Home Forums Hunting & Shooting Express Rifles and Big Bores Only The great 458 Winchester. Everyone should own one at least once

crshelton ol'buddy thanks for the welcome.

To elaborate on your reply to Bugger about the .45-90, yours in an M1886, and his in an M1885 Hi Wall with 28" barrel:

Uncle Bob did a long throated Ruger No. 1 .45-70 Govt. with 2.1" case and equaled the SAAMI-restricted .458 WM ballistics.
He called it the ".45-70 LT."
Bugger could easily do it with his 2.4"-case in the 1886.
I had a reamer made by Dave Manson for the .45-100 Sharps Straight 2.6" that had the SAAMI .458 WM throating tacked onto it.
The Starline brass case itself (.45-2.6") is two grains of water bigger in gross capacity than the WW-Super or Hornady brass for .458 WM.



The .45-100 Sharps Straight 2.6" Winchester Throated (.45-2.6" SWT or .45-100 SWT) will handle any load I can put in the .458 WM 2.5".
COL is just 0.1" longer in the former than the latter.

After I "invented" this I found it had been homologated by CIP about a quarter century ago (IIRC) as the ".45-70 Elko Magnum."
Exactly the same chambering.



Some ammo for the .45-70 LT and .45-100 SWT:



Some rifles for the .45-100 SWT:

Ruger No. 1 with Pedersoli barrel: Add 2.5 pounds of scope and rings (i.e., S&B 4-16x50mm P&M II Mildot in 34mm rings) and it weighs 14 pounds.



Ruger No. 1 .45-70 Govt. re-chambered to .45-70 Elko Magnum aka .45-2.6" SWT, etc.: Add 1.75 pounds of scope and rings and it weighs 9 pounds.



Those two rifles are the upper and lower limits on weights of rifles that I have capable of .458 WM+ ballistics.
I have fired 0.461" diameter cast lead bullets from both with good results, even the tighter Pedersoli barrel.
That is mainly what they are for, cast bullets.
The tighter Pedersoli is good for paper-patched BP loads too, like the Sharps guys might load.

Speaking of the devil, 500gunner sent me some .45-2.6" Starline brass so I got even with him by sending him some 450-gr TSX.
Tit for tat.
