    17 hornet

    Hi all
    I am just in the process of looking for some 17 hornet brass to reload and also Accurate 1680 / Lovex D063 but no one round here seems to stock either , I've looked through the posts and rung around to places like Malmo Guns and westlander along with all local areas.
    Now I will try and reload the factory ammunition that I use but I still have the problem with the powder ... I have the option of n120 or lilgun but would prefer the accurate 1680 / lovex D063 as n120 can be a little low on speed and the lilgun a bit volatile with slight increments in power showing pressure signs .
    So my question is does anyone of you guys know of where I could source the above , cheers .
    Regards
    Colin

    Personally, if I was starting out again ,
    I would use CFE BLK & resize .22 Hornet PPU cases,

    As I learnt the hard way with Hornady brass and various powders !

    17 Hornet

    Hi Treetop

    I would choose the CFE-BLK but there's none in the country and Edgar brothers say that it will not be until late summer before any shipments so still looking cheers .

    All Hornady brass has issues with primer pockets,
    After a few reloads they get really loose & they can fall out !

    Also,

    17 Hornady brass - factory ammo, there were 2 different types, the early ones had shallow primer pockets and then Hornady changed primers, they also went through a stage of crimping them in.
    So, not all 17 Hornet Hornady brass is the same !

    PPU ( privi ) and RWS are the best for this ..
    And you won't be disappointed!!

    Good luck even getting 22 hornet cases. No one has them in stock! Do a search online. There is one company selling ww brass at 40 quid! I've been chasing krank for ppu brass since August!

    I've noticed one or two of my 17 Hornet (Hornady) cases have loose primers after only one/two firings. Can anything be done about this? I know the primer is against the bolt face but is it safe to shoot them?
    Thing is, I don't know if they're from the reloaded Hornady ammo or the once fired new Hornady cases.

    In short - NO

    The brass has stretched and it's finished ...

    Obviously if you look at what load your running and it's a ' hot' load, then, yes.. You can back off the load - thus lowering the pressure in the case, which may make the brass last longer... Also you could invest time researching the size of primers and see if you could find one that is slightly larger than the one you are using.
    Ultimately, Hornady brass does not like high pressure & is known to stretch in the primer pockets


    As for .22 hornet brass, look about... Some shops have it !

    I doubt the brass has stretched. Only been fired once with 9gr of LilGun. Hodgdon says start at 9.7. Others have said that's too much and have settled on 9.1 - 9.4gr. Apart from that it's only one or two that's loose. I did notice some were harder to get in than others. This is with Fiocchi primers which fit the Hornady shallow pocket nicely without poking out.
    So assuming the brass hasn't stretched can anything be done? How much are the dies to neck down the 22 Hornet cases?

    You have exceeded the pressure limit!

    Hi,
    If your primers were a tight fit for the first reload and now have become too loose then you have likely exceeded the pressure limitation for this load/brass as this combination has exceeded the ELASTIC LIMIT of the brass and consequently will not "spring back" after firing. First step would be starting with a "new case" to mark a spot with a maker pen (thin mark) just in front of the rim, but as close as possible to the rim and accurately measure the diameter at this point (and as close to the rim as possible) using a very accurate THIN edge caliper; recording this measurement (to better than 0.001") and then firing. Then if your measurement has increased by greater than say 0.0002-0.0005" then ITS TOO HOT FOR THIS COMBINATION. Of course the larger the case then a slightly greater increase could be tolerated. My K Hornet pushes 40gr. Nosler Ballistic Tips at 3250 f/s using Win #296. Case life is more than 10 reloads before I see any reduction in force when seating primers. As an aside years ago I tried Hercules #2400 in the another K Hornet starting with a mild published load:- it "blew" the primer! Do you have access to any other brands of primers as different primers may be worthwhile experimenting with as they may provide a more gentle ignition.

    cheers

    You could try Andy Allwoods in Bracknell for Accurate / Lovex powders. When I spoke to him a while back he could get them in. Or you could try the UK distributor www.westlander.co.uk
    I have found that necking down 22 cases can work by trial and error. Using a Redding seeater I have necked down fired 22 Winchester brass with the plug removed as a first step, then full length sizing as a second step. This method did not work for new PPU brass, but using a Redding FL bushing die with the bush removed first and then again with the bush did work.
    Both methods require plenty of lube and going slowly on the press, feeling for resistance. If you go too quick then the cases will crush.
    Either method makes brass that will be too long to and it needs trimming to about 1.35" IIRC. After firing it will form and shorten to the required 1:34". Before firing it will need annealing or the shoulders will split. Using a socket in a cordless drill I rotated the case necks over a propane torch fine flame until I could visually detect a slight glow in the metal. I let them air cool afterwards.
    About 9gn of Vihtavuori N110 with a Kranks 17gn HMR Vmax gives around 3500fps which is a usefully accurate fire forming load.

    Without being rude, the brass HAS stretched beyond its useful size, which is why the primers are loose.. ( pjinox has given a very good method of checking ).

    After using lilgun in the early days of my 17 hornet reloading, I know that there is not much room for errors as the pressure increases very rapidly... As for Hogdons data, I would treat that with caution, as there are loads that would agree with me that it's far to higher load...
    There are lots of reports now coming out of barrels showing wear & pressure signs through the use of lilgun.

    Personally, if I was starting out again I would try looking at Hogdons CFE BLK as a good powder,
    However, I use IMR4227 as it was one of the early ' extream' powders & as such has good stability with Temp difference ( a big issue with small cases & high pressure loads ) also, from my calculations there is no way I can over pressure the case, as I can't fit enough powder in it - even a compression load won't !

    The next thing you can look at is seating depth - this works in 2 ways , increase the lenght lowers the case pressure, but if the bullet touches the lands then you will have a vast increase of pressure,
    Be careful when chasing the lands, as the bullets are not that accurate & uniform from batch to batch, so what you may think is 0.02 off you M actually find is touching !
    I have a CZ, and I load to Mag lenght as my max, as the lands are way off & I find the extra lenght is great for my group ..

    When resizing .22 hornet, there are various ways, I use a 'tween' die that starts the neck off, 1st at .20 then I turn it over & run again at .17 before I then Full length size..
    I also use a lanolin mix to lube the cases & then sonic clean to remove after I have trimmed & sized

    Others find that they can use a seating die to start the neck off ( as mentioned on here by Guesty ) likewise as he says, anneal after you have sized ...
