Im currently deployed in Afghanistan and have a NEMO Omen waiting on me when I get home. I looking for someone who has done some leg work with bullets/powder combinations for the 22" barrel they make. I reload for M14/AR-10/556, but never messed with mag reloaders. Looking for any nitchs or bullets/powder combos to be concerned about. Bullets I currently have are 175gr SMK, 175 gr LRX, 200 gr SMK, 220 gr SMK, 230 gr Berger Hybrid Tactical, and 220 gr Lapua Scenar-l's. Powders range from H1000, Hybrid 100v, IMR 4831, Varget, IMR 4064. Im pretty sure varget, 4831, 4064 are out of question. Anyone have any success for 900m plus loads?
