RE: 270 wsm
I have a browning in the 270 wsm and I put a sims recoil pad on it,works for me.I shot 60 rounds in it one day with no problem.Looked at the T-3 and it was very similar to the browning stalker that I have but don't know the weight difference.So if you can find a sims pad to fit the t-3 it should work.
