Hello all, my first post here. After snooping around the web and such I am puzzled as to why more folks are not using the 7mm SAUM. With the addition of Norma brass in 300 SAUM available and concidering that the cartridge is much more efficient than it's Win. counterpart, with very little difference in velocity. This question came up after a phone call from my pops. He decided he would head out to Colorado to join me for an elk hunt before he is not able. He is sneaking up on 75 years of age and I want to steer him towards something he will be able to shoot for a few years. Any thoughts?
