Have you tried other ammo in this Rifle, can you post a picture of the fired cases that have primers in them. Is this the POF model with a gas piston operating system.

That is why you see crimped primers.
They are not getting blown out, rather they are getting thrown out.
The force of the action causes the primers to come out.

If the primers were blowing out you would have a much more violent result.
