.460 S&W reloading question

[Jason Singh]

Hey all,


I have heard that it is possible to resize a bigger bullet into a smaller bullet. I am specifically interested in resizing a .458 size bullet to .452, so I can reload a .460 S&W round. I have 3 questions.

1. I want to resize and use a 500 grain bullet(link below) to reload the .460 S&W, would this be possible? Any data available?

2. I also want to resize and use the 405 grain bullet(below), would this be possible? I have seen data for a 395 grain bullet, would it be safe to use these numbers? or is that .01 in grain weight too much, for it to be safe?

3. Last, I noticed the 350 grain bullet in the .458 diameter is much cheaper than the 350 grain bullet in .452 diameter, would accuracy be affected tremendously using the former?

While you can resize .458 to 452 there is no need to do so

If you want a 405 grain bullet they are available in .452

Bullets larger (and longer) than this will present cartridge length issues for you
when loaded to max length + 2.3" you will have very little room for powder.
When loading at max length if you have any bullet creep and tie up the revolver.

I would suggest a BFR revolver if you really want to shoot extremely heavy bullet - it has a 3" cylinder and will allow you to seat the bullet much shallower.

In the real world once you pass 360 grain bullet in this cartridge you have past the optimal bullet weight- in other words there is no real world value other than bragging rights -

This was done with a 260 grain CPS North Fork , why do you think you need a 405 grain bullet?

Addition information you should know
The twist of the S&W is marginal at best once the bullet length exceeds the length of the 360 grain bullet.

At 100 yards bullet stability is questionably and key holeing observed with

Another reason the BFR is better suited is it 14 to1 twist as compared to the 18 to1 progressive of the Smith offering.

and without which knowing bullets at 350 grain bullets you are referring to the question cannot be answered without guessing.

Typically cast bullets run very close to same cost be weight with out regard to caliber- it is a simple material cost equation.

thing they do influence cost would be gas checks and alloy - GC add to cost as does increase in hardness

Thank you guys!

I've shot very large bullets in the BFR 460 S&W. No comment on twist vs performance for an X-frame. My BFR is a 1 in 16 twist.

Anyways,

My mold is a 425 grain ranchdog mold in .460. I squeeze them down to .452 without issue.

You can take ANY cast bullet for 45/70 and crush it down to .452. I suggest you do this after lube, not before. You will lose some of the lube space. But you gain drive band. That may or may not help you. I find it very helpful.

I have shot many flavors of 500 grain bullet, a 590 grain bullet, and even a 740 grain bullet in 460 S&W. all started life as either 45 cal BPCR bullets, or in the case of the 740, a 458 Lott/460 Weatherby bullet.

I have a box of Corban 400 grain bear bullets. Lot less trouble to buy a box than to reload. Also use 45 log colts to practice with. I love my 460V but kinda heavy to carry when fishing in Alaska!
