bushing the firing pin on a Low-wall??

1fisher
I recently bought a low-wall built in 1904, chambered in 25-20 Single Shot.

In my reading about model 1885's, I keep seeing where it is recommended to have the firing pin bushed. Is this really necessary? I am planning on shooting the gun just for some plinking fun, nothing really serious.

I understand the idea of the primer cratering or flowing into the pin hole, but it seems that it woould be much more important in high pressure cartridges.

I have loaded a few rounds using 4-5 gr. of Unique behiind a 79 gr. cast bullet with a gas check. I should be able to get out and shoot them thru a chrony in the next few days.

Thanks!

    No one has replied, so I'll make a comment. You are correct about not needing to bush your 25-20. Might me needed if the firing pin hole is now larger thru wear and etc. But, as you said, with the load you intend to use, bushing not required. However, if you had your low wall rebarreled/rechambered to a higher pressure cartridge, then there might be a need for bushing, but I'd let an experienced gunsmith determine if necessary. I had a martini cadet action barreled to 22 hornet and elderly gunsmith who was experienced working on these actions saw need to bush mine.

    What's the diameter of the firing pin tip and hole?
    You can use number drills to measure the hole.

    It is not necessary to bush the breech block and install a smokeless powder firing pin.

    Do not rebarrel/rechamber an original low-wall rifle to a high pressure cartridge... if you do, you will end up with a cracked frame.

    It is worth much more in original condition.

    Thanks for the info!

    I will post some pictures and a range report over in General Discussion once it stops storming enough to take it out.
