To the OP.
Since your T3 is stock with no upgrades, you can do some upgrades to it that will allow it to run long VLD type loads that you would not otherwise be able to do in its stock form.
Modify your bolt stop, and swap out a medium (.308) magazine for a long (.300wm/30-06) magazine, and you will be ready to rock.
This is also a pretty good way to carry heavy for caliber projectiles like 200 grain Nosler partitions in big bear country if you ever felt the need.
Your T3 .308 is a very versatile shooting machine. BTW 500 rounds on it is no big deal.
This one, an early 2000s T3 .308 varmint has far more than that through it, and is still stacks bullets:
