I used to try and fill caliber gaps in my arsenal, but now I am trying to fill Bullet Grain gaps.. For example.. I have a 243 and a 7mm-08 they but I can't get a 243 with a 140 grain bullet.. So I got the 7mm-08.. But I also have a 35 Wheelen and I do like it, but since you have an 06 and can overlap the bullet weights with the 35 I would opt for a different round just to be a little different.
