Gary, after being on the fire i have a great fear that not only do people not read books ,but their reading comprehension is non exsistant.

Op. Swaging will demand more then your normal press will afford you. I have swaged 458's to 454 and 452. It way as stated , a beast of an effort to do very many.
That said i did get a lee push through and rigged up a mount on my wood splitter to do it . Slow but effortless.
It is possible one could go in steps of reduction and do any desired.
I havent forgotten the promise of 45-70 data. I am having a bad MS day and havent made it upstairs to my gunroom. Will get that for you.
PS would love to see pictures of that FN 45-70. Rare conversion.

the consolidation of the states into one vast republic, sure to be aggressive abroad and despotic at home, will be the certain precursor of that ruin which has overwhelmed all those that have preceded. Robert E Lee
