I'm 67, got my first 7mm Rem Mag in 1973 ( a Browning BAR) have owned/used several through the years. I remember an article by Col Askins who took one of the first ones Brown Bear hunting. He used the 175 factory load. He said he wondered why Remington hadn't offered it with a 160 "as everyone knows the 7mm caliber balances better with the 160 grain". Something like that. Anyhow, there were lots of great articles when it came out, wonderful for a poor 'rifle Looney in the Making", ha.
