Lot could be said but to keep it down to whats important. One shooters opinion only.

No real reason to crimp any single shot cartridge used on the target range.  I shoot a monthly match that requires fixed.  Most people that shoot winning scores just flare the case with a Lyman M die or it's equivalent and roll the slight flare out. Plenty of tension to hold the bullet in place without a crimp. Perhaps a long hunting trip with the cartridges in a belt crimp could be good.

Powder complete burn is a function of using the right powder. Guessing 80% of the 32/40's shot in competition use 4227 and it burns fine with little or no case neck pull.  Strong crimp is a good way to get the wrong powder to fully ignite. If not 4227 something that's close on a relative quickness chart ought to do fine.

Other thing is single shots no real reason to worry about O/A length either. Seat it out until it touches the lands  and shoot them all the same length. I don't even know how long my fixed 38/55 loads are. I just seat them until they touch.  Don't worry about were the bullet sits in the case. It's not important.

I use Lee dies for many cartridges. Pistols with cast bullets Lee exclusively. Lee  Factory crimp on all my lever action loads. 30/30 45/70 32/20 & 38/40. I don't take great pains with Lever loads, you need to crimp them and Lees factory crimp covers up for inconsistent case length.    My opinion is Lee is not the best choice for target loads in straight taper old cases though. 

My 32/40 & 38/55 dies are a mix of Lyman factory, M I polish down to the proper size mostly and C-H made to order.  It's just a different standard of precision required for a single shot target rifle and economy dies made for the mass market won't do for me.

What's important with fixed is getting the right  bullet up to the lands and launching with minimal disturbance.  That Hoch bullet is a good one give it the best chance by not disturbing it any more than you have too.

Thanks for the input.  Last night I decided to dump my mix of reloads and start from scratch, i.e., re-necksize, load 14gr IMR4227, OAL 2.70, then check looseness of bullet.  After this batch of resized bullets, I'll not resize, just lube, and see what that gives.  I have a Lyman .323 sizing die, hope its not too messy.  Otherwise, I'll have to go to pan lubing.  After that I'll drop back a few grs and see what each will do to group size.

That was just the thread I have been looking for . Thanks Guys for answering some of the questions I have been thinking about. But didn't know how to ask . I have Two 32-40's one I will be Breech seating and the other I'd like to use fixes loads. Thanks again , Bruce

Single shot hunting is limited to prairie dogs unless it's a .32-20, which is for bear.
I never shot any black powder in any load I've made up for that rifle, fixed or breech seated. In it's youth, it must have been tormented that way (smokeless not being invented yet), but since WW2, from whence I know its history, only the good stuff goes through its barrel. No separated cases.

Most the time my fixed loads work best if touching the rifling. But I can't say that's 100% of the time, as occasionally I get better accuracy with a little space away from touching the rifling. So it's tough to say it's always going to be best to touch the rifling in every situation.
I don't crimp the necks on my single shot loads. Just enough tension to ensure the bullet doesn't move in the case neck.

When I was shooting my 1885 High Wall (original not a repro) for Cowboy Action Shooting side rifle matches I used a Rapine 165 plain base boolit in slightly short re-formed .30-30 cases.  I used an RCBS neck expander die with a .321" plug and flared the cases just enough to seat the boolits.  I seated them so they were just "kissing" the rifling and adjusted the seater die to remove the flare, but didn't use a crimp.  With 12.0 to 12.5 grains of 2400 that old High Wall still shoots WAY better than I can hold it ...

I'll give that one a try for sure  , I just found a whole bag of Cleaned once fired 30/30 Brass . I just wish I didn't have so many other Summer Projects going on at the same time. The Rifles I'm Shooting are originals also ,but one is an Original Hopkins & Allen and the other is a freshly Relined Remington Hepburn done by a forum member . So I have two different size Barrels .I'll probably end up using the Rem. Hep. more once I get started again. Of course its the Ugly one and the H&A I got off Gun Broker and its Nice.
I'm going to have to make some time to Load & Shoot with all of this new found knowledge from this thread. I'm looking foward to seeing the results . Thanks Again ,Bruce
