17 Hmr Bullet Head Jamed In Chaimber

[PLEDGEY 496]

Then put it on guntrader, along with myriad other hundreds of people who realise what a pile of crap .17hmr is

Yep, mines going up for sale. Had about 4 jam in the barrel, loads of cracked cases and I find I use the .22lr more anyways. It's money sat ion the cabinet most of the time. Thinking of getting an AA S410 FAC air rifle instead. Cheap to run and loads of fun :-)

I can't see any excuse for duff ammo though other than money saving and quality control.

 

Wouldn't the companies rather charge £14 per 50 instead of £12 per 50 and produce faultless rounds?

 

There must be ways to prevent duff ammo in the 1st place and ways to prevent any rounds that circumvent the initial measures from leaving the production line, eg weighing, Xray analysis of casing etc.

There is no financially viable way of solving the problem of split cases on the HMR, it is a basic design/technology flaw of reducing neck sizing without being able to anneal. Whilst throwing money at this problem in the form of much tighter manufacturing tolerances may well reduce the incidence of split cases, it will never solve it, (with technology as it stands today) that will also slow production and increase costs substantially.

 

As regards any other issues that will be quality control.

 

This is well known and has been published many times..............

 

From Bob Palmer at Hornady, Published in Shooting UK 2007

 

............... When they make the cases they draw the case out to a .22mag case that has a straight wall. Then the priming compound is put in the rim of the case. The case is spun to put the primer evenly in the rim.

 

After the priming is complete the case mouth is reduced to the .17 calibre to hold the bullet. The reduction process, however, puts stress on the neck of the case. They obviously cannot anneal the neck of the case to relieve the stress because of the compound in the rim, so from time to time you will get a case that cracks. Some batches may produce more splits than others. The chamber pressure on .17 ammo is so low that it does not hurt the chamber on the rifle.

 

They have tried to anneal the cases more before it's formed to .17, but this did not eliminate the cracks altogether. If the cracks were minor I would continue to use the ammo. The cracks do not affect the accuracy of the round and the brass is not reloadable. From Bob

 

 

A bullet stuck in the chamber/barrel will most commonly be a result of no powder in rim or case, either or both, whilst a split case prior to shooting may also give this issue, it will tend to be rare, and generally if the ammo has got damp via the split, properly stored ammo should not get damp! There are always exceptions, but bullets stuck in the barrel are usually a different problem to split cases. Personally, I have never had a HMR stuck in my barrel, but have 75+ split cases now that I know about, I have had .22lr stuck in my barrel, but never a split lr case!

Between me and my brother we've seen 1000 rounds of Hornady hmr and not one of them was defective.

 

I really have'nt a problem with it, lol.

I've never had a jam but had cracked cases. I zero with the cracked cases and still never had a jam

I just spent the past half hour examining a few boxes of Hornady .17 17gr v-max All the same batch E05R15, I have had them for quite a few months.

 

350 bullets in total

1 bullet had a deformed head - I have no doubt that it would shoot ok but feel sure that it would be a flier, never noticed one quite like it before.

37 bullets have a fine crack in the neck (call it 10%)

312 bullets appear perfect.

 

After shooting several thousand bullets I have never had one stuck in the barrel or a misfire caused by a bad bullet.

 

If the weather is ok tomorrow I will setup the Chronograph and see if there is any difference between the 'perfect' bullets and those with cracked cases. My guess is that there will not be any difference.

Federal HMR I noticed cracked cases with mostly,

 

Hornady and Winchester were very rare.

I use cracked cases to test zero before hunting. They've always seemed fine and consistent with none damaged ammo. Never had any jam but I do carry a rod in the bag just in case

Hmr fixed naw hopefully have no more problems love the caliber tho grait fun gun

[celticrusader 78]

Truth be told its a finicky round which needs the rifle its used from to be serviced (barrel pulled through and cleaned) after only a certain amount of shots as even after a few the fowling is a large difference compared to that of many other calibres and this is what some people do not realise when using hmr, I can only come to the conclusion that this maybe and is the case predominantly for rounds lodged in the barrel.

In the past 2 years I've put roughly 1000 rounds through my hmr and never once experienced anything of the sort whilst using all of the infamous brands.

I'm still amazed with all the problems that the 22lr ammo will chuck up and the way people complain about the hmr.

I clean mine regularly and would always advocate that, but there are others here who say they never clean theirs and they shoot fine!

 

Barrel Cleaning will seldom if ever be the reason bullets get stuck!

 

I checked the zero on mine at 100 yards at Bisley yesterday as I'm off to a fox job this PM, 5 shots, all V-Bulls and two split cases out of 5, split cases seldom have any effect either! !

[celticrusader 78]

Well I get it with most rifles and I dont bother with my 22lr as its not effected but the copper and carbon left in the barrel on a hmr sends them all over the place in a short space of time.

[shropshire dan 467]

I clean the hmr every 100 rounds. I never clean the .22

I Boresnake my HMR after every outing. Some people say this is not enough, but mine is still spot on.

On the subject of split cases, I've had one bullet still in the bore at the crown end, or silencer, that was hit by the next bullet, after a misfire. (I know I should have checked the bore before chambering another round) I also had a round stuck two inches up at a later date. Fortunately I checked the bore this time. This was an old batch of Remingtons with cracks.

Recently I've been using up some Hornady blue tips with no problems, only to have a click-bang and a shot that fell short of a rabbit. Taking the case out, it was badly split, about 6mm long. Checking the two dozen spent cases in my pocket, there were nine with splits, but had been unaware there was a problem, when fired. My ammo is stored in the cabinet at my house, which is not damp, so can only assume the damp got in out in the field.

[celticrusader 78]

I broke a bore snake on mine and it wasn't cheap and I couldnt get it to do what I bought it for...that said I decided to never do it again and nowI do it with a rod.
