While I wasn't a big fan of lead bullets, after having to clean the lead out of the barrel after those 7 rounds I tried from BBGun, I just took a look through the barrel after 4 rounds of these and all I see is powder residue.
I'll check again after another 20 rounds or so.
My first batch of 50.

That is one of my favorite loads in 9mm LRN 124-125 gr bullet as well as the same O.A.L. that you have. I get mine though a couple thousand at a time from either Quality Cast or Friendswood Bullets on line. Done a few orders over the years and always been pleased. I actually picked up a 1000 125 gr L-FN to try out also in 9mm which is the same load and O.A.L also.I loaded up 4 to try.
4.0gr. HP-38 and OAL 1.130"
Test fired fine, cycled fine.
Yes, I searched for a load for 125gr LRN.
Yeah, the box says 124gr, but I random sampled them and they are 125gr. +-.2gr.
