T3 is an excellent choice. The ones I have been around didn't have any shooting problems. Not much negative is associated with the T3. If the T3 fits and feel right is all that matters.

3006 vs 308 both established rounds that will always be in style. The 06' in my opinion is a better choice if you will be hunting larger then deer game regularily, based on its ability to handle/utilize the larger gr sized bullets in the .308 cal.06 produces more velocity which inturn boost energy and ballistical numbers. The 06' has more recoil. OTC ammo is no problem with either. 308 is SA and 06 is LA...you can deceide if that is a factor our not. Deer it just don't matter..spliting hairs.

Both good scopes but I don't regret switching to the Conquest one bit. I like it better then the VXIII's in features and optically it is better to my eyes. I have had mine now for 4 years and never had a shift in POI, that after hard miles and more then a few bumps along the way.Personally see no need to buy a 50mm objective for biggame hunting anymore...use to think bigger must be better but it just wasn't. I have 40 & 44mm, my hunting pard has a 50mm, I see no optical advantages between the 3.Personal preference I suppose, just didn't find a 50mm offered me anythingin regards tomy usage (1/2hour before to 1/2hour after- ourlegal hunting hours).
