While I searched high and low for a new striker spring for my S&W 1500 rifle, I found firing pins made for 243Win rifle.
Do any of you know what the difference might be between a standard firing pin and a F/P for other calibers? Thanks

Didn't know S&W ever made rifles. Sure it's not a branded S&W made by someone else?

Since a .243 is a necked down .308 it would seem logical the firing pins are identical. If my aging memory serves those rifles were made by Howa for S&W.

I think the first S&W rifles were made by Husqvarna then Howa.

I measured the power of the stock spring to be about 15 pounds, below optimum for best accuracy 20-23). So, I made mods to the bolt shroud and firing pin to accomodate a stronger spring, which is now about 21 pounds.
My rifle is 250 Savage Improved in a wood, sporter stock which is not conduce to bench testing.
Watching the wind and wind flag closely is the new frontier for me.

That is correct and all of them were built with Mauser actions.
