7PRC Hornady Brass issues

[Rosebud]

I have a new Fierce Carbon Rogue in 7 PRC. I was unable to get anything but Hornadys brass at first.
Which is the issue. New unfired cases that were run through a full length size die, then annealed and run through a forester neck bushing die, also full length. Almost half of them were difficult to chamber. Even the once fired were problems. Then I started bumping the shoulder back, 2 thousands. Then four thousands. Ended up at eight thousands before the became fairly easy to close. I got my GS owner to let me try some factory loads. They worked without issues. I was frustrated by this beyond words. I was shooting hammer bullets, which were wasted in my opinion.
I've sense found ADG brass which is supposed to be here Thurs. I'm leaning on the bag brass from Hornady being some that were not up to standard for their loaded ammo. I already didn't like Hornadys brass, now it's on the hate list.
I know the 7PRC is very new cartridge, but is anyone having any issues with brass or other loading problems.

Did you try and chamber the new brass that was unsized? I bet they would be fine. A touch undersized if anything. I neck size new brass and that is all. Why anneal virgin brass?

Your problem may be your FL sizer not being adjusted correctly to size the virgin brass. I can about guarantee it.

I bought 700 rounds of factory Hornady 175 eldx and after reloading 5x primer pockets are a little weak on some so I toss those but I'd have to agree with these guys your sizer is out of wack. I now run ADG as I just picked up 400 new cases but I still have a lot of factory to run . I always try 3-4 out of every 10 cases to make sure they lock up tight

Hornady brass is junk, lasted 2 firings then primer pockets were gone. I am on 5 or more with ADG and pockets are still great

Could your Interference be somewhere other than the shoulder?

Yes I did, before I did anything else.That's why I full length sized all of them using a lee die. I've ordered a micrometer to measure the web.

I'm thinking that the web is out of spec. Micrometer is coming just so I can measure.

 

[Rosebud]

Factory Hornadys match ammo chambered without issues. Just slick as snot.

Use a marker on the web area and shoulder. That should tell you where the interference is

All of my complaints aside, I'm loading a 6.5 PRC for a friend using Hornadys brass without issues. I'm at a loss as to why this is happening except bad QC on their bagged brass.

I can't get my kendel to pair with my phone at the moment or I'd show the pictures of the brass.
Finally got a picture.

I full length sized using a lee die. They are not difficult to set up. When that didn't work I used a forster full length neck bushing die. I've been using them for couple of years. Don't think both are bad,or mis adjusted.
I did mention that not all the brass wouldn't chamber, only about forty percent were bad.So sorry about that. Frustration has set in.
