The only difference between Lapua and Norma are the flash holes! Both are the best of the best. Lapua punch the flash holes and Norma drill out the flash holes! I shoot Lapua when I can get them in a particular cartridge and shoot Norma or RWS on everything else. If you have Lapua, deburr the flash holes and you are good to go. Norma cases do not require deburring.
