Bat Tungsten Carbide Firing Pin Weight

[M1chaelw]

Good Evening

I'm looking to upgrade fire control on my old style Bat M with the 0.250" dia firing pin.

I`ve been reading up on the tungsten carbide weights and modified spring that can be added , does anyone know if you can buy this as a kit to install?

Thanks in advance

Mike

You might consider just replacing it with the .280" firing pin assembly. The guidance is better as well.

There is machine work involved.
There is not much on the back of a Bat firing pin to thread, but there is enough sticking out of the cocking block to establish a 10-32 thread. This is what the Weight attaches too, using the cocking block as the stop.
You drill and tap the weight to fit the 10-32 end on the firing pin.
You then chuck the shroud up and bore the back out for clearance on the shroud.

As you see, this is all lathe work.

I recently bought a Bat M firing pin, which is longer, and modified it to fit my Neuvo actions. I have not installed it as of yet. With your Bat M, your option is to modify the back of the existing firing pin.

Here are some pictures. Keep in mind, this is not my idea, Alex Weever gave me most of the info on the best way to do it.
Here are some pictures. The firing pin is the Bat M I modified.

send it to a smith that really understands ignition.

Thanks for the reply's & showing the photos.

I'm tempted to get updated .280" firing pin assembly like @Alex Wheeler suggested which will leave me with the old type assembly to experiment with later down the line.

With the new type assembly is there any down side to going for the roller cocking piece?

Some nice machining there @jackieschmidt , I like the idea of the weight exiting the rear of the shroud , has this been done so you can experiment with different weights which are easier to swap out as opposed to the weights which are sandwiched between the boss at striking end and spring which would be more effort to change?

But please keep in mind, this is not my idea. I am simply following what others have done.

I have also done this to my Farley actions, which have a Remington Style Shroud. With these, you have to use carbide tooling to tap the rear of the cocking piece as the cocking piece is hardenned throughout.

If a heavier firing pin gives you slower lock time, how can it be a upgrade? Do the Bats have ignition problems?

Get the roller. It's very nice.

Since when did a gun shot off some sort of rest ever care about lock time? Maybe, just maybe shooting offhand it might help but in other scenarios not. Heavier pins have been shown in some cases to improve accuracy where attempting to decrease lock time with lighter pins and or heavier springs have shown the opposite.

I’m genuinely curious. How do you know you need to upgrade the firing pin on your bat vs a different spring?

 

[brcman]

Jackie- I am curious as to if you use the standard BAT firing pin spring or a different one?

 

[WSnyder]

Two ways I know of. If known good shooters or gunsmiths have tested and shared that a particular action shot better with a modification then it might warrant you trying it for yourself. The other is test for yourself and see if you can improve it.

 

[holstil]

I’m interested in seeing your results. If you care to share.

Reduce firing pin bounce? Longer intertia time at the firing end ?
(Meaning the bullet has time to leave the barrel before the firing pin bounces?)

Adding weight to the pin and reducing the spring weight might be a nice way to help keep the gun stable in the bags when the bolt is operated.
