Danm. Good advice all round. I just looked at the Sierra rifle reloading manual's ballistic tables. If your lowest setting is 200 meters, (about 220 yards, roughly speaking) then the 2 inch high impact at 100 yards is just about on the money. At 2700 FPS, the Sierra manual showa a mid range trajectory for a 150 gr. bullet to be 2.17 inches high. If the grouping is within reason otherwise, you are doing OK.
By the way, you don't need to lube with the RCBS neck sizing die. I don't. Only the full length dies need lubing.
