I guess my question would be; why? TI firing pins are expensive. They "spark" when then they contact carbon steel and don't last a bit longer.

In a 1911 semi-auto, a TI firing pin will reduce lock time by a few milliseconds. Your Winchester has a very quick lock time as is (under 15 ms) with no noticeable improvement with a TI pin.

Enlighten please?

is there any gain in going to the lighter pin? how about the spring? can the lock time be reduced?

As a general rule there minute gain in lock time is not worth the expense. There are those at the top of some speed game that may feel the need to gain any possible advantage but for most there is no real benefit. The money would be better spent on ammo and more trigger time invested.. Higher pressure springs can speed up locktime but can also reduce the life of the firing pin and cocking mechanism. Also as a rule titanium doesn't provide the longevity of steel.. In defensive weaponry some pistolsmiths won't use TI firing pins, stressing the need for reliability over any perceived control gains..

this rifle is for bench rest shooting, i,m looking for every possible edge! no matter how small. if i dont do it, the guy next to me does and beats me! it,s like racing or anything else where the competiters strive for every last bit of mechanical advantage. i,m not arguing that the advantage might be slight! i just dont have first hand experience with these mods. and wanted to ask people who did. if there was a gain to be made???
thank you!

Lighter stikers and high spring tensions decrease lock time and that's a fact. The strikers made of TI don't live as long as other materials... The biggest advantage of quicker lock times is in games that don't use a bench rest.. with the heavy guns and super light triggers I doubt that a TI striker will buy you any advantage.. Practice doping the wind would be more productive. Still if you must the only downside is the lower mass of the TI parts must use higher pressure springs or there is a chance of lowered ignition consistancy. With BR primers and that level of precision rifle construction I would guess it would not be a problem.

I have a David Tubb Ti firing pin in my 300m free rifle that is built on a pre-64 M-70 action. The rifle was assembled some time ago, but at least you know that they were made at one time.
