I was shooting my .40 s&w this weekend with some hand loads that I assembled. Out of 100 rounds there were 3 that were duds all the others shot flawlessly. I was using remmington primers kept my work area clean and washed my hands before priming brass. Any suggestions ?

Are the primers set too deep? Could just be bad primers.

Could be bad primers I've never used Remington. How did the firing pin strike look on the primer if it was the same as the rest must be a bad primer. I have always used Winchester and have never had one that didn't go boom. Always a first though I guess.

Are you shooting a Taurus PT-100? If so, it could be a light strike due to the firing pin block not fully disengaging in SA if you press the trigger reallllly slowly.

Nine times out of nine this is due to NOT seating the primers deep enough.

Did you try and fire them again?

Did they go bang on the second or third attempt?

sometimes the primers get contaminated with the case lube(if you lube the cases).

Did they sit out before you started reloading? I know its best to keep in a bag or can and very dry place.

I was shooting a springfield xdm I know the primers were deep enough. I dont know what to deep is to be honest the firing pin mark looked the same as the rest. I clean the cases after I resize so lube is out of the question. I also fired them a few times each never went bang. I appreciate all the help.

I've used Remington primers exclusively for the last 30 years. Never had a problem with one.

IME, most of the time misfires are caused by seating to shallow and the primer not "bottoming out" in the pocket, or seating too hard and crushing the priming pellet in the cup. Do any of your unfired rounds have slightly crushed primers?

ive found remington primers to be unreliable. remington ammo in general is pretty aweful.

mileage may vary
