Iused LLA for years before I got a luber/sizer & liked it. Only had problems with leading in 9mm, other cal. like .38 sp, 45 ACP and others did alright. My only other complaint was excess lube on the end of the bullet would collect on the seating die and if not cleaned out would seat the bullet deeper into the case. Really not an issue if you're watching what you do just an aggravation. Never could figger out why I had a problem with 9mm.
