I thought I'd get instant feed back on this forum
Anyway I emailed sportsmans WH and this is the responce I got.
Addressing your email, the T3 vs. the T3 super lite, is that the SL has a fluted barrel. Weights are as follows T3 SS are 6.34lbs. and the T3 SS SL are 5.94-6.12lbs, this includes the rings that come with all the Tikka's. Calibers are as follows: T3,243,270,308,30.06,300win,7mm,270wsm,300wsm.
T3 SL 223,22-250,308,30.06,7mm,300win mag. The Super Lite models are an exclusive line of products to Sportsman's Warehouse. We currently have these models in stock and pricing are as follows: T3 SS are $619.99 and T3 SS SL are $699.99. I hope this helps you out in your decision of which Tikka to purchase at Sportsman's Warehouse.
I was hoping I could get the Tikka SS SL in 270wsm but I guess not.
