Thread: White River Primers - Any misfire issues?

I loaded up 20 odd rounds of 284win 140BTs with RE16 filling the case (slight crunch) and only difference to normal was White River primers vs FED210s as was running low. Tikka rifle/anction and never any issues before. Cases full length sized.

Didn’t have much time as was just checking zero vs my normal load with 162s

2 out of 5 didn’t go off. Primer was hit. This was confidence killing as I can’t hunt with a load I don’t know if it will ignite.

Has anyone else experienced this with WRE primers?

I’ve used them and haven’t had any misfires. Haven’t seen anything on the net suggesting anything untoward other than they are abit thicker and can be difficult to seat in some brass.

Measure primer height. Measure primer pocket depth. Seat primer to ensure the anvil is bottomed-out on the base of the pocket.

WRE are known to be a little bigger in diameter than most, so are a snug fit in the primer pocket. So make sure they’re seated sufficiently deep

Had nothing but brilliant results over 500 rounds now over various cartridges both lrp and srp

In my experience, they are a little bigger in -height- and can be difficult to fully seat. Have not had a single of at least the 300 I've shot that failed to go off first strike.

They seated well - I knew they were a bit bigger so gave a few cases an extra tweak in the press. I checked them all at the end and made sure they were just below the rim. I actually liked the firmness. Anyway - I’m not blaming them, and had also checked internet with nothing but good reviews. It just plays with your mind. I might wind back the sizing die a touch to try and get more shoulder contact and resist the firing pin strike. Thanks for replies.

Maybe also relax your firei g pin spring between uses too.it helped no end with my 223 when I first got it.had heaps of misfires till learnt to do it. With bolt out turn end so the sear?? Bit slides forward and end of bolt rotates.takes a bit of welly to turn it back again,one of my four I need mechanical assistance,the others turn no drama. The stiff one gets padded vice grips to hold end and turns easy with added leverage. Might help.wont hurt.

The problem is probably light strikes dismantle and clean the bolt.

Would be closing on 400 shots now with White River primers. Not one failed to fire.

If you still have fired cases with the old primers in or some of the spent primers you can measure the indent of the firing pin in the primer cup and compare the two. Also, measure the height of the anvil and the depression of the impact mark and compare those...

Sometimes there's another reason for the misfires or failure to fires - one case of this it wasn't until the rounds that failed were disassembled that we worked out the reason for it. Somehow, the handful that failed to ignite had been assembled using primers that were missing the anvil. A lot of blame on the rifle, the powder, the dies etc etc but a simple check on the components at the step of priming cases would have identified the issue and that misfortune would have been avoided! Not saying that's the issue with these primers failed to ignite but there will be a reason for it and it's just a case of working through until you've found it. Once you've found it, then you can correct it.

Check the headspace/shoulder lenght of the fired cases vs the ones that failed to fire....you may be oversizing your brass

If your not confident taking bolt apart a good spray out with brakeclean might do it

hope they are good !! have back ordered 5k!

Pull the other 15 and see if they go bang in rifle...primer only.

Use a quality primer pocket uniformer. K&M 3in1 is the tops.
