Try some flat base bullets and see how they group. In my guns they group smaller than the boat tails.
Don’t have any on hand at the moment, but plan on trying 150 gr Interlocks. The factory Hornady American Gunner 155 bullets are accurate, but slow. I am trying to get the same accuracy, but with a faster velocity. The Hornady ammo is just below 2500 fps. I am just passing 2600 fps with the hand loads. One problem with the 155 bthps is that they have a very short bearing surface. Makes it hard to seat them straight.
