Who has a Cylindrical grinder to grind some Tungsten?????

let me try to explain it in simple terms....a heavier firing pin needs less spring force to set off the primer, less spring force makes for easier bolt lift, lock time means nothing in SR BR, being able to rattle off 5 shots in 17 seconds without upsetting the rifle on the bags means everything in the world when picking a lull in the wind to shoot through........

Hey Cy, anyone with a lathe can do the machinable tungsten, PM me for the company in Ontario to get your new springs from.
I would also call Mick and maybe Smith and see if they are interested, they also hae a better understanding of the principle behind it, shot of that fire a PM to Juan Valdez here and walk him through it, it may become something he wants to add to his services list for future customers and builds.......
 
Thanks YoDave for the input. Will definately get that info from you.

Dennis yes you are right in bringing the weights in and selling. The key would be to get the appropriate springs. Looks like YoDave may have the solution for that. I found a place in Illinois that specializes in Tungsten I just need a 1/2 hour or so to pick there brains to understand more about the material and its machining.
 
I think there is a lot of mis-information about tungsten. A lot of people talking about tungsten are in fact referring to tungsten carbide which is a substance used in high grade machining bits and such. It essentially is cast to shape and ground using diamond should it need any additional shaping as it's too hard for anything else to cut.

Tungsten itself as a metal is quite brittle which is the only real difficulty I could see in machining it. That said I'm sure they have a machinable alloy of it on the market...finding it may be a different story.

Or someone suggested gold may be a cheaper option should one have a good goldsmith nearby. (and then you can be the man with the golden firing pin... :p )
 
Guys bare with me. I am not a machinist by trade so I do not know anything about metals. I know what aluminum, SS, cast, may be, that is all. In doing my searching when I use the term Tungsten I have come to realize that what I want is the highest grade Tungsten alloy that is still machineable without any specialized tooling. I understand it is an alloy that is used but the thing about it the higher the tungsten content the heavier. That is what is needed.

The weight that I have right now is .600 long x .441 outside with the hole drilled and is not to far off of 1 oz in weight.
 
So it seems that BR shooters don't care too much about lock time? (BTW I would agree with that - I can't see any pressing advantages to be had in BR or F-Class from fast locktimes)

If the requirements are:
- easy bolt lift
- strong, consistent firing pin strike

Then what's wrong with adding mass to the firing pin somewhere other than the highly-space-constrained region inside the firing pin spring? Why not just drill and tap the back end of the cocking piece, and add some weight there? (Plenty of room for it, no need to use expensive/exotic materials, and you could easily add/subtract weight there)
