Winchester Small Primer Not Red

They look red to me

My eyes are seeing red also!

 

A few years ago Dan Bedell ran into a lot# of SPP that went bang but gave about 30 power factor lower.

They had a Black cast to the priming mixture.

BUT

That was back when primers were scarce and he got them from another shooter and they were a couple years old when he got them etc etc.

 

Should probably load up a test batch with each and chrono them to see if they run the same

This sparked mu interest, so I went to the basement and loaded some tubes. I found one "not so red" primer in three tubes I loaded. Odd, but it seems that red stuff is some sealant material and in the case where it is less red, it looks like the top has flaked off.

I took two pictures, the primer in question is the second from the left on the lowest row.

Unless the primers are being exposed to extreme conditions a little flaking of the primer sealant won't cause light strikes. Are the primers being seated properly? If so then you probably have a gun problem.

I ran into the same Odd looking Winchester SPP primers. I loaded 800 rounds last week and found 2-3 primers per 100 out on 1 box of a thousand. These look just like the pictures with a significant reduced amount of sealant on them. I segregated them while loading; loaded them up and they all went bang like the rest of them.

A little late on this one but I had the same ratio of not so red in my last case of Winchester spp. In case you're still wondering, they all went bang for me.

I have probably loaded at least 400,000 WSP primers with no issues but last season, shooting a classifier, had one shell not go bang.  Retrieved the round, pulled the bullet and knocked out the primer.  No explosive and no red in the primer.   I use a Dillon primer tube filler so rarely check the primers.  1 in 400,000 isn't bad.
