45-70 converted to 458win mag

[jrkrk]

I read this somewhere where a 45-70 encore barrel can easily be converted to a 458 win mag. You guys have any suggestions on who is doing barrel conversions and would the encore frame be strong enough to handle a 458.  I do reload so  I can eventually work my way up to max loads.   Thanx  John

With the 45/70 rim the case head won't be supported at the very end. Don't really now how much of a safety issue that is but it would concern me. Other than that I don't see why it wouldnt work. But why not sell the 45/70 and order a bull custom shop barrel? Seems you would probably be looking at about the same cost difference any way.   KN

Well I spoke too soon. I don't see it listed on the custom shop web page. Maybe SSK could do it.  KN

Thanks KN I called SSK and they can do a blued tapered bull barrel in 458 win mag for $  ;)480.00

I have a 458 WinMag barrel from Bullberry.

They suggest reduced loads (= reduced pressure).

They also make the 458 X 2".  This looks like a modern 45-70 to me.

You could have a 45-70 barrel punched out to 45/90 if you want a little more zing.

Before you go through the trouble, you might want to shoot it as a 45-70 to check the recoil level.  I had a 45-70 Encore with a 24" barrel with a synthetic stocks that will pound you when fed heavy 45-70 loads. Seven shots was all it took to break the synthetic forend and pull the screws out of the barrel. The nice folks at T/C replaced the barrel and forend, and I added some weight to rig by going to walnut stocks and swore off using Ruger #1 loads in it. Bottom line, a 6lb. 45-70 with heavy loads makes my 8.5 lb 375 H&H seem like a pop gun.
