I Have a older Lee single Cav hollow point mold it drops an nice 147-148gr at .360"





Obviously I will swag them down to 358 for 38spl and 357mag.



But Can I swag to to .356 for a 9mm??? And do it safe?



Thanks

It's going to be hard to swage them down 0.004".  Hope you are strong and the press is big.    You could try doing it in two passes though, one to .358 and then another die to .356.

According to Corbin, you can swage even jacketed bullets as much as .006" in a press.

You can size them down .004" very easily. Lead is very soft even as hard alloy and sizes without much effort.   Lee make a economical sizing die that goes right on your press and there are dedicated sizer/lubers that RCBS, Lyman and others make.

The only problem you may experience is that sizing more than a couple of thousandths may affect the inherent accuracy of the bullets.  Most shoot best when closest to as cast dimensions.

Swaging = going up in size
Sizing = going down in size

I'm not trying to be the grammar police, but it is "swage" not "swag." When talking about a technical subject it is helpful to use the correct terms. In saying that, my post above highlighted the fact that you increase the diameter when you swage and decrease the diameter when you size. What you are seeking help on is bullet sizing rather than bullet swaging.

No problem, I have used the term Swage/swaging when cold forming metals.





The general concess is that yes it can be done safly, but it may not be the most accurate thing I could do??

Probably easier to get a correct diameter 6 cavity Lee mold.

That's what I would do.

You would be amazed how fast the bullets pile up with a 6 cavity mold.

You can go from .360 to .356 but its work
You can go to .358 first, then .356. That is easy. I've done it to make heavy boolits for my 9mm. They didn't cycle well anyway.
YMMV
