Ed Plummer retired in 2007. He sold his operation to Wayne Jacobson. Which isn't to say that AHR doesn't do good work anymore since Ed left. Wayne worked with Ed before the shop changed hands, so I'm sure the quality now is just as good as before the transition.

Just to clarify my previous post. CZ-USA doesn't manufacture the CZ product line. It is a wholly owned subsidiary of CZ in the Czech Republic. It is the US distributor of CZ products, and also the warranty service center.

I suppose the fact they recently set up a custom here in the US muddies the waters a little, but they still don't manufacture the off-the shelf products. I pulled out the paperwork from my files just to make sure I had my ducks in a row. My CZ550 Safari Magnum was also distributed by CZ-USA. But the paperwork clearly states it was made in the Czech Republic.

So, as I said, I'm unclear as to how a rifle manufactured in the Czech Republic to CIP standards and proof tested at the Czech government proof house could have possibly slipped through without being properly chambered.

Second, when a round of ammo doesn't chamber in a rifle, there is more than one variable involved. The ammo also could be at fault. That would be my first suspicion, not only for the above reasons but also because my CZ550 in 416 was delivered to me with a test target. I'd take that as evidence that it functioned and fired with whatever ammo the manufacturer used. I'd first try to find out what type of ammo the manufacturer used to test the rifle. Then determine if the ammo I used, or if reloads the dies I used, were manufactured according to the same set of dimensions.

I obviously don't have any experience with the "Safari Classic" line; are you saying they charge several order of magnitudes over their regular line of Safari Magnums, but don't proof test or function check them with the same rigor as the lower priced models? There wasn't a test target included with the paperwork that came with the rifle?

I'm not saying that such things as a 505 Gibbs rifle that won't chamber 505 Gibbs ammo can't happen. There are tons of stories of S&W N-frame revolvers being shipped with barrels marked and bored for 44 mag ammo and cylinders bored for the 41 mag cartridge. S&W had its quality control issues, too, during its history depending on what consortium owned it. But S&W revolvers weren't sent to an independent agency to be double checked and proofed before being shipped.
