syborg Posted February 12, 2013 Report Share Posted February 12, 2013 Hi folks. I've just picked up an old belgiun .410 and I've shot a few gamebore 2" cartridges through it and ive noticed the ends of the cartridges are burnt and look melted.. The chamber depth of the gun measures up just a knats chuff short of 3" using a depth gauge. Could this be caused my using too shorter ammo or a very worn gun barrel? Regards Syborg.

Guest cookoff013 Posted February 12, 2013 Report Share Posted February 12, 2013 no, usually its due to slow burning powder not reaching clean burn in the first instance, and could be smouldering on the way through the barrel, this can toast the crimps, but it could just be the load, or the hull life is seriously spent. are they homeloads? it doesnt sound like an issue to me, i`ve toasted many a hull.

syborg Posted February 12, 2013 Author Report Share Posted February 12, 2013 I was given a box of 410 cartridges with the gun and these looked mint. I think they were Only about 3 months old but I could be wrong. Out of 25 so far 19 have roasted ends. Maybe damp cartridges! I,ll be buyin more ammo soon so I.ll see. The fun I used is very old and the barrel has definatley seen better days so thought it might be that. Thought it may of been bored Out from a room gun because the the chambering is stepped in two places. First step is about 2" and next major step is 3".. Baring in mind this old gun must be 60-70 yes old at a guess.. Regards Syborg That should of read "rook gun" not room gun lol Quote Link to comment Share on other sites More sharing options...
Blunderbust Posted February 12, 2013 Report Share Posted February 12, 2013 (edited) Is your gun a hammer gun? My reason for asking is, that if this is the case it may be that new firing pins have been fitted and they are a bit long. They might be piercing the primers. This is noticable in non hammer guns buy the fact that when you close them there is a chance thet they will go off due to the pins protruding through tthe breech face. With hammer guns it is not going to happen until the hammer strikes the pin and forces it through the primer. I had the exact same problem on my Hamer 12 guage which was cured buy the gunsmith filling the firing pins down a bit.

syborg Posted February 12, 2013 Author Report Share Posted February 12, 2013 Hi blunderbust, I've had a good look at the primers and there is no sign of puncture, the pin Mark is slightly deeper than my 12g but it could be an illusion as the carts are smaller, I,ll try new ammo first as apparently those particular cartridges had been stored in a garage over this winter..
