Animal,
I have a 35 Whelen Improved, but not in a TC, its a 1917 action. Accuracy at 100 yrds with 250grain is excellent, if I do my part I can get them to cloverleaf. Kick, not a sharp kick like a 300 mag, more like a 12 ga shove. I do have one of the soft recoil pads and its in a ploymer stock. The Improved version helps provides a sharper shoulder and longer neck. I am used to a rem 700 in 06 and I will take the Whelen over the 06 with 200 grain any day. Keep in mind, my 1917 action is heavy, last time I put rifle and scope on a scale it came in at 7.5 lbs. Performance, I think you will love it. Kick, that seems to be a what you have been used to. From 270 to 35 Whelen, you will notice it. From 06 to Whelen, not so much....I say go for it.
