Hey Stix , what sort of crivac machine do you use mate they look nice bags thick and neat

cocked bolt
uncocked bolt
this bolt has the firing pin set at the recommended 2mm
bigfellascott wrote:This is the Howa bolt
I also decocked the bolt and the firing pin protrudes about 2mm or so but I can't see how it will set off a primer because it is resting against it, it really would need force ie being cocked and under spring-loaded tension to set it off as far as I can figure out.
As I've said I've carried my rifles plenty of times with one up the spout and decocked and never an issue and I just can't figure out how it would set it off without some sort of force (spring loaded tension on the pin) to make the primer detonate, I pushed on the back of the firing pin with a screwdriver and there is no movement whatsoever so it can't strike the primer as such, not sure about other firearm setups but I think this one is ok certainly has been all these years

you are right blade, we can get complacent as we get experience, its not hard to be safe

To clarify, he carried the rifle that way initially, which almost certainly negated the safety by allowing it to be disengaged against his pack, or anything else while it was out of his control - even tree branches or brush could disengage it very easily. And just as easily, another branch could pull the trigger, while he is waving the muzzle around.
He then took the rifle from his shoulder into his left hand, without checking the safety, or keeping it pointed in a safe direction, when he slipped in the slush, and the rifle fired. Falling or dropping a cocked rifle allows many uncontrolled interactions with the trigger that could fire it, branches, clothing, fingers, etc can all inadvertantly find their way into the trigger guard during a fall.

For those unaware Its worth noting that many rifles the extractor only picks the round up when the bolt is fully closed/on the down stroke if you get me....
Ive been in the scenario where game is seen & a round chambered but leave bolt up to be ready...
Game disappears then some banter/or game is shot & another round chambered with bolt up again, bit of chit chat/banter, forget a round has been pushed down the chamber...
A complacent "check" is done by sliding bolt back & forth without closing the bolt, inadvertantly leaving a live one in the chamber that is not realised until another round needs chambering--& this could be too late...
This scenario is a great example of the need to be muzzle aware--particularly if rifle changes hands after a complacent check & someone goes to collect the fur.
I always work the complete cycle of the bolt to ensure no round is left in the chamber...particularly spotlighting when its hard to glance down the chamber.

I dont have the pictures but on most firearms the cock on opening. You will see a litlle part of the back of the firing pin sitting it a slight indent at the top of a ramp. When you close the bolt it moves the small bit of the back of the firing pin from the bolt stopping it to the sear of the gun that holds it in the same position backward. as you close the bolt you are moving the back of the firing pin back across that ramp which helped move it back against a spring to hopefully the fully closed bold position which will give that firing pin clear access to move forward when released.
If the bolt was only closed half way the back of the firing pin may be in line with half way along that ramp but still held back by the trigger sear somewhat. If the trigger was pulled in this state the firing pin would move forward it may move enough to hit the primer the locking lugs may not be full engaged. Its impossible to come up with all the outcomes but a lot of them are not good.
