I read his post on another forum, https://www.snipershide.com/shooting/threads/grendel-like-belted-magnum-problem.7112215/,
And if I understand it correctly he is running the rifle suppressed, that would explain the sooty cases.
He also ran the same load on other brand cases and did not have the belted case. It wasn't until he started loading the Lapua brass with the same load he used with Hornady brass.
I read something awhile back about a Grendel having the same exact issue using Lapua brass, that is were I saw the cut a way cases and the difference between them.
My pet load is almost the exact same load he is using. But your rifle may like something different.
29.4 Lever
105 Nossler RDF
CCI 450 Magnum
Hornady and Starline brass
I have never had a belting problem in 5 different rifles. And I have loaded more grains during load development and for my bolt gun. But I use Hornady brass for the hot loads.
The issue with swipe marks is a characteristic of this caliber, even Hornady factory loads do this, maybe not as bad as he is seeing but non the less it happens. My fix for this was to remove the ejector and radius the sharp edge and round it out to not cut in to the case head. And if I was him I would only use magnum primers if he already does not use them. They are a little bit more durable than standard primers. His primers do not seem to be flattening out but do look like they are flowing into the firing pin hole.
Bottom line is if you are having problems with a certain component you are using, stop using it.

If you can not see the tyranny of having a gun ban enforced by men with guns... Then you fail to understand why the second amendment was written in the first place.
