[QUOTE="Bart B, post: 632937, member: 5302"] 120's from a 7mm Rem Mag leaving at 4000 fps? Max loads for 120's from that case leave at about 3300 fps at max safe SAAMI spec pressures. Not only will you get a very short barrel life, you may well shorten your own. Your case life will also be shortened to perhaps 2 loads per case. [/QUOTE]
