[QUOTE="BrentM, post: 971752, member: 61747"] Which leads me to believe the 260 and you are not meshing yet. It also might mean, since you can shoot and you have proved that to yourself, there could still be flaws in your reloading process regarding the 260. Check perhaps these items: Powder scale consistent Weight sort your brass flash hole shaping Switch primers- We had a bad batch of CCI. I use federal match. Concentricity of the loaded ammo. Bullet alignment is critical. Neck thickness and tension. Do you neck size? Shooter: One thing that can lead to inconsistent velocity is how you shoulder the rifle. For example, if you put the butt of the rifle against the wall vs against nothing and fire it, the round fired against the wall will have a lot more velocity, simple physics. If you shoulder the rifle really hard, then light, then medium, then hard, the POI can can change. This is why SD on people who chrono ever round can vary. Some people use a lead sled to shoot better groups and dial a load. Although I don't use a sled, you certainly could try one and see if changes the POI on your current loads. You could fly to Idaho. Bring your rifles, reloading dies, etc. whatever you can get on the plane and I will spend a few days with you. [/QUOTE]
