Very little left to add here. For me, the 7mm x 180 grain x 3000 fps bullet hits the recoil sweet spot while yielding great ballistics.
Meaning it's about all I care to shoot (a lot) in a hunting weight rifle. The T3 may or may not be twisted right to optimize this.
However, for the range you mentioned, I would not go that big. .280 Rem is fine. Some have allegedly run the lowly 30-06 and .270 just fine a longer ranges ...
But the 7 RM should sizzle at 500.
