    Barrel is not blocked.
    Case is not blown in 2 parts but very close.
    This was factory reloaded ammo......coming out of the place in St. Helens ,Or most likely.

    He's shot hundreds of rnds of this without issue.
    Mag got nicked by a chunk of brass.
    The rest seems ok after clean up.

    Freedom Munitions? I have some of their Hush Puppy subsonic loads I bought years ago. Do I need to pull a bullet and check my cases?

    It comes loose in bags . In a box of 500.

    The place that is or was in St. Helens ...I'm ONLY guessing is where its from as they are only 30 minutes away. This ammo was bought at local gun shop and they have lots of it.
    Pallets.

    I'm going to look at his gun ,brass ,etc ..tues morning .

    Sent Him pics of this 2 step stuff but Have not heard back yet.

    I cant get my 556 to run with FRT trigger
    Its a Rock River Operator(that shouldnt make a difference)
    I have a FA bolt carrier
    tried 3.0 and 3.8 buffers'
    have a 8oz buffer
    what is the ideal buffer weight?
    I get one round fired and second round chambers and then i get a light strike
    I have gotten 2 9mm guns to run flawlessly and one 45
    the pistol ctgs are supposed to be iffy. They run fine for me but NOT the 556
    Any suggestions?

    Have you checked the timing and the buffer spring? Go to quarterbore.com under AR-15/M16 for the timing check. Pistol caliber doesn't need as much energy from the recoil spring to strip a round from the pistol mags as the rifle rounds need to strip from the longer feed lips of the rifle caliber mags. As I recall the operator is direct impingement. How well does the upper throw brass on (a) semi? The standard carbine buffer (2.9 oz with 3 steel weights inside) is too light for full auto. The 3.8 oz (H1 has two steel weights and one tungsten) buffer is about as light as would work with a 16"/14.5" upper. Full auto tends to need a little more gas than semi auto as the bolt group not only strips the round from the mag, but must also trip the auto sear also. I might step up to a 4.7 (H2 has one steel weight and two tungsten) if the upper has a barrel of less than 14.5". There could be several small issues that together make for function problems. 8.0 oz would be for that .45 blowback upper. Since the direct impingement spreads the recoil pulse over several milliseconds instead of the blowback that is all at once, and the DI only needs enough recoil energy for function after the high pressure phase is almost complete, instead of holding the bolt closed during the high pressure phase of the pistol caliber blowback system. So an 8.0 oz buffer would add too much mass to the DI system. That extra mass would need more gas volume in the DI system for fuction.

    If you read the post above you would know which buffer and I also asked about barrel length above.

    My Rock River is a 16" barrel. I am ordering the H1, H2 and h3 buffers today and see what that does.
    I never used the 8oz as I am sure it wouldnt fix anything.
    The H1 is 4oz and h2 is 4.6 and the H3 is 5.5
    It is a DIGS
    Thanks to Scott for all that information

    Iíve been running a 9mm SBR with a suppressor and tac-con trigger with great success. Bursts & mag dumps are easy.

    Tac Con and success are rarely used in the same sentence.
    But our own Concorde has posted an impressive video showing it is possible.
    I can usually shoot faster with my standard trigger than my Tac Con. :-(

    After many delays and weather craziness, I finally got a chance to try my FRT with not only my mods to the spring and trigger, but also play with different buffer weights.
    WOW. The change in trigger pull made an INCREDIBLE difference! While before I couldn't get it to run AT ALL with an H2, much less an H3, it now lets me get EASY singles AND, to ME at least, a bonus of a slower ROF!
    I post details with my latest vid on my channel.

    Great Video Jack007!!!

    Tell all of us how you did the mods Thanks!
    I see that you have the details under your video but not how to make the trigger heavier
    I got my ARs to run
