mickyh Posted February 4, 2018 Report Share Posted February 4, 2018 Anyone ever done it? I just have by accident obviously, dropped my handwarmer into pocketfull of cartridges. A petrol fueled handwarmer, other types are available. Realised after 5 minutes, but it happened. Is it like a mobile phone in a filling station ? Never going to cause a fire ever. Or am I lucky still to have two balls! Anyone else care to admit to any stupid stuff ? Quote Link to comment Share on other sites More sharing options...
johnnytheboy Posted February 4, 2018 Report Share Posted February 4, 2018 I’ve done it hundreds of times and never thought of any danger ? Quote Link to comment Share on other sites More sharing options...
Dougy Posted February 4, 2018 Report Share Posted February 4, 2018 I wouldn't do it personally, But by all means someone try it and please feed back how long the recovery time is. Quote Link to comment Share on other sites More sharing options...
getthegat Posted February 4, 2018 Report Share Posted February 4, 2018 Could work. I guess the question that needs answering is, how hot can a cartridge get before it's dangerous. Answers on a post card...... Quote Link to comment Share on other sites More sharing options...
Mr gen Posted February 4, 2018 Report Share Posted February 4, 2018 I have done it aslwell and had a moment of panic but thinking about it rationally, although they do generate a lot of heat, it shouldn’t be enough to set a primer off or melt the cartridge plastic Quote Link to comment Share on other sites More sharing options...
Benthejockey Posted February 4, 2018 Report Share Posted February 4, 2018 People put cartridges albeit in boxes on top of radiators which unless they’re our naff radiators get too hot to hold your hand on, and they don’t go pop. Although probably in advisable you’re probably very unlikely to become a eunuch. Probably. Quote Link to comment Share on other sites More sharing options...
panoma1 Posted February 4, 2018 Report Share Posted February 4, 2018 (edited) When I was a kid someone threw a couple of cartridges on a bonfire, the embers were red hot, but the cartridge took many seconds of searing heat before it just went Pfut! I cannot imagine the heat from a handwarmer would reach a prolonged temperature anywhere near that required to set a cartridge off? But I would ere on the safety side! And not keep em in the same pocket! Edited February 4, 2018 by panoma1 Quote Link to comment Share on other sites More sharing options...
walshie Posted February 4, 2018 Report Share Posted February 4, 2018 If it's not hot enough to set fire to your pocket, it's not hot enough to set a cartridge off. Quote Link to comment Share on other sites More sharing options...

Guest stevo Posted February 4, 2018 Report Share Posted February 4, 2018 What a bunch of drama queens .... if your hand warmer got hot enough to set a cartridge off , it would be to hot to touch haha ? cartridges will not not go off unless in a chamber . Throw one in a fire , your get nothing more than a pop fro the primer . Quote Link to comment Share on other sites More sharing options...
mickyh Posted February 4, 2018 Author Report Share Posted February 4, 2018 Not quite true. I Shot one with an Air Rifle when I was 14. From about 10 yards away. 1 1/16 Eley -BSA Meteor Big bang and the shot whent everywhere, not sure how much power it had though. Dont know how I still have all of my fingers doing daft stuff as a youngster! Quote Link to comment Share on other sites More sharing options...

Aerosol cans on a fire are more dramatic than ammo, especially expanding foam aerosols! Quote Link to comment Share on other sites More sharing options...
mickyh Posted February 4, 2018 Author Report Share Posted February 4, 2018 Yes I shot at the primer. I was refering to the chap who said "Just a pop from the primer" It didnt burst the cartridge, just opened the crimp. Looked pretty violent though!

A shorting 9v battery gets hotter than a handwarmer so maybe. Try it and see. Had a 9v battery in my pocket and I guess my keys or coins shorted it, took a mo to figure out why my pocket felt it was in fire. Takes a while to heat up by the way, it isn't instant.

Hamster Posted February 5, 2018 Report Share Posted February 5, 2018 As a kid I have shot the primer in live shotgun cartridge loads of times and whilst it is true to say that proper combustion does not take place outside of a purpose designed chamber, don't assume that they all just go pffut either. I once place one inside the small hollow of a tree and literally had to duck down as the rocket effect sent the shell zooming over my head at a good rate, if memory serves the range was around 20 yards. Another time when all efforts in hitting the centre failed on one particular shell, I gave my .177 Whaley Crossman 2 pumps and gently lowered and centred it on the shell which was lying flat on the ground in front of me, why or how it managed to propel itself forward and head butt the bone at the side of my foot I know not but I can promise you it was more than a pffut. PS. I doubt you can make a shell go off with radiator or handwarmer heat if your life depended on it. Quote Link to comment Share on other sites More sharing options...
Scully Posted February 5, 2018 Report Share Posted February 5, 2018 We’re talking about what happens to a cartridge if it is heated up, NOT about detonation, and I can assure you that if you throw cartridges in a fire they just go pphhhffft!

Yes I know that, I am merely adding to the general discussion (as others have done) that in certain circumstances even outside of a chamber they can do more than just fizz out.
