Hi Danny,

I know that in the past with misfires on practice cards it has never been a problem and if it misfires again then you get a new round. If it was in a competition then it is always good to use another round and have one on hand.

I think that if you are using someones name on a public area that it is best to give the whole picture or discuss it with them first eh!

I think it is about time that warmers were included in the time for the event. And crossfires and overload penalties shoudls till apply.

Just to understand where you're coming from, why do you think warmers should be included in the time?
I doubt anyone would disagree with the crossfire and overload penalty.

Well if it miss-fired and after ejecting found it to be minus a projectile and there was no hole in the target, I'd be checking the barrel alright!
I've had it happen on my old sporting rifle using .22 shorts.


Wheelz, I got a cobba who used to work in an armory, he got a semi auto rifle in (.22 RF). Owner complained that it was making funny sound when fired. When he examined the rifle it had a projectile(s) stuck up the barrel. Long story short - he tried to dislodge projectile but wouldn't move so followed instruction from gusmith book by heating the barrel over flame, unfortunately had finger over end of barrel when it went bang - exit end of finger - ouch!!!! turns out that the bullets had got wet and when fired in rifle only the primer ignited forcing projectile into barrel along with wet powder charge and when the barrel was heated the powder dryed enough to ignite first lot. when I got the barrel to examine with X-rays for the inquiry it still had another 5 projectiles stuck in it with a neat little gap between each just large enough to trap a powder charge.
Talk about a set-up. You'd think after hearing one funny sounding discharge you'd check to see whats going on, not just keep pulling the trigger cause the rabbit's getting away.
The moral of the story, if the discharging sounds peculiar then investigate otherwise you could end up with a bulge in your barrel and lots of stuck up bullets.

I think the principle is 3 minutes for sighting shots and then one minute for each counter (this applies to allowable faults an continueing in a later round). Sure one of the sighters is optional, but warmers are also optionall and form no part of the match as they are not supposed to be shot on the match target. Also if my memory serves me right the principle of 1 minute per shot follows thru into outdoor as well.

Another thing you can check is the firing pin protrusion. to do that you just hold the bolt firmly and rotate the bolt handle to what would be the closed position (clockwise looking at the back of the bolt) to release the firing pin to the fired (forward) position. There should be a reasonable protrusion of the pin but not enough to extend passed the very front end of the bolt. If there is not much of the end of the pin visible this could be an indicator that the end of the pin has worn and may require replacing.
Incidentally, it is good practice to store the bolt in this configuration as it releases most of the tension on the spring. prolonging its life

that is really helpful advice, yeh we have checked the pin that was the first thing dad looked at, when we swapped them over on monday dad noticed that the firing pin on my rifle was bent slightly becouse it wouldnt work in his bolt so he fixed that problem I really hope that solution 2 works, starting to get a little worried. there must be a way to fix it shouldnt there?? or can rifles get to a certain age where they stop working

I Have one more tip for you to consider.
Have you checked the head space. To explain, the head space is the space left between the head of the bolt and the face of the chamber,(the bolt end of the barrel) when the bolt is closed. As the rifle gets more and more use, the locking lugs on the bolt handle and their corresponding recesses in the action wear and allow the bolt to move rearwards thus increasing the head space and of interest to you, as the bolt is allowed to move rearwards so does the firing pin and this lessons the stiking effect on the rim of the chambered cartridge, and this can give rise to your problem of unreliable firing of the primer, urgo missfire.
You could check the headspace yourself but I would recommend you get a gunsmith familiar with you make of rifle (I presume that its an Anschutz) to check it, someone like Harvey Westland who lived out on the Old West Coast Road down your way the last time I knew. Critical here is the space between the end of firing pin in the fired position and the face of the chamber, if this gap is too large then the pin will not stike the rim efficiently enough to cause the priming to ignite, the depth of the dent in the rim of the cartridge is sometimes a good indicator
I do remember Harvey telling me that Anschutz do tend to have a large head space, hence the conditions on my recommendation.
Trying another bolt in your rifle for a while might be an indicator of worn locking lugs etc for you, especially if you get reliable firing.

Hey Wheelz, if you got a Vostock, be aware that they can be absolute B@^^#%$ to re-cock before placing the bolt into the action.

I have been plagued with this problem over the last 2 years,apparently my pin has 2 much head space,hubby and I have been slowly adjusting it and hopefully no more misfires.
I had tried several ways to keep the "Flow" going,eventually I got in the habit of taking 2 warmers in with me, and as soon as 1 misfired I would simply eject it and replace with new bullet..no time wasted and little disturbance..BUT I never put the bullet back in and have another go with it.. Learnt that the Hard way..I put 1 in that had been hit but had not indented enough to fire..and as luck would have it the pin struck it in almost the identical place and I GOT A BLOW BACK THROUGH THE BOLT AND A EYE FULL OF LEAD DUST..REALLY SCARRY!!NEVER NEVER AGAIN. cry

Hey your most welcome, thats what this forum is all about, if we can't help each other out then what are we doing here. I've seen that fix work more than once and seen a lot of hair pulling before hand lol.
Now you can concentrate on those dots.

I had another miss fire tonight pulled the trigger and it when click and there was no mark on the bullet. As there was no mark on the bullet I put it back in and it fired! (it was one of my signers and shot fine)

This has happened twice with my FWB why would that be? and 1st time I put is back in and tried again it would not fire so I give it to Tania van Zuylen and she fired in her FWB and it when 1st time.

Mmmm, firing pin doesn't strike, then it does??? Perhaps you've worn it out already!
I think firing pin/spring for that sort of thing.
We'll have to see what Grumpy has to say about that.
