Yes I realize there is a 7mm-08 Light magnum and the .308 light magnum still outperforms it....by a slight margin.
More offerings does make the .308 better if even one of those offerings outperform the 7mm-08...which they do
So just which 308win light magnum load shoots flatter than the 139gr sst light magnumload for the 7mm-08?
The two 150gr light magnum loadslistedfor the 308win can't match it and neither can the 165gr light magnum load listed for the 308win.
If you are talking energy,the 308win starts out with slightly more,but the 7mm-08 catches and surpasses the 308win.
I don't remember making a case for the .308 shooting flatter. But less than 1" is negligable.
the 165 grain SST .308 has more energy and there is less than 1" difference in trajectory. I've only been comparing out to 300 yards as that is about the max effective distance for those rounds on elk sized game IMO. Also I don't know that the average hunter shoots beyond 300 yards. I personally don't think so.
The load I use has over 1900 ft/lbs of retained energy at 300 yards and only drops 8.1.
I mean I don't know if you realize this but my point is: If you can get as good or better performance with a heavier bullet, plus have more bullet choices, and cheaper ammo why wouldn't you?
