Smokeless Resizing Hornaday 4500 .458 to .452

That's a big step down, will need stages or a huge press weight.

Try running the SSTs through several times, each time you should get a little less spring back up to a point anyway.

Very interested to follow your results. Keep us posted.

I know this gentleman was ill a while back but it might be worth a shot to give him a call to see if he can make you a sizer. $25 is a good deal.

CR500 I always wanted to do this to the BO as the BO was and is my all time favorite .458 bullet. It has the thickest jacket of all of the .458s and there should be no spring back. I would love to see the results of this one!

Indeed sir that is pretty cool. I believe my stalker is close to .452. Looking forward to results.

Try 10/50 IMR-SR4759/IMR4198 if you can find the SR4759.

Lights out accuracy and temp stable.

Sorry, that's for 250s. Don't have a load for 300s.

I only use the IMR SR4759, not familiar with the "plain" 4759.
