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

And then there is all that new stuff, bunch of ball powders, many touted with temperature stability,
many having copper-fouling-eliminator additives, etc.
All being better at packing a greater weight of powder in a given space,
Especially those with flattened balls or a mix of round and flattened balls.
Any powder good for the .223/5.56 is good for the .458 WinMag.
What's good for General Bull Moose is good for the USA, that kind of thing.

And great news has come from Sir Larry that there is a new Ammo Supplier to compete with Buffalo Bore.
Boy howdy do they !

Aria Ballistic Engineering: "ABE Ammo" is hopefully honest as Abe.
They have a physical address, telephone number and email on contact page.

Using Hammer, CEB, TSX and hardcast/gas-checked bullets that are loaded for the .458 WinMag is of most interest.
Whether they are using a SAAMI MAP or a CIP MAP, well they are a USA maker.
They are also loading same bullets in the .458 Lott at almost .458 WM+ levels.
I think they must have been reading here and at the Hammer Bullets forum.

The 404-gr/.458 Shock Hammer was conceived at this 24hr Campfire thread and birthed at Hammer Bullets in 2022.
I made the first order for those bullets on January 18, 2022, had them in hand six days later.
Already it has taken the world by storm.
No mere component bullet now.
It is in commercially loaded ammo by ABE.
The 404-gr Shock Hammer and CEB 450-gr Safari Solids may not be pictured below,
but can be found in the listings for each cartridge.
This suggests that the website photos were taken before those two were added to the offerings.
CEB Raptors, Hawk bullets, and the ELR bullets by CEB and Hammer may also be found in various cartridge offerrings.
Lots of rifle, handgun and shotgun offerings. Whew !!!

.460 Weatherby Magnum (CIP COL and MAP) 23.5" barrel: 2700 fps/6473 ft-lbs

Once again we see hints at the HORNADY lab data that drove Ross Seyfried insane,
resulting in his "denial" of the .458 Winchester Magnum:
If the .458 WinMag and the .458 Lott are kept to SAAMI standards,
the .458 Lott has only a 50 fps MV advantage over the .458 WinMag with a 500 grain bullet.
2250 fps MV versus 2200 fps MV respectively.
That is with a longer COL and higher chamber pressure for the .458 Lott.
If we allow the .458 WinMag same COL and MAP as the .458 Lott it
becomes the .458 WM+ and leaves the .458 Lott far behind in its dust.
(Where is the kissmyazz emoji when you need one ?)

In the ABE example here, the .458 Lott got a half-inch longer barrel,
and the results were the same MV difference, only 50 fps.
This suggests that the .458 Lott advantage over the .458 WinMag is miniscule, at SAAMI standards restrictions,
and it decreases as bullet weight decreases.
This is something that we have long know in regards to comparing the .375 Weatherby Magnum to the .375 H&H, etc.
Heh-heh-heh.
