[QUOTE="DANTEC, post: 31785, member: 685"] ok if you go with Nammo CAREFULLY check CIP drawing because a very commum way is to make BROAD chamber with DEEP throat "à la CIP" to keep pressure LOW and as 6.5/284 Norma you need or must need to use Norma match ( in fact a wilcat ) to get something that work as a target rifle and not a hunting look a like target rifle . pressure : if your performance are get from family case 6 PPC that not possible for CIP to use same or highter pressure than parent case ( seely but CIP rule ) so if your performance are get at 6 PPC or hotter pressure , your CIP cartridge will be lower in performance . check too if CIP load works in semi auto ( smooth operating ) because match pressure ( CIP rules ) are just pressure peak and not all loading works fine in semi auto and specialy in AR15 ( ratio port location / pick of pressure ) OAL : CIP aol need to be check to match with bullet deph seating ( short OAL with long bullet = poor cartridge ) with time and several trials Lapua ( Nammo ) velocity are low to very low to get mild pressure I have never understand how they can reach so highter pressure with not heavy load . good shooting DAN TEC [/QUOTE]
