.338 Lapua Primer Question

[BrkdkJarhead]

Ok it's my first post and I get to start out as a dumbass.
Yesterday I loaded 80 rounds Here is what I used:
Lapua Brass
Barnes 265gn LRX
IMR 7828 ssc from 78gn to 82gn
primer I screwed the pooch and didn't notice that I had WLR instead of WRLM or Fed 215m in the hand primer. Now they are all loaded with WLR primers.
I really do not want to dissasemble all these rounds and I realize that performance of the rounds will not be what it should be. What I am thinking of is taking them down to the 100yd range and shooting them up.
Does anyone see any dangers to the gun or shooter doing this?
Thanks

Re: .338 Lapua Primer Question

I can't comment on the powder or charge, and if it sounds safe, but having used non-magnum primers poses no risk other than higher risk of a hang fire or dud...

...highly doubt you'll experience either of those...

If you do, follow proper safety protocol - give it time, don't open the bolt until you're certain it's not going to fire, meanwhile keeping it pointed in a safe/good direction.

If you just want to blast some ammo through your rifle, that's fine, but personally, I wouldn't fire 80 rounds through my 338 "just because"...not at $0.50+ per round in barrel wear.

I ran fed 210s in a 338 lapua improved with 97/98 grains of RL25 for years without issues. Have not used 7828 so don't really know if there will be an issue but I completely agree with Turbo 54s comments and that pulling them down will at worst take some time and will then give you confidence in you work.
I have since started using 215s

Thanks, it was bugging me that I messed up and I have never encountered this particular problem before.

Re: .338 Lapua Primer Question

Catching a mistake before it becomes a problem is far more important that making mistakes. Everybody makes mistakes but not everybody catches them before they become problems.

I doubt your mistake would have been an issue but good for you for catching it.

Better to pull them down and use the primer you intended to use in the first place. Regular vs magnum primers will make any load testing not very useful.

Re: .338 Lapua Primer Question

You should be just fine but with 338 bullets and powders being as expensive as they are I would pull them and start over.

Re: .338 Lapua Primer Question

I decided to just take down the rounds. It wasn't as bad as I thought it was going to be, I used the .50 press and everything came apart nice and easy.
Thanks to those guys who offered their opinions.

Good call!

I actually use cci military primers for my 338 LM load - standard power with a magnum cup - the column of powder in the LM is not long proportional to the width so a magnum primer is not essential except with ball powder

if it is below 0, I will just stay home

You're right but I personally prefer to make my ammo useable in as many environments as possible and a Mag primer gives me that in the .338LM but I'm also in Colorado and shoot year round so..

Speer #13, pg. 37:

"In 1994, CCI introduced the No. 34 and No. 41 primers for military semi-auto rifles. The No. 34 primer is ballistically equivalent to the CCI 250 Magnum primer, and the No. 41 is equivalent to the CCI 450 Magnum primer."

CCI 34/41 ARE less sensitive magnum primers.

I actually believe that they change the anvil geometry to decrease sensitivity, rather than make a thicker/harder cup.

Re: .338 Lapua Primer Question

never saw that, I got them during the primer shortage and the info I got is they were maybe on the strong side of standard - my magnum primers are WLRM - I have never found a load for anything they do well in

I don't think that the 34s/41s are known for being benchrest accurate, but when I first got into the 338LM in early '06, I bought a bunch of loaded ammo and components from a nice guy on Ebay who shot an AR-30 out in N.M. at really long ranges and knew what he was doing.

I ended up with 100 rounds that used 300 molied SMKs, new Lap brass, Retumbo and CCI 34s. He felt that they shot well for him.

I like 215Ms, 215s and WLRMs, with the former being used in most of my ammo.

Re: .338 Lapua Primer Question

for grins I did try a few BR primers for the LM, could hear the click before the bang

Re: .338 Lapua Primer Question
