I understand why you came to that conclusion from my description, but it is a bit difficult for me to explain. First of all my follower was not OK. Here is a picture with the standard follower. The bolt slips over the rim of the last round every time. Next picture is where I milled 0,5mm of...

Maybe I was not clear enough. The last round is not a problem. Only when there are more than one in the magazine. When the top round is to the left the lower round will be to the right and vice versa. Putting upwards pressure on the lower round will force the upper round to the opposite side...

In my rifle the lower round will jump out when the empty case is ejected but only if one is pulling the bolt back forcefully which is necessary to eject the case. I am careful with the feeding ramp and only touched the lower edge, so strength is not affected. I am with you a 100% about the...

Yes I have. That fixed my problem with the bolt sliding over the case rim as the right round will sit more to the left and therefore higher. I fixed an extracting issue by fitting a new extractor. I did a minor adjustment to the feeding ramp so my long loaded wide meplat solids do not jam...

My rifle is built on a CZ 550 Magnum custom action. It is not born as the 500 Jeffery it is now. The problem is not the rails but the area underneath the rails. A standard 550 magnum action is a bit too narrow for a fat round like the Jeffery and the rounds are not spread wide enough. There is...

Would anyone care to share a couple of pictures of how the undercut is done? I have the same issue with a CZ 550 and rounds popping out.

I finally found an extractor at a local gunsmith. Put your CZ spare parts in your safes. Scarce as hens teeth these days.

I thought I was a wirdo. Well I probably am, but now I know I’m not the only one. On my home office days, I like to have one of my Colts lying on my desk and a rifle in the corner. Just makes me happy looking at them.

Actually the Danish lead ban is max. 1%, which makes it even more stupid. We cannot use normal brass bullets for hunting anymore as ”turning quality” brass typically contains about 2% lead. We have used pure lead for hundreds of years and reducing that to 2% is still not good enough. My own...

That”s 55k psi and yes we do run much higher pressures in that action. That is why I am thinking it must apply to the largest calibers where bolt thrust might be an issue.

One of my CZ 550 Magnum rifles has “Max. 3800 bar” roll stamped to the side of the action. I am not quite sure how to read that number. There is no pressure inside the action, only bolt thrust which of course depends on the diameter of the case, all else being equal. I have seen the 550...

I got in touch with a Czech dealer who called the CZ factory. Practically no more spare parts and nothing can be backordered. Such a shame for the thousands of CZ 550 owners. Still looking for an extractor..

Update if anybody would be interested: I talked to the bullet manufacturer today and he claims that due to this bullets design and the low engraving force, they do not see any pressure spikes even with zero bullet jump. He insured me that my 0.5mm was completely safe. It would be nice with...

No these are my first 500J reloads but you already new that. I am a very active ELR shooter and I shot 50BMG for 10 years until they were banned here. I used 802gr. brass drive band solids exclusively and I have never had any issues with 0.5mm or less jump. I wonder why the Jeffery is so much...

In my 30 years as a reloader I have never heard of the need for such a big jump pressure wise. I would say that 0,5mm is pretty much standard as a starting point and sufficient for not raising pressure. Especially drive band bullets can be seated close without pressure issues. I have loaded up...
