Primed 30-06 with LPP by mistake gonna work????

[Don McDowell]

When you look at pressure tested data for things like the 454 casull, 450 sw etc, one has to wonder why is it ok to use large pistol primers in those cases?

 

[GLOOB]

I think those cartridges are spec'ed for rifle primers. I assume you meant 460SW. Large rifle for 460, small rifle for 454.

I'm sure MOST of the time you'd be fine using LPP in place of LRP. But the factory making those primers certainly aren't going to stand behind it. If they get reports that their LRP are piercing/cracking under normal use, they'll do a recall and fix the problem with their metallurgy. And they may pay for firearms that are damaged. When they get reports from some nutjob piercing LPP in a 60kPSI rifle load, they'll say "so?"

A couple of years ago we had a guy shoot a club highpower match with .223's primed with small pistol primers. He was shooting an AR15, it ran fine.

Next weekend he brought the AR15 bolt and some of the cases in to show everyone. The bolt face looked like the surface of the moon with an almost perfect circle of deep pits where the primers had been gas cutting into the bolt. Almost every one of his fired cases had gas cuts down one side of the primer.

I have a pic of it somewhere, I'll see if I can find it.

What I take away from this thread for myself is "don't take chances in reloading". What might be safe 99 out of 100 times can get you or someone else hurt or your weapon damaged on the 100th time.

I've not been reloading very long, but this forum has continually stressed safety first. Let's not take shortcuts to save a few minutes of work or a few dollars.

side question, other then aesthetics, what are the drawbacks of a pitted bolt face?

Well had a box of 900 WLR primers and a sleeve of 100 WLR primers so a while back just put them together grabbed 3 sleeves and while priming noticed the 100 I was about finish were..... yep Large Pistol primers.
So I got 100 30-06 cases with large pistol primers, Who else has done this and has it worked? Just loading plinkers, Yeah they seat a lil lower but i dont think that will be a problem will they ignite most rifle powder?

This subject has been beat to death x 1000. I've personally fired a few cartons of LPP's in various 30-06's (1903, 03A3 and 1917), 308's and mostly 7.5x55. I've used far more Winchester LPP's than any other but have also used several hundred CCI300's and 350's. Mind you, these are all with cast bullet loads.

Also remember that many of the current gargantuan handgun cartridges do/did use LPP's with their very high pressure loads.

If you're firing light plinking loads, proceed. If you're firing maxed out hunting loads, I'd knock the primers out and start over.

No drawbacks at all (besides aesthetics) unless they get bad enough to involve the firing pin hole. At that point on many bolts it's common to install a firing pin bushing. On something as cheap as an AR15 bolt, just replace the bolt and verify that the headspace is still good.

I would not shoot pistol primers in an AR. There is no spring to hold back the firing pin. The fire pin will dimple a new round after firing the preceding round. Use rifle primers in this situation.

Jeeptim, one additonal comment. I noticed you said you could now tell primers apart if kept in a glass jar. I would under no circumstances recommend this practice. That many primers in direct contact with each other is an accident waiting to happen if the jar was dropped.

I think he was just making fun of my SIG line!!
