Twist rate model 1892?

[andym79]

Hi does anyone know the twist rate for a 1903 model winchester 1892 24" in 38-40.

I have come across conflicting comments from 1:24 - 1:30 - 1:36.

Thanks

I think you're getting the conflicting information because the earliest ones were designed for lead bullets and black powder. The later ones where changed for more modern cartridges.

I don't have your answer sorry, but hopefully that will help you narrow something down a little?

I have in a little Winchester book here that the rifle twist for a model 1892 chambered in 38-40 was 1:30 from 1892 until 1905.

Ta da?

Oh, and after that it was changed to 1:24 for smokeless rifle powder loads.

That explains two of your answers. Not sure where 1:36 comes into it.

Hope I helped.

Probably people mixing it up with other calibres.

e.g. .44 mag and .44 colt are 1:38 twist I think.

Hi thanks a lot for that!

I have been shooting it with a 2205 load. If its pre 1905, I wonder if I should be using 3F powder?

I dunno, should you? How's it grouping with 2205?

Pressure signs etc?
