Henry big boy steel 45 colt bore diameter?

[autogun]

Has anyone measured? Henry tells me that is proprietary information and they will not provide. Thank you.

Clean the bore really well, then slug the bore. Bore diameters differ per firearm.

I slugged mine when I first got it. Slug measured .452"

Why would Henry consider that proprietary information? That doesn’t make sense to me. But then, a lot of things don’t make sense in today’s world.

You ant to be smart enough to figure all this out by your selves ?

[DougGuy]

Bore diameter = land to land measurement.

Groove diameter = measured across the grooves, i.e measuring a slug.

Thanks for all the replies. CastingFool thanks for the measurement.

You're quite welcome! Having worked a few years as a machinist, it's difficult to drop activities you used so often that just became part of you. When I use my planer, I also mike my boards.

I never bothered to measure mine bought last September but, out of the box, it loved the same boolits as my Blackhawk which are sized to .452. it was what I hoped for.

Same here, with my all weather side gate 45.

It's probably not, more like a blanket response to technical questions that the customer service rep can't or won't answer. It's either 'proprietary' or, "All of our barrels are made to SAAMI specs. Is there anything else we can help you with?"
