Is there anyone who has first hand experience with both and would like to share his findings here.

Thanks

Norma. Hands down. Bertram is a might soft and sticky

I have experience with Norma, Horneber and Bertram cases for my 505 Gibbs.

Norma is the best brass by far, but costs about 3 times the price of Bertram. That is based on the cost of 416 Rigby brass. 505 Gibbs brass may be a lot more due to smaller production runs. I haven't bought any, so I don't really know. The Norma brass I have is resized from factory ammo that I used.

Hornebers brass is good, but about twice the price of Bertrams, and I had to resize them before loading them, (minor inconvenience) because the shoulder was a little too far forward and it wouldn't chamber.

Which is best value? Hard to say. Bertram is the thinest, being a thou thinner at the neck than Horneber, and Norma is a fraction thicker again. That will probably translate into more reloads, but I haven't worn out any of the Norma or Hornebers yet (no more than 3 reloads so far). The Bertrams last about 8 reloads, so their cost per shot is about 63 cents. You would have to get 16 shots out of the Hornebers, and about 24 out of the Normas for equivalent value. I have no feel for what is likely.

Bertrams seem to have a reputation for being soft, but that is not my experience. They don't seem any different in hardness than any of the other cases I use, so that may be an impression resulting from one of the early batches.

Keep in mind that the 505 Gibbs is a low pressure round if you are duplicating factory loads, and at low pressures you are not really stressing the brass as much as you would loading a 300 Magnum to maximum for instance. So unless you are loading to the max it doesn't make a lot of difference which brass you use. I have been very satisfied with the Bertram brass I have used in my 505 Gibbs, and will happily buy more when I need it. This is based on 3 things. 1.) It does the job, 2.) It is reasonably priced, 3.) I can send a cheque (or do an EFT) and get a box of cases sent by mail and have it in a couple of days.

The current Norma 505 brass has a thickened web, and is designed to be modified into 408 CheyTac cases ie to take the increased pressures of the 408.
I believe the old Jamison brass also had a thickened web, for the same reason.
The thickened brass should allow greater brass life.

Yep, on the old and NEW Jamison brass.
One of the early reasons Marc Jamison started the business at Jamison International was to start up production of .408 Chey-Tac brass for the Chey-Tac folks.
They make the .505 Gibbs and .408 Chey-Tac from the same blank basic cylindrical case.
The company is back in production.
Now in Rapid City, SD instead of Sturgis.
Jamison International (brass and loaded ammo) is part of Captech International now.

Agree on Norma and Horneber brass being the best. Bertram is too soft non uniform and sticks badly in my gun.-Rob

Thanks to you all, for your input.

The only brass I've ever bought from Norma is the .460Wea brass, it may had been bit soft and sticky to my liking at times, but the quality and the uniformity was always A1 for the last 30 years.

I reload everything to the limit, until the flat primer is filling the full primer pocket. If I would get consistently six reloads from the Norma brass it would be a Christmas for me.
