300 Black Out, Hornady Case Reloading

[SMSgtRod]

Is anybody else having a tough time getting primers seated in these cases? I mean I have chamfered and reamed
a lot and they still can be near impossible to get a primer seated.....

I purchased 50 Sig cases and the primers drop right in.

Anybody got a fix? I mean other than buying more SIG cases.....

Called Hornady today. Technician said that the crimp that they put on the case is very heavy.
Therefore a lot of material will have to be removed to be able to seat a fresh primer.
So, if you are trying to reload some of these cases.... give them a good reaming!

Wonder why they crimp the primer heavy-the .223 or .556 NATO they both have a working pressure of 55,000 PSI

Have a 1000 rounds of 5.56 that just bought. Betting that it has a heavy crimp on the primer too.
New brass on the other hand has no crimp (duh, no primer) so the primers punch right in with ease.

Sig 556 cases?

I would post the topic change that you yourself changed, but I won't. This has gotten too sensitive!

 

[SMSgtRod]

You've lost me now

 

[TEXASforLIFE]

You went from Hornady to Sig

 

[TEXASforLIFE]

The crimped case Hornady 556 only or/and 223rem also. Not sure if that is another thread? This is on your call to Hornady.

Post #2.

Sorry you went from 300bo to 556 cases. Now I'm confused?

 

[TEXASforLIFE]

Well I'm no help for the 300bo Hornady cases/ammo. The ammo/brass that I have/use are a different brand and have no issues with about primer problems.

 

[SMSgtRod]

SIG makes 300 BO cases.... that help?

 

[SMSgtRod]

krunchnik was comparing 223 and 5.56 for crimp comparison.

 

[SMSgtRod]

So I replied that I had 1000 5.56 and after I shoot some I'll try reloading them to see
if the crimp is as heavy

 

[TEXASforLIFE]

Was Hornady heavy crimping their 300bo ammo?

 

[SMSgtRod]

So no I didn't change the subject, another member did a comparison which is really fine.

 

[TEXASforLIFE]

Just a heavy crimp and/or sealed primers also?
