I'll all ways choose 7mm over 300 any day. Why. It's because I've shot both. 168grn to 230grn from the 300 win mag and 300 Norma mag. 140grn - 180grns from the old tried and true 7mm mag. I have all ways been more accurate with the 7mag. In my 30 plus years of shooting I have come to realize if you can't hit it you can't kill it. I may live in Texas but I don't believe bigger is better. So tired of my truck is bigger than yours thang. My motor is bigger. I have a bigger gun. I still get the same reaction from people when they tell me they are Marine Scout Sniper, Navy Seal sniper, Army Ranger Sniper. If they are who they say they are than they should be able to out shoot me any day of the week. My best group was with my 260 Rem 140grn Berger. 4 shot group 3.5" 1760yards. And yes I am proud of it and nobody can take it away from me.
