Both the 300 win mag and the 35 whelen are great guns however each one truly fills a bit different nitch. The 300 mag is at its best sporting a 26 inch barrel and is a true performer for long range shooting............something the whelen doesn't do well. However....if your like me and prefer a short handy little rifle for packing on your horse and you prefer your barrel not be dragging the ground the whelen is a true performer with a 20" barrel. My 225 gr barnes handloads are cronographed at 2806 from a 20" barrel with minimal muzzleblast........something the 300 doesn't do well. There truly is a place for both of these awesome calibers and I would highly recommend both of them.
