I'm thinking that the crimp line will act like a checkbook burst perforating line, break off the neck and stick in the chamber eventually.

When I got my 256 win Contender barrel I could not afford form dies so I lube up some once fired 357 cases with Lee sizing lube and slowly ran them into the 256 die doing it in stages with lube in between . I had about a 5% failure rate but I had brass to reload! Have fun with it. Mine liked the noe 70 gr cast. Tim
I, too anneal my cases before forming and rarely have any issues. I have also experienced the fact that Contender barrels in the 256 WM do not do well with heavy boolits. Fun little cartridge, for sure!
The 256 WM is another of those great forgotten cartridges. I had a Contender in that caliber. It was great for jack rabbits with the 60 grain bullets. Mine liked the 87 grainers and was a killer on javelina. I used it to shoot metallic silhouettes and it would knock everything over, if I did my part. Had to hit the rams high. There was gentleman at the last gun show I went to that had a custom B78/1885 in 256 win with dies and brass for sale. I'm regretting now that I didn't grab it.
Following this thread with great interest as I just started with Contenders. I have always been interested in the Marlin 62 in .256 Winchester so after getting the Contender I have been looking at barrels in .256 but the brass situation has had me reluctant to get one but now I think I might just have to get me one!
you can also use 360dw brass just like grumpa did
I just annealed and reformed 70 mixed .357 brass to .256 with NO losses.
Thanks, TxCowboy52!

I have a 14" Contender .256 barrel on order from MGM, expecting it any day now. In preperation, I just made 100 cases out of new Starline .357 brass. It require 103 cases to get 100, and they look real good, not bad. I had anticipated doing a couple neck reduction steps, but first tried just running them in .256 die with Imperial lube. Found that was all I had to do, didn't bother with any steps. I won't know whether I need to turn the necks until I get the barrel, but I'm really thinking not. That, we'll see.
3.5 grs of Red Dot and the NEI 257-85(.258” and tumble lubed plain base) using Fiocchi SPP; group is 7 shots @40 yards.
I think that I have the makings of a good edible small game load here.https://uploads.tapatalk-cdn.com/202...fbb90d0107.jpg

That ought to be the ticket.
So......I bought an old Universal Carbine in .256 mag a lomng time ago. It came with a partial box of ammo, but i have not found any more. I finally bought a set of dies and started reforming .357s....unfortunetly , I found that the shoulders would not push down far enough . I asked my son who has a lathe to remove a few millimeters from the bottom of the sizing die, and that seems to have worked...reloading is something i do in cold weather or very hot weather, so I will be trying some of these ideas soon.... thanks.
I think that I remember those from old Shooters Bibles- isn’t it an M1 Carbine copy?
Does it feed the rimmed cases ok?
