Norma will be the closest to Lapua but it is not the same. the next best option will be ADG. yes Norma made the Lapua but to a different case head hardness and it will out last anything else that I compared it to. I just tossed a lot of 50 Lapua cases that had 25 reloads on them
Well, I've took Norma to probably 80k+, almost 80grns of RL25 under a 230 Berger doing a pressure ladder, and never lost a pocket. Bertram will be the strongest, but I agree that ADG is good stuff, so is RWS.
