Hello, The bolt on my Mauser is a little tough to open, and I'm wondering if the contact area between the bolt handle root and the cocking ramp on the receiver is too narrow. I took some marker and drew over the area on the bolt handle and worked the action a few times. The bare spots on the ends of the bolt handle root are ~1/8" and the center portion is closer to 1/16". Is that level of contact considered good? Would increasing the contact area (through light and careful polishing) make the bolt lift easier and smoother?
