USAFRet,

Started using them after problems with WLRs burning through. Didn't have to change loads, still good results on target. All I use with AR-10s in .308 and .260.

HTH,

Lots of folks use them in semi autos as they’re less prone to slam fires

How is Miwallcorp to deal with?

I've bought 5K small rifle primers from them twice. Delivered within a week.

All I use noe in my Rem. R25 in 243win. after having pierced primers and slam fires using others. They are specifically made for semi autos to prevent this from happening with harder cups/les sensitivity.

But they work just fine in a bolt action, too! The equivalent of LR magnum, according to my Speer manuals.

I use them in my 6mm Creedmoor with Hornady brass. They work just fine.

I use them in my M1 Garand. In CMP matches there is a standing and prone slow fire where single loading is required. Allowing an M1 bolt to fully slam home on a round you just inserted into the chamber, is something I don’t relish. The Garand was designed to strip a round from the clip, thus slowing its’ momentum a bit to prevent a slam fire. So, easing the bolt forward a bit to lessen it’s speed before it engages the case is prudent. Never had a problem.
But, back to the primer…the hard cup of these help prevent a slam fire, in case you get carried away in single loading. No guarantee, but it’s supposed to help.
They make these in the small rifle flavor too, since AR’s have floating fire pins that will dent the primer on closure.

Thank you all. Seems like a less expensive and more reliable alternative, especially for my AR-10.

FYI. I just opened one of the 5K boxes of CCI 450 primers from Miwall.

They are labeling on the packages says 'OEM 450' 'Not for resale' 'Commercial use'.

Doesn't bother me, but, since I 'vouched' for Miwall, I just wanted to provides a heads up.

I use for my Garand and M1A to avoid any issues with slam fires

Probably not a bad idea for an AR-10. A HM buddy was shooting XTC with an AR in the standing position using Federal primers. Rifle pointed down, 45 degrees, dropped a round in the chamber, tripped the release. BAM, an AD into the ground, dirt spray, embarrassment and a loss of 10 points. Switched to REM 7 1/2 primers.

I bought some CCI 34's to try in my 300 WM because I couldn't find any magnum primers and I read they had the same mix as CCI 250. I was finally able to locate some CCI 250's and the 250's run about 30 FPS faster in my 300 WM than the CCI 34s. Now I just use the 34s in may 308s.

That wasn't the primer's fault.

100% agree.

Any firearm that requires a thicker primer cup to prevent what is called slam fire IMHO is faulty and need be removed from service until fixed !

Slam fire, what a poor term when any autoloader slams a new load into the chamber after every shot !
Further, some autos don't like slow manual feeds where instead the bolt should be released to mimic natural 2nd shot feeding.
In a hunting environment releasing an auto feeder rifle creates a clatter scaring game and for this reason they are not well liked in tough terrain where it's safer to carry a rifle unloaded.
Ground hunting with a party also presents unsafe practices when an auto can't be carried in a semi ready state like a bolt action on half cock where safe hunters also use a finger to ensure the bolt never gets accidentally closed until a chance to take game presents itself.

Who would put others at risk with any firearm that can slam fire....I'd rather get it fixed pronto or cut the bloody thing up !

We need have a pinned thread about all autos that slam fire for prospective purchasers to be properly warning about such faulty engineering.

They will make a good baseline in your AR-10 since they were designed for auto and semi-auto applications.

The main difference between #34 and commercial primers, is that the Mil-Specs include more requirements.

One of the more important features of the spec to you, is that the activation energy has a tolerance on it that means it shall not ignite below a certain level. Commercial primers don't have that requirement, (although many can pass it). This protects you from firing pins slamming on them when the bolt cycles.

$47.65 shipping? Yikes!

 

[Deleted member fkimble@charter.net]

Yea, they suck you in with the low price and stick it to you with overpriced shipping and HAZMAT.

I was given a couple of hundred of these and used them interchangeably with regular CCIs in some cast bullet loads. No differences noted.
