Testing a new InLeadWeTrust barrel with the CF-W bolt. was getting light primer strikes with newer CF-W recoil spring. It did not have enough inertia to hit primer properly. Advised by CF-W tech dept to reinstall the original recoil spring the bolt came with (did not cut any additional coils off other than what was done by mfg). And bingo! It works great! Newer barrels have tighter chambers and take more bolt inertia to go forward to strike primer properly. Love this barrel and it's features and absolutely cannot say enough about the CF-W bolt, it's inventor and partners. These guys are top notch all around. You will definitely not regret buying one!
