-1.890
H) 2.17
I am currently searching our my box of fired cases (they would be formed to the chamber - am I right?)
and my gunsmith some time ago said he would cast the chamber for me, need to get it over there.
I would be interested as long as they are the correct dies - apparently there are several small variations to 6.5-.308
Unfortunately I do not have much experience reloading and would rather make the purchase only once.
