The 300WSM is what it is.It's a short action 30cal.Loaded on the milder side,it's like a hot loaded 30-06.Loaded on the hotter side,it's like a moderately loaded 300 Win Mag.It's an in betweener and will cover most hunting needs.I have rifles in all three of those cartridges.For nearly all my hunting,the 30-06 has me covered.If I feel like I need a little more for distance or bigger game,the 300's do have an edge.As for economics,the 30-06 beats them all.
Very true. It's a lot closer to the 300 WM than it is to the 30-06 but you can load it for anywhere in the gap that you like.
