+1 on Doug's comment. Use the shoulder and neck size only after fireforming, even in the standard Hornet.

SNOW ACCUMULATIONS: TOTAL SNOW ACCUMULATIONS OF 2 TO 4 INCHES ARE EXPECTED FOR LOWER ELEVATIONS AND 5 TO 10 INCHES IN THE MOUNTAINS. * WIND AND VISIBILITY: GUSTY NORTHWEST WINDS 15 TO 25 MPH WILL DIMINISH THIS EVENING. VISIBILITIES WILL BE REDUCED TO LESS THAN ONE HALF MILE AT TIMES. We are the lower elevations by the way. She's a gopher killing machine Jim but 25MPH blizzards really knocks her off her game plan and make her think about reading a good book. They are safe for a while Amigo but hurry up before the weather breaks . We're both really looking forward to your arrival but we'll wait to hear from ya.

Considering the difference in case lengths - I do not recall mention of trimming prior to fire forming in this thead - maybe I missed it?

I didn't go into the process of setting up the cases Daryl and you are certainly right that they do need trimmed before fire-forming (quite a bit actually). After being taken down to .17 and ready for fire-forming I've found that the trim length that finishes best for me after firing is 1.337. 1.340 is the max case length and the trim to length is 1.330, keeping in mind I have formed all these with already fired brass there is a little shortening on forming but not as much as if it were new unfired for sure. After forming I'm ending up at 1.334 or 1.335ish. After they are all formed I'll trim the lot to 1.332 and as you know with neck sizing only of multiple times fired brass I probably won't have to trim em again in the foreseeable future , that's the kind of trimming I like best.

Daryl I forgot to add two things about trimming the unformed cases. First thing is that the initial case shortening was done with a chop saw. Second is, if you use a Wilson trimmer like I do you need to use a .22 Hornet case holder on the finish trimming after the cutting cause before firing the back half of that brass is still .22 Hornet.
Easy process really and well worth the effort. Not sure where I'll end up with the velocity in a formed case (don't much care either) but I do have 1/5 grain more capacity in the formed WW cases than I get in the Factory fired cases. I have a hunch it'll be to close to the .17 Ackley Hornet to tell a difference shooting it. I sure like this little critter , wish Hornady wasn't having all the problems with the factory brass, makes is awful hard on the non reloader and it's sure putting a wet blanket on a neat little round . I'm sure the brass and ammo situation will eventually be resolved but the window of opportunity on new rounds doesn't stay open very long.

As for trimming, I looked at the normal cartridge length which is 1.350" for the 17 HH and the trim to length which is 1.340".
I considered trimming to 1.350" and then fire forming but like Doug found the formed cases came out shorter than the minimum spec. This is just me but I hate shooting short brass in a chamber. As a result I went with 1.355" which still chambered easily in my rifle (which maybe says something about the normal 17HH chamber length in a CZ as well as just about any other factory rifle chamber) and found that the five cases I formed went from 1.355" to 1.344" to 1.346" which fell right in between the SAAMI min and max lengths for the cartridge. I'm not saying one way is right and another is wrong. That's just how things worked out for me using a semi-educated guess, but I fully expected similar results based on the fact that considerable changes was going to occur to the cartridge. -BCB

BCB I think as new as this round is the standards are different depending on who ya talk to and where ya read . In Westerns loading manual (which is where I got my info) they say the case has a maximum length of 1.340 and a trim to length of 1.330. I just called Hornady and talked to a tech and the one I got today stated the max length is 1.350 like you said and a trim to length of 1.340 which is the max length in the Western manual ! Maybe I'll call em tomorrow and see what that guy will say .
I too like as much neck as I can have. Time to measure it myself in my gun I guess, it's tough being lazy .

Being old like you, I understand lazy, Doug.............
I had picked up a new copy of the Hornady #9 Manual last week and it shows 1.350"/1.340" in it. That's what I used as my source. Since it's in print, maybe all of the phone techs will be on the same page... I haven't looked at SAAMI specs to see if they agree or not. I do know my CZ will easily chamber 1.355" brass from my playing yesterday, so using that old TexMex expression we're both familiar with: Quien sabe...? -BCB

"Nadie me imagino" BCB .
I wish I hadn't formed trimmed and loaded all my brass cause I'd like to see at what point the case length actually impinges on the bullet release. Oh well, one thing is for sure, I'll sure not have to trim brass in the life of that batch . On the serious side, the stuff I formed and fired is longer than Westerns minimum by about half way to their max and only a few thou under Hornady's minimum so even though it bugs me I'm sure it'll work fine.
