viperidaeWill a Ruger #1 barrel fit a 77 tang safety action?
Specifically can I have a .45-70 #1 barrel fitted to a 7mm Mag 77 tang safety, set back a hair, and rechamber to .458 Win.?

dpcdYes, the threads are the same. Ruger barrels are not timed anyway, and of course you will have to make it index up if you want the rib on top.
Realize that the 45-70 barrel will make a super light 458 and will kick a lot. Like, really a lot.
I'll trade you a real 458 barrel for it.....

To do a proper job of it, the No. 1 barrel would have to faced off about .150" (more than a hair) to get rid of the ejector slots, the shoulder would have to be set back as well and probably far enough to get into the rear rib screw. Given the costs of a complete job: labor for the barrel install and iron sights, using a used barrel intended for an altogether different action has little merit.
As DPCD is want to recommend, a superior alternative would be to start with a new Douglas barrel. Douglas can chamber, thread & polish the new barrel at bargain prices. If a rifle has a heart, it's the barrel. No reason to use questionable take-off components when a superior, new barrel is readily available.
Cheers & Happy New Year!

J WisnerI know of a Winchester 70A rifle running around that has a Ruger # 3 barrel on it in 375 Win.
The barrel work was the easy part, getting that dang magazine to feed 3 rounds was a whole different matter.
Things we did in our youth just because.

jeffeossoi saw that done .. iirc, the #1 barrel as a fat taper that will need to be addressed in the stock

dpcdOk, and apologies to RA; I have installed many take off barrels on other actions; for various reasons; they were free, just because, put a lot of 45-70 Ruger barrels on Mosins and #1 Enfields; just to be unique. Like a 95 Steyr Straight pull with a 444 Marlin 336 barrel on it; owner killed a hog with it in Sep.
Anyway, here are the numbers for Ruger barrels; I have all the barrels: of course all are 1x16 thread.
--------------Thread length----Shank OD---Shank Cylinder Length
#1 45-70........ .869............ 1.2............. 1.7
#1 375......... .860............ 1.2..............1.9
#3 45-70....... .843............ 1.16.............1.68
77 30-06....... .686............ 1.16.............1.76
#1. 458......... .860............ 1.2 tapering to .814 muzzle

gwahirA #1 has an extractor cut. Would that hinder?
02 January 2022, 00:59
dpcdNope; you will face off all of it anyway; note that the thread shank of a 77 is .2 inch shorter than a #1. And the extractor cut is only .140 deep. So it will be gone.

Once I find a .458 No 1H barrel with sight/band/rail I’ll PayPal or Venmo you the cost of a case of good beer for that knowledge!

dpcdJust find the rib and base and buy my barrel. You can buy them from Ruger.
I've already done a lot of work for you guys compiling the chart.
