    I just fired my first 100 rounds in my Steyr M40-A1, I had one FTE and one FTF although there is a clear strike on the primer.

    I used a readily available ARMSCOR 180gr. FMJ. It's a good ammo company here in the Philippines.

    However, I would like to ask if anyone experienced bent casings. My shells were mostly d-shaped after firing. And also the occasional shell-in-the-face action. 90% of my shells were deformed. Any insight?

    i do have some pics but I don't know how to post it.

    dent in the casing? had it happen on first 200 rounds after that it diminished significantly.

    clean the gun before you took it out? FTF Failure to Fire? if failure to fire was it towards the end of the range session? could be dirty striker channel. too much oil can bring it up. could be the oddball bad primer. occasional for some reason the flashhole does not get made in the casing.

    pics find a webserver or photo hosting site on the internet upload the pics then get the address of the pics and link them in using the Img button

    Were you shooting at a covered outdoor range. Maybe a cooragated tin roof???? These look like they might have been bouncing off the covering..
    ............ :?: My friend was shooting his 1911 under one of our roofs and couldn't figure out why his brass was denting just like yours.....He was trying all kinds of machining when I told him mine dent just like that when it bounces off the tin roof........ 8-O

    no sir, I was on an outdoor range, I could not catch the scuff marks on the photos but these cases had horizontal scuff marks on the bent part. There are also some brass markings on the slide like the shells were hitting it.

    thats nothing to be concerned about I have had way worse dents.

    casings like the ones in your pics I have sized them and reloaded them.

    now if its lower and sharp crease dent I toss it.

    sizing and belling will usually do the trick sometimes a dowel can be helpfull. seating new bullet will remove dents also.

    I just shot my m40-a1 hours ago. I had one FTE and one FTF but the primer was fully dented. I would say that this is a defective primer. About the FTE, I'm not sure if my thumb touched the slide during firing that caused the FTE. I fired about 70 rounds of my reloads consisting of 180 gr. by precision bullets. This reloads are full power that I usually use on my Para P16 and they are accurate. Recoil is surprisingly milder than with my para. I also shot 50 rounds of 180 gr. jacketed hollow pt. Winchester factory ammo. Overall with Wincheste was poor. Accuracy with my reload was average. Sight alignment was very easy. One thing I noticed though was I had a little difficulty adjusting whether to shoot dead on or six o'clock because of inconsistent target hits. It could be either me or the barrel or ammo not sure yet. I stopped shooting because my thumb was already sore in loading the ammo to the mags. My overall first impression was mixed. I think I should give my self more time to get used to my M40-A1. This is my first polymer gun afterall.

    Nixon, you are surely right sore thumbs are my problems too :lol:

    Neviv, my kabayan, how many rounds have you gone through? I suspect that it will need about a couple of hundred rounds more of FMJ if it needs to be broken in.

    And to the Steyr Guru, Mr. Apathy...thanks for the advice. I was ready to throw those casings away, thinking that they are'nt fit to be reloaded. :idea:
