Shotgun misfires

edited March 2009 in Perry Shooter Competition Shooting and Reloading Forum
Went to the sporting clays range yesterday & had some misfines with my reloads. Only happened with AA HS hulls. It would give a poof & through the shot & wad out of the barrel. A couple of times the wad stayed part way down the barrel. When the wad would stick there would be some unburned powder present. I'm using win 209 primers & longshot powder. One of the guys with me thought that maybe the powder charge didn"t drop, but the presents of powder would dispel that. The one thing I did notice was the wads that didn't clear the barrel were claybuster non HS wads. They crimped fine but did they maybe not seat against the powder & leave some air space? Any thoughts?

    Normaly that's a sign of no/not enough powder. Before the powder burns completly, it has to reach "normal" operating pressure, so even a partial charge will give you some residue.

    I see this quite often .
    We have 3 shooters at our club who continually have this problem .
    All 3 use Dillon loaders .
    Powder not dropping right .
    What loader do you use ?

    Short powder charge is main culprit from progressive loaders. Could the cases be damp from being left on ground or given to you by someone else ?? Drying with hair dryer or direct sunshine will do it. Bob

    Don't know which gage you're shooting but I'd guess it be 12 or 20 if you're shooting sporting clays. Longshot powder is intended for heavy shot charges but has an application for targets with standard payloads in 12,20, & 28. You'll notice in the charts that it is not used with any payload lighter than 1 1/8oz in the 12. If you're trying to use it with any load lighter this might account for your erratic burn results. Also, being on the edge of the envelope with a 1 1/8oz load cold weather may be a factor.

    I've had this happen and it was a lack of powder dropping through my MEC progressive (as most stated above), only happen during the winter months, turned out to be static holding the charge.

    I just slow down and tap the tube during the winter and this seems to have eliminated the issue, however, a good friend with the same issue actually attaches a static strip to the powder cap and lays the strip inside the powder, claims it works.

    Good luck

    Sorry it takes me a while to reply, don't have a computer at home & been busy at work. It is a Mec progressive loader and 28 gauge. Shells have not been on the ground. Would a powder baffel help this?

    powder baffle might help. also did you posibly get moister in your powder and is it clumping up? if its clumping up it will cause that as not enough powder will drop from blocked bushings.

    I load the Win AA Hulls (silver) in 12ga with the Claybuster wads WAA12SL in a MEC JR and haven't had a problem with them. I do use the REM209P primer and Titegroup powder though.

    I've accidently loaded a 16 ga in my 12 ga and it struck the primer and god saved my life. I had to shove a metal rod down the barrel to get it unjammed.

    The progressive MEC is short cycling the charge bar. It is not moving all the way across the powder bottle so it does not get a full charge of powder on every stroke. Visually check that it travels all the way left and right. Weigh a series of charges. They should be within .2 or .3 grains of each other. The baffle is supposed to keep the powder charge from becoming too heavy from the weight of a full bottle of powder. It shouldn't cause a light charge. Make sure the rods are adjusted properly for a full cycle each time. Bob

    A weak crimp can also cause this, even with a full powder charge. If the crimp opens too soon, it allows the shot and wad to move. That increases the volume in the powder "compartment" enough to slow or even stop combustion. Result: the dreaded BLOOP load. If these hulls have been reloaded several times, consider them worn out and discard them.
    I may be a bit crazy - but I didn't drive myself.

    They were once fired hulls. I loaded some for my friend using everything the same other than the wad. He never had any problems.
