Dillon 550B, hands down, is the most versatile press ever designed. The LnLoad is auto indexing, which is great, except for the fact auto indexing does absolutely nothing to speed up reloading without a case feeder.
The 550B, with it's interchangeable toolheads, is the most hassle free press ever designed. With a few tweaks from Uniquetek, it'll loaded match-grade ammo for a rifle, or crank out an active IDPA shooter's pistol ammo needs.
