[QUOTE="yorke-1, post: 1643512, member: 11960"] Instead of grinding down your bolt body, why don't you try shimming the rear bolt baffle? The primary extraction happens when the ramp on the bolt handle comes into contact with the ramp on the rear bolt baffle. You can change that engagement by either bringing the bolt handle closer to the rear bolt baffle or you can bring the rear bolt baffle closer to the bolt handle. Try just shimming the rear bolt baffle by applying something like aluminum muffler tape to the back side of the baffle which rests against the rear of the action. Add a couple layers at a time and then test your primary extraction. The other way is to insert a feeler gauge and get an exact measurement of how far you need to move the rear bolt baffle to get the desired contact. Once you've determined how much you need to shim the rear baffle you can make shim of the proper thickness. If you want to get fancy you can drill and tap the rear bolt baffle to accept 2 or 3 brass set screws so that you can actually tune your primary extraction. The other easy way to fix this is to just try a different bolt handle. More often than not, that works wonders. [/QUOTE]
