Tre(y)13 0 Posted October 29, 2010 Report Share Posted October 29, 2010 so i just finished my conversion..took it to the range and sent 115 yugo surplus through her (now named Miss Fire). everything worked out wonderfully..the gun shoots straight, just a tad bit high and looks mean when the end of the barrel starts smoking now heres my question: what are common reasons for a recent convert to misfire? i emptied a mag on the 25 yard range, loaded another 10 in, moved over to the 50 yd, chambered a round, pulled the trigger, misfire..chambered another one: same thing. chambered another one: same thing. so i detach mag, unchamber the round still inside and field strip it. nothing seemed out of place other than the main spring seemed a little "loose" on one side (sorry the uneducated lingo.) after checking everything, i reassembled, loaded the mag up and blasted away another 75 rds without a single problem. could that have been a single, isolated event never to happen again or is this a sign of a deeper issue? any (helpful) ideas are welcome Quote Link to post Share on other sites
imarangemaster 315 Posted October 29, 2010 Report Share Posted October 29, 2010 Were there dimples in the unfired primers from the firing pin hitting them when the hammer fell? If the there are deep dimples in the primers but the round did not go off, it is probably the surplus Yugo ammo. The yugo stuff is made by Ingmann, and is pretty good stuff. If there are no dimples in the primers, then probably for some reason the bolt failed to go completely into battery (action not quite closed). hard to say without being there to diagnose. Should have nothing to do with the mag. Quote Link to post Share on other sites
paprotective 362 Posted October 29, 2010 Report Share Posted October 29, 2010 I had some hard Tula ammo primers. if it happens again check the primer for a small indentation... Congrats and welcome aboard. Al Quote Link to post Share on other sites

Tre(y)13 0 Posted October 29, 2010 Author Report Share Posted October 29, 2010 awesome thank you for the responses! to answer the first reply: no, there were no markings of any kind. the ammo is all yugo but different years and some even have different colored primers. so long story short: its the ammo not the gun?

imarangemaster 315 Posted October 29, 2010 Report Share Posted October 29, 2010 If you installed a bullet guide, it may be touching the bolt and occasionally kep it from rotating into battery all the way. This is more common with home made bullet guides. If so, dry the bolt and the bullet guide, paint the bullet guide with a thin coat of white out and work the action. See if any white out transfers to the bolt. That means it is rubbing. Quote Link to post Share on other sites
Tre(y)13 0 Posted October 29, 2010 Author Report Share Posted October 29, 2010 well no bullet guide..yet..i ordered one from diznag and should be recieving it by next week. so back to the original question.: is there anything i should look for to prevent this from happening again?

imarangemaster 315 Posted October 30, 2010 Report Share Posted October 30, 2010 If the carrier does not travel all the way forward, there is a "tail" that sticks out that will prevent the hammer from striking the firing pin if fired with it out of battery. About 1/4" of a gap between carrier and front trunnion is all that is needed to prevent the hammer from contacting the firing pin. Often the hammer striking the tail will cause it to travel that lasy 1/4 so you do not realize that it was not in battery at the time it was fired. Take yur top cover off, cock the UNLOADED weapon, and stop the carrier 1/2 to 1/4 inch from the full forward position. Pull the trigger and you will see what I mean.
