sizing bullets

[dgr416]

I have a 333 okh belted mag rifle that I want to size some 338 bullets for .I talked to redding at the NRA show they said if I sized them down twice I.could do it with a regular reloading.press instead of having.to buy an expensive H press and buy one .I am not sure what kind or size sizer to buy .You have to make a ram to push them through the die .I.wish I.knew someone who know how to do this .I know that you can't use bonded bullets but you.can use partitions and regular bullets .I.want to do about a 1000 that should last a lifetime for me !

I have not sized jacketed bullets.

Corbin swaging has said sizing down more than .005" may leave a lead core loose inside the jacket?

This is because lead does not spring back, after sizing , as much as copper jackets.

It's not a good idea but some seem to get away with it . A lot depends on the kind of bullet you want to size down. Core bonded should hold the jacket grip if not sizing too much a bigger cal in a nice tight bore might work ok also.
Monolithic bullets can be sized but it takes more power .
A partition type bullet may suffer less .
There is so many variables it's nearly impossible to say when someone just says "bullet " What kind of bullet construction exactly ?
