Damage To Swift Moderator By Hmr Bullet

[charlie caller 3,654]

So go on then explain how the chap on the stalking directory who describes very similar symptoms to the op, had his extractor blown off his bolt then? Do you suppose that was caused by mud, or his moderator failing then? No it was caused by the bullet from the first shell lodging in the barrel, just like this instance,what the op said was he pulled the trigger, he heard a click, and having the good sense to keep the rifle pointing in a safe direction, then heard a dull report, then smoke poured out of his chamber, that is not a MISFIRE, that is a HANGFIRE, and one of the first safety lessons you should get taught is if you hear a click keep the gun pointing in a safe direction for 10 seconds as it may go off as does happen now and again,then what is the next thing we are told to do?????? You got it CHECK THE BARREL FOR OBSTRUCTIONS, I wonder why

Just got back from trying out the rifle and moderator. I turned up a new spacer, tidied up the baffles and reassembled the parts. Without adjusting the sights, I had three touching holes on the bull of my target at 60 yards. This gives a zero at 120 yards.

I head shot my first rabbit at 140 paces, then went on to shoot two more at around 120. I had no misfires, or split cases this time out. The sound moderation is as good as ever. I was worried, that the crown had been damaged, but that is obviously OK. Lessons have been learned and will check the bore, after every misfire in future.

These three were all head shots.

Thats one of the problems...... nobody gets taught. Just get a firearms licence and go shooting learning as you go. Just read these forums to realise how misinformed and inexperienced most shooters are. No criticism intended and isn't it good that people read and post, even if it sometimes results in a bit of flak.

I cant comment on the chap from the stalking directory as i have no idea what happend to him. but i do still have the same opinion on this case the guy said at the begining of this that he heard a click then a while later the round discharged, there was nothing in there to suggest that the round had not fired at full pressure.

I had to do a range day recently with defra during that day i had some duff primers in the ammo i had which resulted in 2 misfires and a hang fire, after the hang fire a full barrel inspection by me and the range officer was done. later i discovered that one of the misfires had no powder in it but the primer had failed anyway.

the moral of this storie is that there can be all sorts of things that can go wrong with your ammo, but if the main charge fires there is a very good chance that the bullet will leave the barrel.

You seem to think that if you fire a round down a barrel which already has a round in it, it will just push it out, but think on, i think iam correct in saying that all 17 ammo used in hunting is balistic tipped and that the ammo in use in this case was the same, so ask your self what are the characteristics of this ammo upon impact with a hard object, and what happens with the build up of gasses from the fired bullet and those that make up the gap between the fired bullet and the lodged bullet. this is my opinon of coarse you may think that its a load of twaddle but i bet you wouldnt give your theory a feild test.

You can be fairly sure that your first bullet left the barrel and mod, if you want to think that a few damaged baffles is the worst that can happen if you get a bullet lodged in your barrel you could be in for a bit of a shock should you actually get a bullet lodged in the barrel and then fire another. your hang fire was just a coincidence not a cause.

 

How else would it be possible to get a bullet lodged in the barrel?

 

Genuine question coming from a newbie to firearms.....

 

Good Question, in honesty there are all sorts of varients that could cause a bullet to become lodged in the barrel but it is uncommon. if the powder fails to ignite properly for some reason which i think would be the most common cause, bearing in mind this is a little 17 round it wouldnt take much to push it out, but i dont think a primer alone could do the job, you also have to bear in mind that anything below a half charge would possibly create more pressure than a full charge within the cartrige and anything more than that would push it out for sure. I have never had the problem so have a zero experience of it.

Could be off the mark but aren't 17s prone to barrel fouling if so does that not mean there must be more friction and more likelyhood of a bullet jamming after a hangfire?

[rimmer 33]

you could be right, but i would have thought that the previous shots would have cleared fouling, but i have seen it in an 81mm mortor round which failed to drop to the firing pin.

i was always under the impression that 22 was the dirtiest ammo out there but i have never heard of bullets getting stuck, but although i have had some truly awful 22 ammo, the stories i hear about 17 ammo is that its common place to have split necks and hang fires.

There's on bullet here that's shot 3 times before it finally fires plus 4 other misfires from the same box!

 

 

 

I'm still unconvinced myself that the bullet would lodge in the barrel without some other bore issue 1st.

 

I still believe it may have been a combination of factors such as low velocity hang fire that got stuck behind a baffle that had in some way become damaged or slightly out of alignment followed by the 2nd round impacting although equally the 1st round could have left the barrel and the 2nd round just hit a problem with the moderator.

 

Either way, one thing that stands out to me is the fact that "one bullet hit another evidenced by the fireworks" - as I said above, lead (and plastic) don't spark. Only steel does that so all that indicates is that there was steel on steel as the moderator was destroyed. It doesn't indicate or deny the presence of a 2nd bullet in the barrel.

15 mins 31secs of my life i will never get back !!!!!

I Agree with Rimmer! If their was a round lodged in the barrel and another shot was fired, the aftermath could be deadly, and a high chance of maiming the user resulting in loss of fingers or their face resembling a chewed up toffee. The OP got off lucky this time, he could not be here now, or not typing because of the loss of his fingers. Firing another round down a fouled barrel is a no no, the pressures are crazy, how the barrel didnt blow or the chamber etc is very lucky, which leads me to think that the first round must have just exited the barrel. This could have been a lesson that was learnt too late....

this guy left his bore sighter in the end lol get my point??

[Craig83 52]

Ill ask a mate of mine tomorrow, who is a armourer here on camp. If he don't know it no one will lol

[walshy0988 28]

I've had a firework so to speak from one of my rounds in my.17 the bullet still left the barrel it was more of a fizz than a bang but still checked the chamber. As for the split cases I bought 4 box and out of the 200 rounds I got 71 with split cases un fired I was told it was a CCI problem and it wouldn't affect the performance of the round but I didn't agree and they was returned.
