Howa 1500 6.5 Creedmoor Issue

I got this rifle last year just before deer season and shot it 20 times before season. I went out today to check zero. I am shooting the Federal Barnes TTSX 130 gr box ammo. What I noticed is that the bolt was slightly difficult to lift after firing a round. Much like when you start getting over pressure signs. I tried Hornady performance and same thing. I got home and tried putting a spent brass back into the chamber. I had to force the bolt into battery. Anyboyd have any idea what might be going on? On live round going into battery is no issue. Something is off and don’t know what. Thanks to the brain trust.
