I like the .458s but i would avoid the Barnes 300gr Triple Shock (with the small hp) and the 300gr Original at sub speeds. They work ok in a hot Savage load but need more fps than subs can provide for reliable expansion. The 300gr SOCOM or the 300gr TSX FN with the big hollow point do fine at 45/70 and ML speeds.

Ive shot many Barnes Originals and the high BC is worthless up close and once it is of value, the speed has fallen well below what it needs to expand. If you can achieve atleast 2100fps MV things change a bit but its still a very tough bullet.

yes I remember now. The original is a savage bullet due to the speeds it can reach, randy wakemans bullet of choice. I was thinking the .458 275 bloodline may need that extra push too, or not. basically what your saying is stay w/ 45/70 speeds and that will be in the omega's speed range. 1900 is a good place to be w/ around 110 grains blackhorn. 290 TEZ, 285 MZ Spitfire may be a good choice too. I think sierra may have some good stuff as well.

Yep

Common 45/70 load data and 50cal MLs can produce similar velocities. The Savage can easily exceed a 45/70 except for maybe Ruger #1 load data. The 458-325gr FTX is a good choice if you want a higher BC and still get reliable expansion down to about 1300fps.

Retained about 250gr

It will rock you a little bit too though.

I am ordering the .458 300 remington and give that a shot. The omega has the thumbhole laminate, heavy but accurate and i have been impressed w/ the new redfield on top. It's really a nice set up.

The 458-300gr Rems and Sierras are both good bullets. They don't cost a fortune either.

.458 300 deep curl

Doesn't exist.

unicor 300 .458, I will just stay w/ speer because I can not only afford to shoot speer but also you cant go wrong w/ the make up of this projectile. .452,.458 300 for the bigger stuff and the .452 250 for the deer around here is plenty.

South Dakota, what is the hunting like there. I am thinking big elk, deer, moose and grizzly? possibly moutain lion. Vermont is very boring unless you travel 4 hours into maine or get up around the canadian border. South Dakota I am thinking one could get killed.

Here is a link to the construction of a few .458s

Notice how thick the plating is on the Speer. I will post the cross section pic of the bullets when i can find it. New Barnes Originals 300gr Spitzers are actually .035.

A thick jacket can be a benefit but sometimes they can be less accurate too. A lot depends on the jacket material and lead purity. Thinner jackets and a pure lead cores are often very accurate and very effective on game if they have enough mass.

I haven't shot the Speer 458 but i can tell you the Rems, Hornadys and Sierras are far more popular than the Speer 458s.....At least with Savage owners shooting under 200 yards. It might be the concave base hurts accuracy at those speeds.
