Reloading AR-15 Ammo
« on: April 29, 2014, 11:53:24 am »
I recently reloaded  a bunch of AR-15 ammo, I used IMR-4064 with a Sierra 55gr SPBT boat bullet, I used the 5.56 dies. The first shell out of the clip jams. When I use a factory load first and then the reloads to follow they cycle fine? Why wont the reloads cycle first out of the clip???

    You're supposed to remove the clip and spoon from the magazine before loading it into the rifle.

    Ok, so seriously, need better description of the nature of the "jam." Pictures help.

    Do you mean that it's not chambering completely?  Is it the round still stay in the magazine?  Pictures would be best.

    Maybe check your Over All Length and see how it compares to your Factory ammo.

    ^ This.  Is that first handloaded round not chambering at all or is it not ejecting after firing?

    Begin with the rifle bolt down on an empty chamber and no magazine in place.   Load the full magazine into the magwell and hit it on the bottom to lock it in place.  Then rack the bold back and release.   Does it chamber the round, or is it failing to strip it from the magazine?  If it strips it from the magazine, does it chamber, or is the bolt only partially closed?

    Or, if it closes, locks and can be fired, then what happens when it tries to extract the case?  Is the case sticking in the chamber, or is it pulled from the chamber but not being ejected and hanging up inside the upper receiver as the bolt moves back?

    Detail please.  And, yes, a photo would be helpful.

    Are you using a full length or neck only resizing die?  Neck resizing is reserved for bolt action rifles but if you neck sized only for a semi auto then you will have chambering problems.  Now to go a step further, you might want to invest in a small base resizing die.  They are made specifically for semi auto actions by sizing the brass slightly under SAAMI spec to ensure 100% feeding.  I use a small base die and I've not had a single problem.

    The first round strips out of the clip fine but does not chamber completely ? I'm full length sizing the cases with 5.56 dies. The only thing I can see that matbe hitting on the case is the lead tip on the bullet. The bullets are seated to the correct COL, should the bullet be seated deeper because they are lead tipped?

    You don't want to seat the bullet deeper than what's recommended as that will raise the chamber pressure.  Make sure that your full length sizer die is set up correctly (the shell holder should be contacting the bottom of the die) and if that doesn't help then get a small base resizing die as it pushes the shoulder back slightly and that should fix the issue.

    Pictures, man! PICTURES. Is it failing to feed, not going fully into battery, bullet getting caught on the feed ramps? Do you have the same problem if the first round is on the other side of the magazine? Have you tried different magazines?

    I agree with post above that you should not go deeper than specified COL.  But, this can be confusing because different manuals have different COL listed.  It's just what the manual used for testing pressure. 

    What manual are you using and is your load anywhere close to max?  What is the COL you are using?   I think the shortest I've seen in the manuals I use for 55 grain bullets is 2.220" which is what I'm using for Hornady 55 grain FMJ plinking ammo in LC cases over 25.5 grains of H-4895.  This is well short of max magazine length, but does ensure reliable feeding (100%).

    Some on-line manuals are showing 55 grain bullets seated as short as 2.200", but I don't know what charge weight of 4064 you are using, so I can't comment on pressures, and every rifle is a world unto itself when it comes to handloading.
