    I was planning on buying a Henry Big Boy Case Hardened .44 but I kept reading threads about different twist rates. I was mainly interested because they are advertised as having a 1 in 20 twist. However, numerous folks have reported on line that their rifle has 1 in 38 twist. For those of you who shoot .44 long arms, you know the 1 in 38 twist sucks except for .44/40 ammunition.

    Anyway, I decided to ask Henry what the real story was and here is their answer.

    Thank you for owning a Henry John.

    While we made a running change in Production to 1:20 for this model, there was considerable bbl Inventory of 1:38 remaining which led to a mix being built/shipped.

    Unfortunately, there isn't a serial # range and only visual inspection or measurement will confirm ROT.

    Based on this, I am not going to be buying one through the mail, that's for sure and I don't see them showing up in stores to check out the barrel twist. I guess I am going to wait until they use up all the old barrel stock. :mad54:

    While I can't blame Henry for wanting to use up inventory they should have done a specific run of .44-40 rifles or some kind of commemorative where that rate of twist would have been appropriate. They could also have sold the barrels to Numrich or another surplus oriented company.

    Or they could have at least tracked the serial numbers. I don't understand making an engineering change heltor skeltor knowing the significance of the rifling twist. :crazy:

    Would you guys edumacate me please? I own a Big Boy Classic (Brass receiver).

    Would this be subject to the same running change?

    What's so bad about 1 in 38?

    How does 1 determine the twist?

    Thanks!

    You can find the twist of your barrel by using a cleaning rod and a tight patch. As you insert the rod, it will spin with the rifling. Use masking tape and draw a dot on it so you can see when the rod has made a complete revolution, then measure how far down the barrel it went.

    You probably have a 38 twist. That is, twist rate is such that your bullet would make 1 complete revolution, in every 38 inches of barrel length travel. Or a half of a turn, in 19 inches etc. Try the link below for a visual. Then you can check your rifle, and you'll know for sure.

    If you are shooting "typical" 44 mag factory ammo? Say standard 240 grain? The 1 in 38 twist is fine. But when the desire is to shoot some of the heavier (more properly longer) bullets, say cast bullets of 300 grains and up, they will require a faster twist to properly stabilize them.

    Original 19th Century .44-40 rifles had 1:38 - ish twist . It worked fine with the 205-215gr bullets of the era . For many years before the were purpose built .44Mag rifles , .44-40 Win M92 rifles were converted . And again 240gr bullets worked within expectations .

    Continuing the theme , for many years Marlin continued with 1:38 - ish .

    ( The reason in the beginning was , slower twists were more forgiving of BP fouling when BP was the only powder .)

    But as heavy bullets became more common in.44 Revolvers , people tried them in their .44 carbines also , and accuracy was inconsistent at best with slow twist .

    The nice thing about the Henry is the receiver is a little longer allowing for the heavier .44 Mag cartridges. I worked the lifter in my Marlins and Rossis to get 1.65 but that's about the limit on those.
