how to make 11.15x58 brass?

[trails4u]

Usable cases can be made from .348 Winchester brass--they will be a little short, but they should work. I found it easiest to anneal the case and then fireform it. Brass tended to split if it wasn't annealed first, and I did not have very good luck expanding the necks with expander dies, although that is also a possibility.

I'll comment on this again.... It simply works. Fireform 348 Win brass and enjoy!

what DIA, cast lead heads did you use for the process? how far did you neck size down the brass to start, what load of what powder & how many grains did you use, any filler?

Lyman 446110 mould as cast (about .447/448) for my standard 67/77 infantry rifle and the same mould sized to .440/441 for my 67/77 jaegar rifle with tighter bore. I also use the Lyman 439186 mould as cast for the jaeger rifle. They’re both in the 340-370 grain ball parks.

Using the 50-110 brass neck thickness limits me to the .447/448 on infantry rifle to chamber size without neck turn/ream but I’m lazy right now. I’m willing to bet the stretched open 348 brass would be better for my needs.

I use a lighter 4227 smokeless load because it’s what I have on hand. I have not chrono’d my loads or taken them to outdoor range.

I also partially neck size only with a carbide lee 45 colt die.

My conversion book says the 11.15 x 58 Werndl can be made from 450 NE brass. You would need to turn the rim diameter down and back chamfer then build it up to .090 thick. I assume that the added rim thickness has to be at the front. The a simple anneal, size and trim.

Hope this helps.

Thats what mine says. I was thinking of 11.15x36R Werndl which can be made from 7.64x54R. simple cut down, anneal and taper expand then trim to length and F/L size
