32-40 B&M Remington Hepburn. Help please

I bought a Hepburn in 32-40 B&M I'm hoping to pick up tomorrow. I have read this is the same as 32-40 WCF. I need to order dies and brass. Thinking of ordering RCBS Cowboy dies.

What length 38-55 starline brass do I need to start with?

You could use either length of .38-55 cases that show up. Or, you could use plain ol' .30-30 and use them. The latter usually ends up a small amount shorter than the 'real' .32-40 cases, but I've shot them for decades without any trouble.
Just remember to check the length after forming and go from there. Good luck.
I have a set of Lee Dies that I use to form cases because they are inexpensive (if they still make them). That way, if I ever wreck them forming, I won't be out much. So far they have lasted three decades or so- I guess I got my money out of them. I also have a set of RCBS Cowboy dies that are nice but don't get used much.

You should actually use the proper length to help prevent from shooting out that portion before the actual throat. It's really best to do a chamber cast and to verify what that might be for yourself. It is just one of those questions that no one can honestly answer on your behalf.

Ballards may be weaker,

Yes the .32-40 that some people attribute to Winchester as .32-40WCF is of course the same cartridge designed by Marlin and thus the .32-40 Ballard & Marlin designation that Remington used.
There is no .32-40WCF, only cases marked by Winchester with their designation as such. It was always a Marlin cartridge.

The 2.08 brass will stretch to around 2.110/15. Then will shrink about .005 when fired. 2.120 stretched to 2.165 .  Both with Star-line new brass and RCBS Cowboy dies and formed in 3 steps. I used the shorter because of price. If i do it again ill use the long and trim to fit the chamber.

Those cases made up from .30-30 are only about five to seven thousandths (.005 thru .007) short. Lots of folks shooting hight intensity cases shorter than max and no trouble ever from it. John is way overstating the issue, my .32-40 has been existing on a diet of those things for decades. Even if you decide to have a .30-40 magnum the burnt out area ahead of the throat is eons down the road. Maybe JL needs to blame his powder and primer choices first.
If you get the old .32 special cases they form up as well and are easier because the neck is already about right and only the shoulder and below need to be resized. My favorite beside my stock of 'real' .32-40s.

JLouis has over 144,000 bullets down the barrel so he does know what he speaks of first hand when it comes to throat erosion. If an individual is not shooting competitively or simply does not care about taking proper care of his or her firearm that will eventually be handed down to the next care taker it is really just a mute point. But also not the way I was raised in regards to being blessed as a care taker to take care of everything I have been very fortunate to care for outside of just firearms.

It could also be chambered in 32-40 Remington which Remington chambered the #1 and #3 Hepburn in. This would have a .309 bullet dia , .330 neck, 453 base and a .535 rim. Cases formed from 30-40 Krag or 303 British.
It looks the same as the 32-40 Balard/ Winchester.

Not if it's marked ".32-40 B&M". The Remington .32-40 wasn't marked that way.
