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

Hello Fury, got the 220gr Hornady solids in tonight's mail, many Thanks Sir, i loaded a test load with 65gr H-4831, will adjust powder charge on workup so they land with the 220gr partitions at 100 yards through the receiver sight, because of your generous gift, i have decided to take the old 300 H&H for plains game, little Wife volunteered to carry it so i can carry the scoped 458 WM+, a quick hand off as situations dictate will get it all handled, i expect these old Hornady solids to perform just fine, just like the old factory loaded 458 WM 500gr solids Sir Tony sent Sir Ron.

I sent some pics to Sir Ron, said he'd post em up for us tonight.

Thanks again Sir, Best to You and Yours,

Gunner

rock on gunner man👍👍👍😃

"Guns of gunner500" is a gunporn series with redeeming social value.
Here is the latest installment: .300 H&H Pre-'64 Winchester M70









She is well preserved considering her age.
Sir Jerry may wish to make some gentlemanly comments about the fancy lady.

I ain't got the class of gunner500, but bear with me, we'll relate this back to the .458 WinMag eventually.
I bought a .300 H&H Pre-'64 from a gunshop in Tallahassee, FL in 1990.
Walt Sherman was a local gunsmith who re-barreled it to .375 H&H for me by 1991,
with a Douglas stainless No. 3 sporter of 1:12" twist, left it in the walnut stock.
It went to Alaska in 1992, kilt mah furst bar with that rifle.
Had it put into a Brown Pounder stock and it went to Botswana in 2001.
Kilt mah furst African plains game all with that rifle too.
Then something came over me sometime after 2006 and I got a bee in my bonnet about my very own rifle caliber,
the Three-Nine-Five. Five different wildcat cartridges exist of that caliber, that I know of,
and I am to blame for all of them.
The .395 H&H was the last of the five, believe it or not, on that Pre-'64 M70 .300 H&H action.







I jumped the shark with that one.
My 3.6" stroker pair could just as well be a .395 H&H and a .458 WM+.

.358-cal bullets with near identical ballistic coeficient to the 404-gr/.458 Shock Hammer:

Speer 250-gr/.358 SP Hot-Cor, G1-BC = 0.422

Nosler 225-gr/.358 Partition, G1-BC = 0.421

Load down to 2500-2600 fps MV with either of these:

Sir Jerry,

Since you are getting back to Africa before me, it would be magnanimous of you to use the 404-gr Shock Hammer on a cape buffalo.
Couldn't happen to a nicer guy.
For science !
I can spare 3 boxes.
Start with 81.0 grains of AA-2460 and use a drop tube, and COL of 3.480", W-W brass and F-215 primer.
That might even be better than my AA-2230 loads.
To be reviewed here while you are waiting to get the bullets.

I'll sleep easier tonight Gunner knowing the old faithful girl is being carried afield on the Dark Continent with a solid in reserve.

Thanks 44 old Buddy, will do.

Yessir Sir Ron, will be glad to hunt my tail off looking for a big bull to bust with the 400gr Hammers, i greatly appreciate the gift as well, will start at 81gr 2460, will be looking for an accurate 2500-2550 fps, ten four on the 3.480" COL, also Thanks for posting the pics of the old 300 H&H, it's a great rifle and one of my favorites, it does indeed need to go for some plains game, will be looking forward to your review with the 2230.

LOL, Thanks again Fury, i loaded up to 68.5gr H-4831 under those 220gr solids you sent me, they crossed the chrono at 2699 fps, man that's going to be a major hole driller, i'll shoot them side by side with the 220gr npt's and see where they land.

On the burn rate chart that I'm looking at it is 2230 and then 2460. They are side by side, must be very simular burn rate

Yes, Sir Ron says about half the granules of the 2230 are slightly flattened somewhat altering burn rates between the two powders, i look at both as being slow burners for straight walled 458 WM+.

Prior to 2016 - when 2230 and 2460 were "reborn", I tested those powders along with H335 and H4895 (plus a few others). 2230 was significantly faster than H335 which was very close to 2460. Two grains more of 2460 gave nearly identical results of H335 from my tests shooting the 500gr Hornady in a CZ 550 (25" barrel).

My current understanding is that both the reformulated 2230 and 2460 are now made in the same plant in St Marks, Fl as H335. It's the only plant in N.A. that makes ball powders. I know as a fact, that for several years H335 made in the St Marks plant is significantly different from the "old" H335 that some complained about as "dirty" and not temp resistant. See Hornady on that powder for both the .458 Win and Lott.

I've used H335 in several .45-70s and in the CZ 550 in .458, and now my Ruger #1H, and it is, if not the best, then certainly one of the best! Not dirty nor unstable with changes in temps from summer to winter.

Since TAC and H335 have near identical burn rates, and since TAC has proven its worth in today's .35 Whelen, I intend to give H335 a try in my new .35 Whelen. It's burn rate is similar to H4895, which is stellar in both the .35 Whelen and .458 Win Mag.

And, Sir Jerry, I, too, am greatly interested in your African hunt, wishing you God's best and great success!

404 grain Hammer bullet by by Riflecrank's insistence. Interarms MarkX.
81 grains 2230 heavily compressed with bullet seated to fit magazine at 3.310"

That will work for sure.

Probabaly a 600mm/23.6" barrel on the Whitworth.
Here is a 25" Shilen that is about average for barrel speed:

Same net case capacity for the two carts shown above.

For Sir Jerry:

Thanks for the powder history enlightenment lesson Sir Bob, i have used H-335 in sammi spec'd 458 WM for more than 30 years, have a giant bag of 500gr partitions loaded up, they run 2160 from an old FN Browning Safari with 24" barrel, i need to get that setup to Africa after this trip, Thanks for the well wishes too Sir, it's going to be a great hunt, especially learning what Sir Rons brainchild of a bullet in the 400gr Hammer does to buffalo, i'll be looking for an accurate 2500+ fps with 2460 powder.

Damn good shooting with the 2230/Hammer combo Sir Ron, and Thanks for posting the pic, i'll send proof i've had my old 300 H&H and Africa on my mind for 20 years! it coupled with the 458 WM+ is a fine combination.
