I am not a professional gunsmith nor do I play one on TV.

that would be an issue with the chamber being concentric with the bore and head spacing rather than the mainspring and firing pin. Do I think a heavier mainspring and lighter firing pin will decrease lock time? Yes I do. In fact, I run a lightweight hammer and titanium firing pin in my match AR15. It definitely helps to improve my off-hand scores.
I don't believe the majority of people will notice any benefit in a hunting rifle however. Well..... maybe if you are shooting hunter class bench rest competition perhaps. Other than that, it's probably just a waste of money for most folks. Again -- just my personal opinion which is worth absolutely nothing.
