    I went to the range today with the wife...

    We brought the AR with the
    - Spikes Tactical .223/5.56 upper
    ~ and ~
    - Rock River Arms .458 Socom upper.

    After getting everything setup, (spotting scope, target, sand bags and
    scope) I was finally ready to send my first .458 Socom down range to
    the 25 yard target to get the 4x scope sighted in.

    After very careful aiming i slowly squeezed the trigger... click... now if I
    could just squeeze a little more the round is about to go off... wait! did I
    already hear click!? Great... miss-fire... probably my fault, so I cycled in
    another .458 and gave it another pull... CLICK AGAIN!!!

    So it goes on like that for a while. I eventually had the range master come
    over and explain how my bolt and firing pin needed to be cleaned before
    coming to the range. How the parts were very sticky and gritty.

    CLEAN WHAT! Why? this was new in box when I came to the range.
    Why do I need to clean it? well... I did find it crazy as to how much black
    grease was on the parts with it having never been fired before.

    So I put the Spike's back atop the Spike's lower and we finished sighting in
    the irons at 100 yards. It gets me that my NEW upper didn't work at all.

    I got home and took out both bolts and firing pins... Can anyone spot any
    differences??? Keep in mind not a single shot fired on the RRA, why so
    dirty?

    No big-bore holes to report, just little ones:
    Started at 25 yds to get the sights together.

    At 100 yards, had to adjust the sights down about 6"

    Nice shooting. Now clean that bolt from the .458 and go back out to the range.

    .Curious to see if a good cleaning does the trick or if there is another issue

    you really shoulda cleaned both guns well especially the bores before shooting. rra packs theirs in preservative heavy lube so it doesnt rust while waiting for a new owner most companies do the same.

    trying to fire a new gun with out cleaning the bore first can damage your firearm.

    Alright...
    I finished scrubbing the crap out of these uppers inside and out. Each part
    down to the bone. Lubed them, then I ran out of daylight. So I moved to the garage. I wanted to see if the .458 it was seating the round correctly.
    So I loaded one round into the magazine and released the bolt.

    Round slid right in. Seemed to seat correctly but when i went to eject it.
    the bolt wouldn't move at all!!! What! I got a live freakin' round chambered
    and can't get it out. After lots of wiggling and tugging finally got it loose.
    WHAT WAS THAT ABOUT?

    Maybe I put it together wrong... but it doesn't look like there's a lot of
    ways to mess up putting the bolt together.

    So before I did that again, I removed the firing pin. Manually dropped the
    round in and closed the bolt. AGAIN it stuck! and wouldn't go anywhere...
    So i finally got it to eject and I then work the hell out of the bolt, now it no
    longer feels like the rails are made out of sandpaper and the bolt puts the
    round in and ejects it effortlessly.

    I'm not sure what the problem was other than parts that weren't broken in
    yet. I still don't get how the round wasn't hit by the firing pin when the
    hammer went click.

    SO FRUSTRATING.

    Kimber 1911 - came pre-fired
    Mossberg 500 - came pre-fired
    Glock 17 - came with 3 shells proving it works

    Spike's Tactical AR-15 - don't remember it saying it was pre-fired but it did work right out of the box no problems.

    Rock River Arms .458 - !!! I'll let you know if it works next time I can
    make it to the range. :mad:

    Did you make the rounds yourself or buy off the shelf ?? Sounds to me like incorrect headspace. If your rolling your own its not an easy round to load. The redding dies are best but dont seat and crimp on the same stroke it will change the headspace or destroy the case leaving a nearly impossible to remove case in the die.

    Store bought... er from the internet.

    it might be a headspace issue. It might be shallow primer (but i don't think so)

    The guy who sold it to me is taking it back and is going to make sure it works on my lower. I'll have to drop it off later this week.

    Ive got around 50 i screwed up witth incorrect headspacing that do exactly what you describe. Ive also got a rra 458 socom. Once i got the die set right no issues. Ive gor a headspace case gage for the socom now and those bad rounds are indeed out of spec.

    The Cor Bon should be good to go, also keep in mind that SBR also makes 458SOCOM ammo - Tracer Ammunition. I would suggest ordering a case gauge from SBR and checking the Cor Bon ammo. It will also be useful if you decide to reload your own 458 artillery.

    It sounds like your chamber may be a hair tight.

    Just finished ordering 2 boxes of SBR.
    I'm trying to figure 1 type of ammo and sight my scope to it.
    If the Cor Bon doesn't fire at all, guess I'll have to use SBR.

    Cor-Bon is 405 gr JSP
    SBR is 410 gr JSP

    Not sure how much of a difference each would make at 100 yds.

    GAWD I wish my upper was in working order.

    Let's try to put huge .45 cal rounds in my gun that was designed for a .223... "What could go wrong!?" Well... I found out...

    There were too many pictures for me to post in this thread as this forum
    only allows so many pics per post.

    I markered up a round to see where it was sticking:

    *** This is what I found ***


    The conclusion I come to is SHOCKING!!! actually, probably not.

    I still need help with what it's sticking on and deciding on who's to
    blame in this sticking mess.
