Re-sizing 22 Hornet Cylinders


Recommended Posts

It's absolutely throwing it down yet again so I thought I'd may as well do something useful indoors, but have a question for the more experienced Hornet reloaders before I start.

 

I think I may be experiencing cylinder growth in one of the rifles. As yet I'm not certain as when I've fired off the existing loads all cylinders are due for the scrap bin. Some, and now I know not which, have been used at higher pressures than I've now settled on during load development and this may well be the problem. I will know for sure when I subsequently reload the new cylinders which I'm just about to use.

 

Just in case there is a problem, I thought I'd give the following a try so I'd be ready and here comes the question:

 

I have polished my neck sizing die (I suppose you could call it 'blue printed' except the mandrel is now a tad undersize through choice) and I'd prefer to use that for the final re-sizing. I was wondering what would happen if I removed the mandrel from the full length sizer die and ran the cylinders through that first. I figured this would not interfere with the final neck size and would not require any tooling lubricant inside the neck. I've got a load of dead men ready to have a go at but thought I'd just ask for comments before I jump in.

 

Any one?

 

Cheers,

Phil

Are you talking about cases?

 

Spent far too long in/with the armed forces; have picked up their jargon: Yep, those brass bits that the heads get pushed into. ;)

 

PS Couldn't remember when the first mention was and had to go and check. Cylinders were in use some 400 years before brass cases. The term related to the paper roll that held the charge and bullet.

 

As our armed forces have been around for a while and used them explains why the old term usage remains instead of the newfangled nomenclature for this recent introduction.

 

Edit: PS

surely the cases are just fireformed to the chamber so they may be bigger than standard but fit your rifle,

 

though thats just trying to interpret as best I can from the description, personally I'd leave the dies alone and either full length size or neck size

Thankyou, al4x.

 

Not quite that straight forward as repeated neck sizing can cause problems with case extraction and stiff bolt operation. I suspect that the extractor set up - just one slim claw - on the Weihrauch doesn't help. I won't go into detail - I'll probably confuse myself let alone everyone else - but my plan didn't quite work as hoped - but a small rethink sorted it and I'm delighted with the result by using the most beneficial aspects from both methods of resizing.

 

Cheers.

those brass bits that the heads get pushed into.

 

Well I understood the cylinders thing but heads? HEADS?! Aaaaarrrgggh! :crazy::rolleyes:

 

I found that high pressure loads in my Hornet did result in hardening/splitting issues with the brass. I guess it's because with each size they were pushed around a bit more? I think your idea of checking what's going on with the latest loads could be the way forward. At more sensible pressures they don't seem to grow so much and if that's the case you can avoid full length sizing - something that is a real advantage with the Hornet.

 

I guess removing the mandrel from the FL die could help as it will be one less operation for the necks to go through and would also allow you to get the final size just right. With a polished die and a reduced mandrel do you not suffer with tolerance issues though?

Hello, mate,

 

"HEADS"! absolutely an anathema, hence the wink. There's one good reason why the trick with the full length die didn't work, but I may have found a bit of kit which I believe would work and which you may you may have liked if you weren't deserting the 22 for pastures new. However, as they may decide to make a 17 Hornet version, if I get the answer back that I'm waiting for which indicates that my belief is correct, I'll give you the heads up. As you seem to be the only one that knows what the hell I'm on about, I'll PM.

 

Cheers

 

PS Missed your last bit - no, the reduced mandrel is marginal, 0.001"

I was an an ammunition technician and later an ammunition technical officer in the army for 23 years. I never heard anyone refer to cartridge cases as "cylinders".

If you take the manderal out it will reduce the size of the brass drastically and too much!

 

Many thanks.

 

That's why I asked and because of the way the neck is sized with these dies you're quite right as I discovered. It only adversely affects the neck by a couple of thou', of course, but that is precisely what I was trying to avoid. However, as there's nothing new on the planet, I'm not the only one with the problem and the answer it seems is available.

 

Cheers

All i can say is after 6 firings of RWS brass neck sizing lightly with a chamber type hand die i have no need to FL size. I use a fair load of Lil gun 12.2 and push a 45grn pill at 2900 fps (measured). If my cases were tight i wouldn't be able to fit them into the die type i use. A lot of this will no doubt depend on the tightness or otherwise of the guns chamber as the brass can only expand that far and no further. The std .22 Hornet headspaces on the Rim not the shoulder for those who are not aware so you are not having to set the shoulder back every so often to get the bolt to close effectively without undue pressure.

 

I dont wish to labour this point as my thoughts are maybe well known in this regards now but the hornet in its std form should be re-loaded in a different way to say a .243 etc. to achieve high brass life and the best accuracy

Well I am having fun with the old lee die set I aqured lol I managed to break the sizing die oops :(

 

Are you sure? Obviously, if it's in bits, one of which is the decapper pin, then of course you have, but you don't say which type it is. Not everyone would buy a set containing the full length sizer and seating die - for the Hornet, it's possibly more likely to be the collet type sizing die. In this case it may just have seized up and stripping it down will sort it.

Thanks for your input, all sorted. I have to say that at £14 for 100 45 gn bullets which you can propel 2900 ft/sec with 12.2 gns of Lil'Gun for me is decidedly Utopian in nature!

No it's the one with the de capping pin in side I got a case well wedged inside it and followed the instructions to remove it by slackening the nut on top and tapping it out with a hammer. Well the case is still stuck and the de capping pin is now bent and stuck as well. A job well done I would say :/ ow well I am not going to have a paddy about it. Will just get a new one lesson learnt Lil less hammer in future ;)
