looking to rent one if anybody has one

Do you want a 5.6x52 and a 5.6x57 reamer; two reamers?

ihave to send it to a machinist so i probably should stick to the real thing can buy one but it's 235 which make a 1 use thing out the door

Ok, I am confused now, which never happens.
First of your posts; I want a 5.6x52 Mag. Second, I want a 5.6x57.
Which do you actually want?
And what is it? I have not heard of every cartridge made, but damn near it. Must have missed one.

5.6x50rmag its a euoopeaan copy to duplicate the 222 mag but has a rim nice for those single martini lunches

Ok, but you said you wanted a 52 and a 57. Not a 50. The 50, I know what that is.

Knew this sounded familiar. Hornady Manual #9 has data.

For the 50mm, 52mm, or 57mm? OP asked for all 3 versions.

Hornady Manual #9 has data for the 5.6X50mm Magnum, 5.6X52mm (.22 Savage High Power) and the 5.6x57mm RWS

The 5.6x57 reminds me of the 224 Clark I had at one time.
