7PRC Partition wont chamber

[mtnbound]

Update. Got home this evening after borrowing a few 7mm bullets from a friend.
I loaded 162 gn Hornady sst @ 3.337 - wouldn’t chamber
I loaded 150 gn sierra matchking at 3.268- wouldn’t chamber
I loaded 140 gn Barnes ttsx - wouldn’t chamber
I loaded a 185 Nosler rdf at 3.439- wouldn’t chamber.

So then I decided to reload all these at their book length from their manufacturers book data.

So I loaded 162 Hornady sst at 3.070,
I loaded a 150 gn match king at 3.100
I loaded a 140gn Barnes ttsx at 3.110
And I loaded a 185 Nosler rdf at 3.320

I can get these to chamber if I force them. The rdf was so rough that it seated the bullet to 3.317.

Most importantly I’m noticing to chamber any of these bullets even a lil shorter than book length in order to get them to chamber when the bolt should rotate I’m having to force the bolt further I’m assuming jamming the bullets into the lands and I can feel the extractor snap over the case rim and then the bolt will rotate down. I have other tikkas and I went grab all of them and none of them have this phenomenon. Or feeling. What say you?

Something is messed up with the barrels' chamber. When you talked with the GS, did you ask him about the 2 spent shells and what load he tested your system with?
