Split case shoulder .17 HMR

[danebrewer10 6]

Hi all, I have a problem here, has anyone else experienced split case shoulders and nexks on their spent .17 HMR cases? here are 4 pics of each "type of split, they are all federal premium, of which I n=have shot around 150 of or so and about 40 or so of remington accutip and hornady, the last two don't appear to have split, but I have fewer cases of those anyway, I was wondering whether the chamber of my rifle is too open or the cases too thin? anyways here are the pics-(you can see how many rounds I have shot(or at least collected) that is a jar in which you get glace cherries, so you know how big it is)

 

 

 

 

 

 

there are three of each of the "types" of splits so three of the kind where there is a tiny split in the shoulder, three where the split expends to the base of the neck and so on...

 

any ideas would be great!

Cheers

Hi there:

Don't worry is the first thing.

I reload loads of ammo and split cases do worry me, but for one shot throw away rimfire's no problem.

The brass is the issue here, and the original manufacturer (OEM) here is using 'crap' brass and it is either to thin or work hardened or a bit of both.

I would send them some split cases, with a moaning letter, you may get some 'freebies' on the back of that?

Your rifle can contain the results of splits easily, the brass is only a convenient container of the bullet and powder anyway, so carry on regardless!

When I had a 17hmr I had several missfires with Remington ammo, were the primer fired but the main charge didn't fully ignite, the bullet went 2" up the barrel, it's just as well I knew what had happened and didn't try another one behind it!

Anyone else had this?

i saw squib rounds happen in centre fire before but never rimfire, A very dangerous situation indeed,

 

always worth checking whenever doubt is in the mind as to where the round went....?
