Just pick up a Dillon 550B for reloading 338 Lapua Magnum only. I already got the conversion kit. I have the standard powder measure. Just want to double check. I believe I need to order the X-large power die ($19.95) and order the magnum rifle powder bar ($29.95), however, powder bar only goes up to 85 grain. Or should I just order the Magnum powder measure ($137.95). Price is adding up, I'm starting to think I should just manually measure.
