Winchester primer failure

[Harvey Mushman]

I'm fairly new to reloading. Over a thousand rounds with no problems. I have been trying different brands of primers and today I had my first misfires. Out of 10 rounds 5 were misfires. So I stopped using that batch. They were Winchester primers with 50 grains of RL-15. The first 100 primers from this 1000 were fine. Trying to think If I could have contaminated them somehow but I careful while handling. Cases were neck sized with no lube. Does this happen once in a while? Any ideas???

This may not apply since related to Winchester bulk ammo at WW (9mm).

I have had lots of lite strikes w/ this ammo. I had a competion hammer spring, went back to stock because of it. Others told me that the Winchester primers take more force to fire than say - Federal.... Two competition shooters told me the same thing....

But - the difference is big. I shot almost 2000 Federal, and reloads with no issues.

Started using Winchester 9mm, and was getting 1-2 lite stikes per box of 50.

BUT, every one DID ignite on second firing of pistol, (let it timeout for hangfire, and then shot again).

Hope that helps.

Some primers can be harder .??? I have gotten away from light springs.

That is not that common - how were they stored - could they have gotten damp, too hot? Did you touch the anvil side with your fingers during the loading process.

Never had a problem with Winchester primers. Only primers that have given me problems were Federal since the XL-650 does not like them. A common problem in reloading is the primers not being seated all the way in the primer pocket. What happens is the first strike seats the primer all the way so that the anvil
is in contact with the bottom of the primer pocket, second strike primer does it job and goes boom. So take your time and make sure that your primers are fully seated.

^^^ THIS is the most likely problem with your Winchester primers.

haven't yet had a problem with Win primers. CCI occasionally gives us primers with nothing in them, lol. good thing it's noticeable and usually doesn't actually make it into loaded stuff.

The few times I've ever had trouble with primers is ^^^ this.
