Yes, its true. It really does exist. Mine arrived today.

Mr. Horneber has nothing on Jamison now. Get yours before Marc comes to his senses and raises the price. They have the same head strength as the .408 Chey-Tac, which is 70,000 PSI brass, even though the CZ .505 Gibbs is only proofed to 55,000 PSI. Must have something to do with bolt thrust and lug shear?

The best part is that the CZ's bolt will close on a new Jamison case, and the primer flash holes are perfect, look drilled instead of punched, unlike the A-Square made stuff. I am ready to load and shoot.

Good news for you and the CZ .505!

also received my cases yesterday! Comparable to Horneber and the weight feels heavier towards the head. Rim was a tad thicker and start of the shoulder a bit sooner, making for a little extra positive headspace in my rifle.

Good stuff from the looks. Can't wait to go thru the wobbley bertram.

How do the prices compare with Horneber?
What's the source for the brass?

Introductory offer price by Jamison was only $1 per case, plus $6 per 100 for shipping. I hope he raises his prices before he goes broke.

Horneber: $4 per case???

A-Square: $8 per case

I called Marc Jamison today to ask what he thought of the CZ headstamped, made-by-A-Square cases I sent to him for inspection.

Where to begin? He said the heads were too soft and the rest of the case was too hard. Wierd, I say.

Basically on the A-Square case: I say it was a total mess, and a crooked thing to sell the loaded rounds for $12.50 per piece.

The A-square flash holes were a total joke.

The Jamison flash holes are punched, but properly and beautifully formed in the head like a .408 CheyTac.

RIP,

Have you weighed the brass and checked it for neck thickness consistency?? Just curious, any additional comments would be appreciated.

Hi Bryan,
I just picked 5 at random for you, and weighed the Jamison .505 Gibbs brass:

from lightest to heaviest in grains:

368.0
368.3
368.5
368.7
369.2

mean = 368.54 grains

standard deviation = 0.4 grains

That is only about 0.1% of weight for the standard deviation, about 1 part in 1000.

The necks were eyeballed and look very uniform, beautiful.

This is undoubtedly some of the best brass possible.

Get'em while they are cheap. Demand will drive prices up.

Price is $1.25/case and $15 shipping. 100 on the way If you have cases and some bullets, is this sufficient cause to build/buy the rifle in said caliber?? I'm thinking yes. I have a Brno 602 custom in .460WM as a donor rifle but my 'smith says opening the bolt face for the big Gibbs rim doesn't leave much.

I have a 505 Gibbs built on the 602. Your smith is right there isn't much material left, but there is enough.

Good luck with your project.

It is about time the price went up a bit. Still dirt cheap and rising.
