Hello all, Got a quick question before I actually load my first 10mm rounds. I have the turret mounted and got the dies set to produce 1.26 OAL 180 gr rounds. I just finished double and triple checking my powder drop from the Lee Auto Disk for 5.4-5.5 gr Titegroup powder and I think everything is ready to go except....I pull out my brand new Starline brass and maybe have a dumb question. With new brass do you need to put it thru the sizing die/ decap? I know it doesn't need the old primer removed but didn't know if I need to make sure and true the brass. Also, do you need any type of lube if using the Lee carbide dies? I read that some say no lube needed but then others say yes. All the info is appreciated. Wanna kill these ads? We can help!
