I would suggest you find friends with rifles in the calibers you like and shoot both... Many years ago, a friend was making the same choice.. I have both in similar wt. rifles, and I let him shoot both.. He went with the 7mm.. I prefer the .300, but he was not a shooter and reloader.. He would buy a couple bx. of ammo and use that.. It worked out fine.. Both are top of the line for 95 percent of the game we shoot..
