I too used mixed brass when reloading Berry's 124gr RN with 5.5g of PowerPistol, also with an OAL 1.160, which is the OAL specified by Berry's for the 124gr RN. I use the Hornady 3 die set, however, I only seat the bullet with the Hornady seat & crimp die, then I run each round thru a Lee Factory Crimp die, which applies a slight crimp and applies another slight resizing of the case. I also sometimes have completed rounds that show the slight bulge around the upper case area where the bullet is seated, this is most visible on substandard soft brass cases, such as Blazer and several others. After running all rounds thru the Lee Factory Crimp die, they all pass testing thru the 9mm gage.

I haven't had any issues using Berry's OAL of 1.160 with the 124gr RN, which I use in 3 different 9mm handguns.

Berry's does list an OAL of 1.130 for their 115gr RN plated bullets.

I reload 357 mag, 9mm, 44 mag and 45ACP and use the Lee Factory Crimp die for each caliber, I think it works great!
