    Soft primer strike problem is rearing its head


    During the first and second firings of my Savage Axis HB in .223, I had probably a total of 7 soft primer hits.

    I read the thread on soft primer strikes and their treatment, but can't really recall what was done - IIRC some of the respondents said that they took the bolt apart and reseated the springs and modified some washers, is that correct?

    I'd rather not send the rifle to Savage for repair - it's a colossal PITA to do this. What did you do to fix yours?

    Doing some research made me recall what rounds were failing... I am sure they were my handloads, with CCI primers. These handloads were made with Lee Full-Length Sizing Dies. I wonder if the full-length resizing I did set the shoulders back a little too far and I have a slightly more generous headspace in my chamber in the Savage? Could be the round is "scooting ahead" in the chamber under the impact of the firing pin.

    I will also measure my firing pin protrusion and report that back here. I am using a Lyman Case Length Gauge to evaluate the re-sizing of my rounds.

    Keep in mind I reload those for the ARs, never having intended on using them in the bolt gun... I have 60 shells once-fired in the Axis... I will neck size these and shoot them to see if they all fire with the CCI primers. If so, I may have my answer.

    Which CCI primers? My Axis will also have light strikes if I shoot 5.56 rounds that have hard primers, but I never have issues with factory .223 rounds....or my handloads with CCI 400's in them. And are your primers seated fully into the brass? And before anyone says anything my Axis has a Wylde chambered barrel so I can safely load both...

    I have never had a light primer strike before. I shoot nothing but my own reloads. With the current panic buying I bought 1000 CCI primers and today I had 3 misfires with what looked like light strikes. I do know that CCI primers are harder and may be designed for AR 15 with its floting fireing pin. Some of the Federal #6 primers will cause Slam Fires in the AR.

    You have two paths. Pic one and follow it.
    Measure your shoulder length and confirm it is correct. Dry fire with primed brass to test.
    Rebuild your bolt to look for issues. Dry fire with primed brass to test.

    After around 200 hand loads thru my 243 Axis I started experiencing light primer strikes. I tried polishing the FP and the inside of the bolt w/o it doing any good. I had my LGS order new springs from Savage and the problem went away.

    Don't blame it on the firing pin spring till you can prove it!!
    Still got some of those FTF rounds??
    Increase the OAL by pulling the bullets out to a "jam into the lands". Chamber them, pull the trigger and see if they will BANG.
    First thing I look for in RELOADS is if the shoulder got pushed back too far. If so, the case gets pushed forward in the chamber by the firing pin and you end up with a FTF. Looks like a soft strike.
    Long OAL keeps the case head against the bolt head so the primer will go off.
    And I'll add, I shoot nothing but CCI BR and Mil Spec primers. Only primers that EVER FTF were in cases that had the shoulder pushed back too far. Had one round that got wet from laying out overnight, it just went fizzled.
    Been there, done that. We learn as we go.

    I was routinely neck sizing for my Axis 243 and still experienced the light primer strike that's why I finally ordered the springs. Changed the springs, continued to neck size and had no further light primer strikes. When the new springs arrived I compared them to the old ones and the new were overall longer. Jamming bullets in my case wouldn't have mattered. For someone else, it just may do the trick.

    Curious if either of you actually tried increasing the round OAL to see if that cured the problem or just popped for a new spring?
    I don't shoot an Axis so maybe there's a difference between the 10,110,12,112 etc. or the Axis?
    And thinking back, the few FTF that I experienced happened on my XP 100 converted rifle in .221 Fireball. Case OAL cured that issue and it has never happened again.

    Yep. Finally ran out of options except another spring.

    If you used 41 cci primers then that is your problem. Not only are they thicker the anvil is spaced out farther to prevent slam fires. Regular 450 mag cci primers are the same thing as 41 but the anvil is in the standard location as the 400 primers. 400 primers are not meant to be loaded in 223 or 556 ammo as it is thinner and was designed for 22 hornet class of cartridges.

    What your saying is very true for Small Rifle Primers but in FOGeologists' case and mine with our 243s, LRPs were involved.

    LR military primers are made the same way the sr 41 primers are. The anvil is spaced out farther to prevent slam fires. Another way to overcome this is run a firing pin protrusion out farther.

    More than likely the head space was on the long side. After having the new springs in your bolt now I can guarantee the spring is a lot shorter now than when you put it in.

    Guarantee? Im not sure I agree with this unless we heat them up enough to anneal them or the material and the heat treat process were flawed.

    Well I wanted to give him a chance to clarify it before I went that far. I digress, yours may have been the right approach.
