Glad to see my old post getting some use!!
I also have the Lee 105 (drops about 112g) and the 125 RNFP (drops at about 130) both for a hodge podge alloy. I've only used both in .38 spl. That 125g should be nice at 7g of unique. That little 105-swc is my FAVORITE .38 spl bullet over small loads of bullseye, tack driver.
Good luck and let us know how it goes.
