If you want a comparable
round then yes. Some people just don't wish to LEARN or THINK. Guys not everyone is a master word smith like you.
The 338 edge will get you in the area of the 338 Laupa. People call the edge the poor mans Laupa.
338 Edge - History and Development
The edge is just a 300 RUM necked up to 338. The draw back is that it is a wildcat and you would have to have your rifle rechambered or rebarreled into it then you have to reload your own ammo.
I have a buddy that built one on a Remmy 700 RUM action he dropped it into a McMillan A4 stock and topped it with a 5-25x56mm Nightforce. It shoots great out to 1000 yards.
