has a new home now - .32 Ideal - Made in 1905.  It'd been stored in a gun safe for the last 30 years. Excellent bore and overall condition. Beach front sight; factory folding rear sight and Marbles tang sight.  28" barrel.   
It came with a box of 50 rounds of Peters and W.R.A. .32 Ideal ammunition, perhaps reloads from years ago, old timey rounde top primers. Will see about more brass from Rocky Mountain Cartridge. Learning Ideal 32359/323059 and 32369/323069 bullets molds would be good to use - just need to find them now. If anyone has other input for cast bullets, load information and comments regarding this cartridge, would greatly appreciate the sharing of some information. thank you

Beautiful Low Wall!

Very nice indeed.

WP proof marks were introduced on rifles some time in 1905.
They were also added to guns sent in for repair after that date.
They are always present on both barrel and receiver (a good way to check the barrel has not been changed sometimes...)

Beautiful gun in excellent condition. I'd love to add one like  it to my little stack of low walls...

May mean it was sent back for some reason. When Winchester made for whatever 
reason an enginineering change that became the standard and anything that was worked on had to be held to that standard. Had a freind that years ago contacted Winchester to rebarrel Hiwall action he owned to .22 Hornet. Their response was no problem and a price. Now this was a beautiful Color Cased double set trigger action that was in "As new Condition" So he delivered it to the Factory because he at that time lived in Connecticut. They sent him a card a couple of weeks later that it was done. When he got there they brought out a Rifle that was newly Blued and had the W P proof stamp on the reciever bridge
which had not been there before. He raised all kinds of hell over it, so they got the Supervisor from the custom shop down to explain and he said they were required under company rules to bring any rifle that came in up to the current standard. Now by this time Winchester had stopped using Color Case finish and rifles were Proof tested and properly stamped and Blue was the standard finish and if he had told them that he wanted to keep the Color case they would have had to refuse the job. If your rifle was built in 1905 then it would have been a Blued Rifle and should have had the W P Proof stamp. They agreed to update his rifle to serial # as being done at the factory. So it sounds like yours is correct with a 1905 manufacuring date. Any how what you have is a beauty. HTH Regards FITZ, OLD TUCK.

Don't risk firing that old ammo.  Maybe corrosive primed, may be mercuric primed.  Second case can be very hard on that almost-unobtainable brass.

opps...    
You're correct, mold number should be 32360/32360 thanks

I lined a shot-out Stevens 44-1/2 with a TJ’s 0.323” liner and chambered it in .32 Ideal.  I reworked the block and firing pin to centerfire (with difficulty).  The twist may be tighter than your original.

I’ve used the Ideal 31949, shortened to 136gr, the Hoch 32359 clone (323135) at 135gr, a real Ideal 32359, and a 178gr Hoch stop-ring .32 bullet.  Powders have included Olde Eynsford 1-1/2 Fg, Swiss 1-1/2 and 3Fg, Hodgdon Benchmark, IMR-4198 and SR-4756.  I’d suggest you start with the loads in Cartridges of the World; the 4198 charge is a pretty good one.

The other powders (besides the casefulls of. ~25gr of Black) are pretty much cut-and-try for the individual experimenter.

Generally I’ve gotten 4 of 5 shots under 2” at 50 and 100 yards with Lyman tang and Stevens blade front, spoiled by a flyer enlarging the group to 4” or larger.

I think the main problem is that I have failed to make a sizing die that allows a slight friction fit of bullet in shell.  I don’t want to size and expand the RMC cases I have; turned cases don’t handle that well, and those were expensive shells.  Some of the bullets more or less recede in the shells upon chambering, some do not.  Lead time for a commercial die set is illustrative of the phrase “Life is too short.”

I’ve been doing a lot of the routine load work with expanded 7.62 Nagant pistol cases.  Blown straight out, they come up a little short, but they do work and extract.  Fiocci, or whoever made them, left them very brittle, even with a couple bouts of annealing, my dozen range trips have reduced the number I started with by half.

But I got the baggie of 60 of them cheep at a gun show, so I’m not too outraged.  I wish Starline would offer their Nagant shells unnecked and untrimmed; they’d make a decent Ideal basic case.
