I have several boxes of Combined Technology Failsafe bullets that I want to shoot but my rifle has never had moly coated bullets and I didn't know if I would be getting myself into trouble by shooting them. Can I remove the moly or is even a problem to shoot 100 bullets in a hunting rifle and then switch back to naked bullets? The third option is to trade or sell them. They are 7mm 140 grainers and the rifle is a 7mm STW. Thanks. Tom
