Get the Lee manual. It gives instructions written for the equipment you have. It also has load data from several sources. Some of what you get off the internet may not be exactly correct, so take any info you get with a grain? Pacesetter dies are equal in quality to any other dies, they're for bottleneck rifle cases and require the use of case lube. Carbide dies are generally for straight walled pistol/revolver calibers and don't require case lube. You aren't likely to find many 6.8 or any other carbide rifle dies. Most straight walled pistol type cartridges require case expansion after sizing. Pistol die sets will ship with them. If you have another brand you can buy just the neck expander from Lee or whomever based on your needs. A taper crimp is used for most selfloading pistol cartridges, heavy recoiling revolvers will need a heavy roll crimp. Read, read, read! Also check out the manufactures website. Always dig for answers, ask lots of questions, and "when in doubt don't" Good Luck, welcome to handloading!
