squishing down jacketed bullets for 10mm

pelo801 · November 12, 2011, 12:12 AM

On one of the local classified ads today, I found a lyman 3 die set for .357, speer 100 count of 220 gr .41 cal bullets, speer 100 count of 200 gr .41 cal bullets, and hornady 58 count of 210 gr .41 cal bullets all for $40. All jacketed bullets. He also threw in half a box of .357 ammo. I've been wanting another set of dies so I don't have to use the same set for .357 and .38. My plan was to use some of these bullets for my .41 ae. But I was thinking I might be able to squish down some of these for 10mm. Does anyone have any experience with squishing down jacketed bullets? With what type of results? And, has anyone used something as heavy as the 220 gr in the 10mm? And while I am at it, the 357 ammo is 158 gr lead HP. The brand is Geco. I've never heard of it. Does anyone know anything about this ammo?

I'm not going to say it can't be done--I do it with lead all the time. The problem you may run into is the possibility of the core becoming loose inside the jacket. Brass and copper have a slight rebound effect where lead does not. BUT, only dropping from .410 to .401 you'll probably come out good. It's not something you want to do on a light-duty press though. squeezing .009 doesn't seem like much, but you're going to be leaning on the handle a little.

I have a lyman 4500 lubrisizer. I didn't mention this before, but the bullets are jacketed soft points and jacketed lead hollow points. The lead is exposed at the tip of the bullet. Not sure if that makes a difference. So I am asking, does it? Will that make it better? I have done it with lead cast .41 cal down in my .401 size die already. Just not with any jacketed bullets. I am wondering if I will damage the dies, etc.

It is likely that the linkage of the sizer could be damaged. I keep grade eight bolts for mine because I have had one of the factory bolts wear-out and break, and have had one of my replacement bolts break also. That was just using the Lube/sizer as it was intended...to size cast bullets. The lube/sizer was never intended to be a swagging press. I would look at the price of a new one before trying to use it like you suggest. Can you afford a new one?
