Thread: 270Win or 270WSM on a T3 lite?

Hi all,
A friend of mine is planning on getting a Tikka T3 Lite for Hunting and wants some feedback on which 270 round to choose?
Expected range would be 200~400m.
Use is for Hunting.

Currently he uses a good old 100% trusty Remington 788 in 308win!

...also any advice on what scope would suit this round & rifle.
His old Remington has had a Burris 3-9x40 which again has been perfect its whole life, so was looking at them, such as the "Burris Veracity 2-10x42mm or 50mm version..."

His total budget is ~$2k. (Subject to his wife's permission).
Any advice welcome.
Many thanks Grant.
