Hi, I have two T3 Lites and also one varmint model, none of them stainless. The varmint model is clearly heavier, not too heavy but heavier. The stock has an extra part added on to it, better for shooting off bags. The stock also has a nice monte carlo kinda thing on the stock as well, does give consistent cheek weld. I cannot honestly say it is more accurate than the lite models, but it is certainly not less accurate. My varmint is 223 and the lites are 243 and 308. I love the 243 as a lite but I still regret not getting the 308 in varmint, no particular reason, I just think it would have been better to shoot the 308 with the little extras that the varmint brings to the table.
