Looking for a 458 cal bullet for my 4570 for bear and moose
I've got in mind
300 grain barnes
350gr hornady hp
405gr flat point
500 gr jacketed
405-500gr cast (I'm good at casting but not at alloying)
What do you big bore hunters find works best. Ranges will be under 125 yards. I realize all will work but what seems to perform better
 
Baikal mp221 double rifle sxs. Its rated for 28000 CUP.
I'm just getting started into reloading. Its deadly accurate with factory remington 405gr express but recovered bullets have not been of stellar performance and at $60 a box I can't afford to play. The adjustments are very true as I can change point of impact of the barrels by a jack screw. I'd like to try the barnes but something inside says go for the heavies. Just looking for any on game performance reviews
 
Rem. and Speer 400s are known to be "soft" and open well if that's what you're after and should be good for broad side shots. For deep penetration a heavy cast flat point may be more effective, certainly more cost effective.
 
I have a metric buttload of the remmy 405's and 350's (300's?). Both open up really quickly, even at trapdoor velocities. I use them for plinking and gopher shooting (I got them a few years ago, for cheeeeep, less than cast even). They wouldn't be my go-to for big game.

Personally, the Speer 350 hot-cor or Barnes would be my choice

You are obviously handloading; what is your firearm? You NEED a chronograph to properly load for the .45-70, so I hope you've got one.
 
There is little benefit to using a jacketed bullet for North American game in rifles with a muzzle velocity less than 2000 fps. A cast bullet will provide all the accuracy and knockdown you're likely to need.

I was shooting a .45/70 long before inexpensive chronographs became available for riflemen, and I managed to load my 95 Marlin across a wide range of bullet weights and velocities without getting myself into trouble. These instruments are useful and handy, but occasionally their necessity is overstated . . . . sometimes by me.
 
All I ever loaded my Marlin with is 400 gr moly-coated cast bullets and IMR 3031. Accurate, hard hitting load, that lays moose and bear down in a hurry.

The bore never leads up, even at velocities approaching 2000 fps.

.458 diameter bullets

I bet you the Woodleigh 405 grain Weldcore Flat Nose would be a fine choice. They are rated for impact velocities of 1700-2000 fps.
The nice thing about the Woodleighs is thier profile, besides being a highly recommended big game bullet, is that they are very close in outward design, to the Remington 405 SP. And the cannelure position is very close on both as well. The Remingtons have a perfectly flat base, and the Woodleighs have a slightly bevelled edge. A smart fellow would procure a small quantity of both and handload both bullets to an selected handload via experimenting during the off season. If things worked out well, perhaps a larger pile of Remington bullet (bulk bullet purchase) in handloads for practice ammo in the off season would be a good purchase, augmenting the shorter pile of more expensive Woodleigh handloads, for actually hunting these bigger species of game. Burn a limited few Woodleighs for actual confirmation, (and all that summer practice with the cheaper Remingtons is well spent time indeed) just before opening day & I think that's perfect myself!

maybe just an idea........
