Jerry went from his 33-47 and his first 250 to his 25WCF and has never looked back. And no one in our group has used small cases in a 33 or 32 in our Monthly matches for the past several years that have now since passed.

JackHughs,
Thank you for chiming in. As I have said to many from my beginning with the .32-20CPA, you have been my inspiration and long distance mentor. I truly enjoy passing along to other shooters of the .32-20CPA whatever I've learned from you and a handful of  others who have helped me over the past few years. Regardless, I must echo what you and JLouis have always said, ............. to excel with this (and I feel any) cartridge takes never ending trial and error development in addition to plenty of range time. No one ever claimed success would be achieved easily, but I find it well worth the effort. Thank you again for being there to share with us other shooters.
Sincerely,  Ray_H

I assume the mold Paul supplied was 0.323" or greater. If so, was there a problem with hard breach seating into that smaller barrel? Or did you finally find accuracy with a different bullet? -CW

Here's a bit of follow-up to my previous post. This mainly covers the rifle - loading will be next.

The CPA benchrest fore-end was too short.  A friend did a masterful job of extending the fore-end by approximately 2 1/2".  The extra length made it possible to find the best placement of the fore-end on the front sandbag rest.

The through-bolt stock was also problematic.

A Stevens mainspring is a long, flat spring with one end secured to the action near the end of the lower tang.  Cocking the hammer causes the lower tang to flex which, in turn, causes the rifle to flex at the wrist.  Try this: Place your Steven's or CPA rifle on a solid rest and aim at a bull with the hammer uncocked. Now cock the hammer and you will see that the POA has moved upward. This movement cannot be eliminated but it can be minimized by adjusting the mainspring for a softer hammer strike.  However, too soft of a hammer strike will result in erratic ignition and vertical stringing.

The through bolt mounting system solidly connects the top tang with the lower tang.  Tightening the through bolt "loads" the lower tang in a manner that interacts with the loading caused by the cocked mainspring.

So, a great deal of trial and error was required balance the tightness of the through bolt with the adjustment of the mainspring to assure a sufficient hammer-strike, minimize flex at the wrist, and to assure that the triggers work consistently.  I experimented with three separate mainsprings, each of a different size and shape until stumbling upon the best combination. 

Again, I'll do my best to describe the loading technique as time allows.

Thank you Jack Hughes I know it's taking allot out of your time and I am also copying and saving it all should it be needed at another time. Something I should have done for this group as you were sharing it in the past. This time around there will be no need to share it again as I will now be able email a copy when the question is again asked.

One thing that I would like to say about case separation, regarding the 32/20 case, is that I believe, at least part of the problem is action strength.

I first chambered a 44 Steven, with a lugged hammer, in 30-32/20, for my wife. She could get about 2-3 firings with Winchester cases and up to 10, with Remington cases, before separation started. The load was breech seated 184 gr bullet, with 8.0 gr 4100, 1250 fps. A fairly light load. I couldn't get the accuracy I wanted with it, using a Wilson 11 twist barrel. That action is now my BR, 22 LR.

I had a small thread HW and put a Douglas, 12 twist, 30-32/20 barrel on it. The load for it is, 10.2 gr 296 and 9.5 gr #9, with the same Ron Long 184 gr bullet. The velocity is 1410, in a 26" barrel. This load with a 30 cal barrel, won't be to far off a 32 cal barrel, pressure wise. But, Jan's load should have a bit more pressure. 

With everyone having trouble with case separation, with this brass, I re-swaged 357 Mag brass to 32/20, anticipating I would need it. I sent some to a forum member to try in his LW and I believe he said it lasted longer but, still separated. Maybe he'll chime in.

On to the HW. I started her out with 10, Rem cases and with the above loads, my wife lost three of them, in a 1.5 year period, after switching to the HW so, even though she tried the Mag cases, I never had her use them, because I only made 3 for her. I think the 30 cal version would be more prone to separation, because of the more pronounced shoulder to neck junction.

My summation is, that with a strong action, the case separation, isn't a big problem, based on my using these cases in a HW. The 44 1/2, is a fairly strong action but, I think it gives enough to let the separation problem happen.

I'd be interested in other shooters experience's with a well headspaced, higher pressured, 32/20's in HW, Borchardt, FBW or Hepburn's.

anyone try annealing to maybe allow quicker/better fireform (ie Jack's first three firings-no immediate accuracy comment) for this round?

What case length are we looking to trim to?  Maybe a stupid question but I am willing to ask

Is the expander die being used after each firing?

Thanks to everyone taking the time to contribute to helping myself and others with loading help.
