First my post got duplicated, now it is gone alltogether the forum still has bugs. This was a long post and I hate to write it all over again. But here we go again, also not the same.
Lee springs is in England and is friendly to ignorant spring buyers.
10 for 50 bucks. Suitable sizes available. .240 O.D .038 or .040 wire .700 long. Should order 10 of each size and charge 15 bucks a piece to 10 prepaid users. Includes shipping and handling, owner is responsible for fitting and seat modification.
My firing pin has 41 Thou projectionn with the hammer blow but can be pushed out by hand to 70.5 thou. It has 30 thou free float before it hits steel to steel. This overtravel should prevent the pin from hitting the bottom of the seat when the spring is in place it too will stop travel past the 41 thou which is determent by the notch in the hammer, You may need to deepen the seat a few thou?
I will strip down the 6x47 frame and check out the firing pin see what I have and will let you know. It too has way too much resistance and needs the return spring shortened. At present I have some CCI small match primers that the hammer wont set off. But these primers were to hard to fire in my 6ppc BR rifle. I thought the hammer would set them off.
I try a new hammer spring.
One other thing I have done is lower the hammer extension with a needle file for more rotational hammer speed. You can't get too much but every little bit helps ignition. So far the 257 has worked without a hitch. But has not fired many rouns with the new hammer spring.
Wolff needs a design for the springs. Number of coils, angle of coils, diameter inside and outside, wire size, compression in pounds at complete closure. They have the pardner hammer springs if they work???
I talked to the manager, got his name somewhere.
Hope this post is not getting lost again.
