1871 Springfield

Does anyone know the thread size for the tang screws on an 1871? I need longer ones than what's there is I can mount a sub base for a tang sight. I don't want to drill hoes in the tang.

Re: 1871 Springfield

Agreed. They drop in easily and extract smoothly. By the way, using a digital caliper to measure, the difference between outside of muzzle to land, and outside of muzzle to groove is around .011.

Re: 1871 Springfield

I didn't do a chamber cast, but loaded rounds drop in easily. Haven't shot it yet.

Re: 1871 Springfield

He did three measurements on the slug and between the three there was only .0005 difference.I'm inclined to accept his numbers. The bore diameter is .5012, meaning that the groove depth is what's unusual. My 1868 TD is .515 groove. I have a mould that casts .526 bullets that I have been able to sque...

Re: 1871 Springfield

The Springfield version does indeed have a three groove barrel. I didn't measure the slug myself. A gentleman who has done a number of other odd number slugs for me measured this one.

1871 Springfield

I have an 1871 in nice condition that is a shooter. I recently slugged the bore out of curiosity. Surprisingly, at least to me is that the bore is the usual .500 or so, but the groove size is a bit over .524. I was expecting it to be around .515. I have been shooting .517s in it. Has anyone run into...

Re: Trigger pull weight

Thanks Dick.

Considering it's being sold "as is", I think I'll pass.

Trigger pull weight

I recently saw an ad for a single trigger roller that had the trigger pull weight altered down to 1 pound, which does not appeal to me. Can it be made heavier after doing that?

Springfield 1871

I'm considering an 1871 project gun. Besides a rusted bore demanding a reline, it has a problem with the hammer not always returning to half cock when the block is closed. Am I correct that this is probably related to an issue with the trigger group unique to the 1871 and NY State models? I've looke...
