K Hornet Fire Forming
Folks ,
I just loaded about 25 rounds of new brass , .22 hornet to fireform in my Bullberry .22 K rifle. Problem is I may have gone a little too hot ! I used 11.2 grains on H110 and a Sierra 45 grain spitzer . Also the data showed a col of 1.730 which I think is very short ? How about some feed back from the Hornet experts . Thank you in advance for your time , help and consideration . Semper Fi, Soup |

I think you'll be fine. I use 12.9 of WW296 with a 40 gr. bullet in my 22 KH loaded to 1.760".

When I was fireforming .22 Hornet to Ackley Improved Hornet(30degree shoulder), I first necked them up to 6mm, then sized them down in "K" FL die to position the shoulder in the correct location, so the case would not stretch at the web. The result was perfectly formed brass, no losses.

+2 plus if you have an annealer it's not a bad idea to re-anneal including the shoulder before loading to FF. This seems to vary a bit from one brand of brass to another so a little test batch is a good idea. It's pretty disheartening to load a big batch of FF then start seeing split necks and/or shoulders. Don't ask me how I know some of these things, just take it that after reloading for lots of mostly smaller cartridges for about 60 years I have seen lots of things happen, some not so good.

I had the most loss with RWS and newer Winchester brass, But now knowing about the 6mm false shoulder trick that may solve my issue. Really sad thing I know about and use false shoulders on larger cartridges... Head hung

I start by necking the 8x57, .30/06 or .35 Whelen cases straight in 'one pass', then necking those straight tubes down to position the new shoulder where it should be for a 'crush fit" on chambering.

A thought......
With a PROPERLY chambered rifle, factory loaded 22 Hornet ammo can be fired, and fire-formed to 22KH (or 22AH).
Since the Hornet case headspaces on the rim..........creating a false shoulder should not be necessary. But......consistent rim thicknesses, that closely fit the chamber, would be required. Otherwise.......all bets are off, and false shoulders would be needed. (A side note........in the past, I've made plenty of 17AH false shoulders simply because I had to neck the case down anyway.) Hope this helps. Kevin |
