it is said that the norma brass is better. I dont know swampy ive used both norma and wby which are both norma brass and i think overall i actually prefer then remington. Case life has been simular to me but then i dont allways try to squeeze the last fps out of a load. I RARELY load anything over reloading manual recomendations. I have had more problems with things like primer pockets not being cut to the right dept and flasholes drilled off center with the norma made brass. But to be honest id take any of it and use it.
