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

Absolutely agree.
It for sure will have Zero effect on my intended “long range” of 250 yards.

I have not been curious enough to weigh my 350 grain TSX 416’s. I would think there would be more variations than the Hammers. But, they group impressively at 100 meters out of 3 different rifles and several various boxes and lot numbers.

Lol, I almost weighed some 458, 450 TSX. Because I had an open box of them by the scales. But, was not that curious.

As I discovered at the B&M Forum, Sir Larry and Sir John are working on getting Michael McCourry
at the McCourry Institute of Ballistics in South Carolina
to test the 400-g/.458-cal/3mm-HP Shock Hammer for penetration in artificial media.
With the vast amount of testing previously done by Doc M at MIB for comparison,
that will be useful information.

Buy a donkey to those MEN OF THE SQUARE TABLE.
That was mighty Knight of them.

Sir Charles,

The MIB test media of the past has been a form of wetpack, news print and magazines and such,
sometimes with concrete blocks or bones and whatever thrown in,
50-yard indoor laboratory with instruments capable of pressure testing, etc.
Will get updated.

Sir John,
The new Shock Hammer: BEST ALL AROUND
Yes.
May not be the best for a specific ballistic performance item like deepest penetration on blue whales
but it will come closest to being best "all around."

If anyone wants to see it the 400 grain Hammer 400 will pass our ele brain shot test. send me a couple of spare bullets and I will test them when the sleet and snow ceases. I will report confidentially if they splatter on the steel plate.
Some copper bullets from my .405 WCF have done just that, making little flat pieces suitable for hand made bracelets.

Sir Larry,

80 grains of AA-2230 is my favorite for a COL around 3.4" with 400-gr bullets, whether GSC HV or Woodleigh PPSN.
Normal practices: Start at 72.0 gr, work up to 80.0 grains for SAAMI standard loads with 400-grainer.
AA-2460 will also do about same at same charges.
H322 at slightly lower charges.
H4895 at higher charge weights with compression.

All those powders are temperature insensitive and good choices for 400-grainers,
AA-2230 is top pick for me.

Great work as always Sir Ron of Ol Kentucky. I won't be much help to the 400 Hammer cause other than to say I do believe you are on the right track to get to where you designed you wanted to to. That will be as close to "One bullet for all" as one bullet can be. Of course this "One bullet" is being launched by the One True 458 WM the Magnificent which makes any bullet just a little bit better.
Side thought as a question; How does bullet against Steel tests show us how bullet on Elephant heads work? I have never thought steel showed us much about bullets except how that bullet works on that steel so eager to learn.
