Factory Seconds White River Energetics LRM Primers

[JakeWes]

I recently purchased 5000 LRM factory seconds primers from American Reloading since they were cheap. The description was vague, only stating that they were magnum primers and that they had a 0.1% chance of not firing and to not use in cold weather. Upon further research, they are from the new White River Energetics company here in the US.
Initial observations, they all seem to be uniform but the only thing off about them is that they are a little too tall. In most of my brass they sit just at flush. Other than that, they work.
To test the reliability in cold weather, I loaded 10 rounds of 7mm STW with 85.0gr of WC872 and a 160gr Speer.
Big case:
Slow burning powder:
Temperature: 33°

All rounds fired just fine, with the same accuracy I get with normal WLR primers and this powder.

I forgot the proper rear bag attachment for my rest, so my setup looks awkward.

Never seen factory seconds primers… not a terrible price either.

Website says 0.01% which is 1 in 10,000 that won't work. Seems like a good deal if you're a trusting man but something about 2nd Primers is a little questionable. Then again, I have a brick of CCI250s that wouldn't reliably go off immediately a while back and those were purchased retail at the time.

 

[Model19Man]

Not sure if I would but glad it worked out for you.

If I didn't already have a good supply of primers I'd jump on that. I've used the regular WR large rifle primers and they were no different than CCI IMO.

That would be 1 in 1000.... .001is 10,000 I do believe

If this gets around and people start buying from them, we might start to see retail prices begin to go down! Most of their powders are out of stock but if they had something similar to H4895, I'd be tempted to try it!

.01% = .0001 =>the % moves decimal left 2 places. .01% of 5000 (a case of primers) is 0.5 therefor for every two cases, theoretically one primer will malfunction. That is of course assuming they meant to put .01% and not .01 (1%) chance.

I bought 5K of the LR primers and have been working up loads for 308 Win. So far they are consistent and I have had no problems.

I bought 5000 of the White River Energetics large rifle primers and so far I am getting comparable results to the Federal 210's. The White river primers do stand taller, as compared to the federal. The White River are .132" tall including the anvil and the federals are .126" tall with the anvil. The cup on the White River is .123 and the cup on the Federals is .116. (with my rudimentary measuring skills) The anvil on the White River does not compress as easily as the Federal, as I like to keep the anvil compression as consistent as I can. I'm going to uniform some primer pockets to see if that will square up the corner in the bottom of the primer pocket. My thought is that the cup is coming in contact with the rounded edge at the bottom of the primer pocket not allowing a consistent crush on the anvil. Overall I am pleased with the White River primers but would like to have more consistency seating them.

I'm not sure if it was the brass, how many times it was fired or #3, but some have had seating issues (including pistol primers) with this brand. I've only used cci's, so I can't say much? However. I do want to try some along with a few other brands. In the last 2 years I've bought federal, Winchester and Remington to try. Now to try s/b, wr and magtech in firearms that aren't as important or need to be as precise.
