Lil Bro. Power65 here. The reason you are having pain in your shoulder is because you are slowly crushing your AC Joint in your shoulder when you go RAW. When lifting in a shirt this joint is supported by the shirt with the chest panel of the shirt. I wish I could draw you a picture here. Let me try to explain this without using medical terms. The AC Joint is really not a joint, but more like a bowl made up of the three muscles that make up the shoulder; ie, your delts. You have the Front, Side, and Rear. OK. These muscle make up a "Upside Down" bowl if you will that fits on the side where the arm attaches to the shoulder area. That's called the AC Joint. When you go as wide as you do the bone of the arm is compressed into the Soft Tissue of this "joint" therefore making that soft tissue inflamed and sore the day after. This can go on for awhile, but after time this tissue will be damaged and start to form scare tissue within the joint. That scare tissue will start to form a Web like mesh in the shoulder that will cause all kinds of pain and eventually end your lifting if not removed.
Actions to take: You may need to move your bench in when lifting raw. I have my little finger on the mark. Yes you will be a little weaker at first because this puts more on the Tris. But over time your Tris will become so Freakin Strong that when you do move your grip out in the shirt you will have better lock out power. PM if you have any other questions. I've trained several guys including myself that have had this problem.
