My dimensional study shows that with typical cast bullet dimensions and brass case wall thicknesses, my bullets and cases each give about a thousandth. Pulled bullets show that about half of the bullet's give comes back because of elasticity of the lead bullet so the net of this is that with typical dimensions that bullet should be comming out of the case only about a half a though under the sized dimension, or in your case .3575.
Something else is going on.
