When I hunt deer in the fall I carry a side arm,I curious as to the heaviest 357 load I could carry in my 640-1 357 that would be effective should I need it.
First place to look is your state hunting regs and see if they specify ammo/handguns legal for hunting. In my state (OK) that gun would not be legal to fire at deer, although it could be carried for personal protection while hunting.
Secondly, if it is legal under the hunting regs, I would use a good 158gr for penetration. Even with a long barrel, .357 is on the light side for deer hunting, although I do use it for our 100# does.
.I don't plan on this being my main weapon,I hunt with a Russian MN 91/59 in 762.54R using a 200gr bullet
A solid copper bullet will likely be longer, use more case capacity and leave less room for the powder. I'll SWAG that the velocity is less. Then again, I could be absolutely wrong.I just recently chronographed some (sadly discontinued) Federal 140 jhps out of a 640-1 and got an average velocity of 1135fps. I suspect that their Vital Shok Ammunition P357XB1 with the 140 grain Barnes copper hollow point might give similar velocity but better weight retention and penetration.
Would the Winchester 145gr Silvertips be better than the Federal 158gr semi-jacketed HP's.I have a partial box of the Federal,don't shoot them that much as it's a real handfull from the 640-1.I wouldn't carry too heavy a bullet in that M640 because it's such a light gun. I would probably carry no heavier than a 158gr bullet but probably would carry a 145gr Winchester Silvertip in a M640. When I carry a .357 Magnum as a backup in the woods I carry a 4" M686 loaded with ammo loaded with a 180gr Hard Cast bullet.
