Yes, I experienced the lopsided expansion now and then myself. Culled more than a few whole boxes. I keep each box of cases (20) segregated from others forever. Noted in my journal and on the box is the high/low and average dimension of that batch to the ten thousandths. Included is total number of firings as well as some other info. I don't load ammo by the hundreds like some, so it's not a big deal to take a periodic check of this stuff if there's any reason to do so. I like playing with my ammo- and cases are a pet with me more than most other stuff. Some hate it, not me. So far, so good. And, Ken Waters has been quite a bit of my learning.

The 1910 REM-UMC catalog provides the following for their  32-20 loadings:

.32-20 Winchester and Marlin, Black and Smokeless     100gr bullet     1325fps
.32-20 Winchester and Marlin H. V., Smokeless            100gr bullet     1575fps

I don't recall that PACO was especially detailed about the timelines for the firearms and the various 32WCF High Velocity loadings.

What PACO doesn't appear to mention is that:

Winchester Repeating Arms did not produce the 32-20 80gr OPE/HP cartridge loading...
     that loading was introduced after production of the Model 1885 rifles had already ceased and any remaining inventory of 1885 component parts were liquidated, and after OLIN and his sons had purchased and absorbed the WRA bankruptcy assets under the WESTERN CARTRIDGE COMPANY.

The REM-UMC 32-20 80gr HP loading, which REM-UMC sold under the Hi Speed label (their earlier HIGH VELOCITY labeled version used the 100gr jacketed Soft Point bullet), wasn't introduced until after the Rem catalogs only referenced their singles shots under the headings of Component Parts, and concurrent with the production of the Remington Model 25 pump action.

My 32WCF chambered rifles and revolvers ARE used for hunting, Gris.
I don't eat paper, and I detest bloodshot meat, which I consider a waste both to the bird or animal, and to those gathered around the table as well.
As others have already mentioned, Ken Waters has provided excellent guidance for many long years now, and will continue to do so, as long as one is willing to open his articles, books, and supplements from time to time.

You don't have Pet Loads, then. It's THE book we are speaking of here. The individual articles were from [u]Handloader[u] magazine and assembled into a loose leaf book, to which supplements could be added as they became available. Later versions were printed in fixed page style. The original already had the .32-20 in it, and the strength of various actions is featured in many of the articles as the need came up. 
Even if you had read the book he co-authored with Ned Roberts there would have been info on that cartridge. So, I believe you have made a mistake in whatever author yer thinking of. Doubt it was Waters.

WOW   

Here I am tuning back in after getting side tracked a bit .

Now I intend to take it all in ..in time.

My purpose for this rifle build is for a quiet  small game getter for the pot and a back yard slayer.
With maybe used on bigger stuff in an opportunistic encounter.
With the  ability to shoot larger weights at reasonable velocity
I like to shoot around the speed of sound for the increase in wind bucking and not have to worry about going into the turbulence zone.
To shoot out at 200yrd mark then I'm not really sure if this case will stand up  to lots use pushing a 187gn @1400 fps if I need to go that fast.
Now 10 reloads is not much in my book.That means I'd use up 5 to 10 cases in a days shooting at the range.
No it won't be a purpose built benchrest gun or perchbelly pronged wonder either.

Not that I'm not prone to trying to shoot  some resemblance to a half decent effort thou.
Something like a more the lines of a english rook and rabbit rifle if i can manage something.

More likely just a std martini cadet  chopped up abomination with original furniture.
I even plan to surface pit the barrel before bluing to make it blend in more with the hundred years of getting banged about and neglected in storage.

FWIW,

I' ve messed around with my30-20 and several heavier (for calibre) bullets, weights between 150 and 175.  All of those propelled by BP, of course at subsonic velocities (1050 fps or thereabouts).  Shoots perfectly out to 200, even shoots very well at 300.
Still waiting for the new barrel to be installed on the rifle, so that I can start working up loads for what will be my new short-range BP match rifle.
