Forming from 6.5G with Mighty Armory die
#7
I've got 200 pieces of Starline formed thus far and using this die is like sizing butter. Far easier than the many pieces of 6.5G Hornady brass that I formed into 243 LBC using a Redding 6.5g bushing die (which didn't involve a 0.03" shoulder bump) and also the 400 of Nickel plated Starline that I formed into 6 arc using a Hornady 6 arc die. In both those cases, I used the RCBS lube you use on a pad and used a cotton swab to apply it to the brass shoulder and the inside of the neck

I've been almost exclusively using a mix of standard 100% lanolin and 99% isopropyl as a lube since the scamdemic started. I think its a 10/90 mix - I honestly forget and go by the markings I have on my spray bottle when I fill it. I gave that a try before changing to what Mighty Armory recommends (including the pricier PEG 75 lanolin) and it works just fine (as well as costing less than 20% of the Hornady spray lube!). I also didn't bother to let it dry for 30 minutes like Mighty Armory suggests - I just sized like I always do by wiping the shoulder and neck with a rag wrapped around my hand prior to putting the brass into the press to prevent hydraulic sizing. Results were perfect and I didn't crush a single piece of brass nor did I get any dimpling on the shoulder. I'll note that after sizing, I do run it in a tumbler with corn cob media (or a mix of corn cob and rice) to remove excess lube. That also leaves primer pockets clean with fired brass, although some do need to get quickly run through a decapping die to remove media that may get stuck.
