Rifle firing when moving safety catch.

I regard safety catches as potentially untrustworthy so I never carry my rifle with a round in the chamber. I only chamber a round when I’m pointing it at something I want to kill. If I lose a few deer because of the delay / noise good luck to them.
i do likewise except i chamber the round with the muzzle pointing at the foreground, having checked safe to do so.
 
I believe that Rem 700 had some issues like this a while back

As for trusting a safety?

I never use one - let alone trust one

Rifle is carried, bolt closed, on empty chamber and eased springs - or with bolt back and my thumb in the gap

The ONLY exception I reluctantly accept is the R8 with bolt closed, round chambered, but with pressure off the firing pin spring using the de-cocker
 
There are times when I have a round chambered, if I'm expecting to be in close proximity to deer. But using a Sauer 101 the safety physically locks the firing pin, plus the safety only releases when the button on it is depressed at the same time as it is slid forward. As said, muzzle awareness is vital at all times.
 
And this is why I love the de-cocking safety on my Steyr and the 3 stage safety on the bolt of my winny.
Both physically disable the firing pin rather than stop it from operating.
Until they don’t. I know of one incident where a Blaser went off as it was being cocked.

I have had a couple of issues with safeties over the years. Once when carrying my rifle with a round in the chamber, muzzle up over my shoulder. We were pushing through some young conifers and it went off. Somehow the safety had moved itself from the off position and the trigger must have caught a twig. Bullet went the air and I hope came down in the North Sea.

The other was many years ago in Zambia. We were hunting a cattle eating lion. i was with a chap who had been a Greys Scout in the Rhodesian war. He insisted on carrying his 375 Brno with a round chambered but with firing pin lowered as he had always done and what the feck did a salty* like myself know about guns in Africa after I mentioned this. He was driving the land rover (an old series 2 ish (lots of different bits bolted together), and it was standing vertical on a strap on the passenger side next to me. We went over a big bump and my ears are still ringing.

*a derogatory term for white africans of British extraction- one foot in Africa, one in Britain and the dangly bits in the ocean.

Personally I carry my rifle without a round in the chamber unless I am expecting to a shot within the next few seconds. In which case it is in my hand.

And I don’t get the lining the sights up on a beast then removing the safety. I always remove the safety with rifle pointing at the ground, then align the sights.
 
Checked for enough of my own FB. I've had a few nd's.
Always been conscious of where the barrel is pointing, a good thing.
Best wishes.
NDs scare the life out of me Smelly - having seen a few at clubs over the years, some of which came to earth I know not where. Fortunately for me the sika was at the bottom of a small valley and I was well above it and on the opposite side. This screengrab foto was a millisecond before the unexpected bang - just as I lifted my cheek off the stock and thank heavens ploughed into the soft bank. Needless to say I was so rattled I missed it with the next two shots….

Safeties are all different. Trigger mechanisms are basically metal levers that intercept by a few tens of thousands of an inch to prevent the firing pin or hammer falling until the trigger is actually pulled letting the sear drop and allowing the hammer / firing pin to fall.

The whole system relies on springs keeping every thing in place. And is doing this all under the strong pressure of the mainspring on the hammer or firing pin.

Safety’s vary in how they work. Some simply block the trigger, others the sears and others the actual firing pin or hammer, and a very few work on all three.

It’s possible for a bit of gunk to get into the mechanism and prevent the mechanism fulling engage - eg the trigger rather than have a proper engagement with sear has a paper thin engagement and when the safety is released the pressure from the mainspring forces the whole mechanism to break.

Another common reason is finger pressure on the trigger whilst pushing the safety catch forward. Very easy to happen if you are not concentrating.
 
I had two similar incidents:
1. Ages ago, young and inexperienced, while checking the rifle (a Sako) before the use I noticed that, having cocked the bolt (unloaded) and sliding the safety "on" , the firing pin jumped forward as soon as the safety was "off". A gunsmuth inspecte the rifle, without finding the cause and, at the end he replaced the trigger group. Month later, while talkingwith some friends, I learned that the trigger group has to be cleaned with a solvent and never oiled. I was the culprit, together with more than one Ballistol drops!
2. More recently, I bought a a Weatherby Vanguard and zeroed the scope in the gunshop tunnel. I found out that the safety could be put "on" even with an uncocked bolt. I liked the feature, because the safety locked the bolt, avoiding the risk of an accedental opening and preventing the risk that that leaves, pine needles and so on penetrated the action. Happy with the accuracy I accepted the offer of a "lightened trigger". I accepted, thinking that he was going to adjust the trigger pull.
Few days later, I went stalking with an "underloaded" rifle, sat in low seat and chambered a round.
A roebuck appeared from a bush. I slided the safety off, pulled the trigger and ....nothing happened. I reloaded, shot the buck and ASAP I went to the gunshop.
The worker inspected the rifle and candidly informed me that the culprit was some threadlocker dropped on the sear. Foor your information, the trigger was Jard, not locking the bolt.
 
Afternoon everyone, thank you for all the replies! Haven’t checked on here for a while so apologies for the late response. I showed it to a friend, who’d had similar issues before and is thankfully a lot more capable than me with these things, turns out one of the adjustment screws had loosened over the years as we moved it less than 1/4 of a turn and it was going off every time you closed the bolt. Backed it off a good way and locktited the screw so it shouldn’t happen again.
 
I have an idea in the back of my mind that there was an alleged issue with some Remmy 700’s having an issue, never proved that I am aware of..
A quick search and AI came back with this;

Remington 700 trigger issues primarily involve risks of unintentional discharge, particularly in pre-2006 "Walker" triggers and 2006–2014 X-Mark Pro (XMP) models. Defects include firing when switching off the safety or without pulling the trigger, often caused by poor sear engagement, dirt, or excessive factory sealant.
Key Remington 700 Trigger Problems
  • Unintentional Discharge: The most significant issue is the rifle firing without the trigger being pulled, often when the safety is moved to the "off" position.
  • X-Mark Pro (XMP) Recall: Models produced between May 1, 2006, and April 9, 2014, were recalled due to excessive sealant (bonding agent) in the mechanism, which can cause failure.
  • Walker Trigger Issues: Older models often face issues with the trigger connector becoming misaligned or contaminated, leading to accidental discharges.
  • Trigger Failure/Tacky Action: Due to tight tolerances, the trigger can become contaminated with dirt or, in cold weather, oil can become thick (tacky), causing the trigger to fail to release the sear (failure to fire).
  • Safety Failure: Some reports indicate that releasing the safety lever can trigger a misfire, a symptom often linked to poor maintenance or excessive modification.

Common Causes
  • Contamination: Rust, debris, or dried oil/grease inside the housing.
  • Excessive Adjustment: Too little sear engagement or a trigger weight set too low.
  • Manufacturing Defects: Excessive sealant (on XMP triggers) or poor tolerance management.
  • Replacement Issues: Some aftermarket triggers, if not adjusted correctly, can also lead to cocking or firing issues.

Remedies and Solutions
  • Check Recall Status: Verify the serial number on the Remington recall website.
  • Clean the Mechanism: Use aerosol gun cleaner/lighter fluid to flush the trigger assembly, followed by dry lubricant.
  • Adjust/Replace: If comfortable, adjust the sear engagement, or replace the trigger with a high-quality aftermarket option like Timney, Shilen, or Huber.

  • Professional Gunsmith: Have a qualified gunsmith inspect and clean the trigger to avoid potential firing issues.
I also seem to suffer from unintentional discharge these days
