I also find it odd that the 125 grain 357 magnum load that earned the reputation was a semi-jacketed bullet. But Most of the 357 sig rounds I find have little or no exposed lead.
When I originally bought my Glock 33 I thought that I could use my stock pile of 357 caliber bullets to reload the sig. Unfortunately I was wrong. I wish they would have named it the 355 sig. I know I should have done more homework.
Always looking for a good hunt!
