If the rifle is accurate with light bullets, it's telling me that the mechanical accuracy is there, but the gun might be very picky. Back to the bench and work up some different loads.
You could use a properly constructed light bullet, but in my opinion, they underutilize the cartridge. Started out faster, the combination of lower BC and high speed drag (squared by velocity), plus lower SD work together to make an OK short range bullet, if a bit lower momentum. But the narrow (high) velocity range and fast loss of velocity work against performance at longer range.

I get get really tired of people parroting stuff they read on the Internet that is just plain friggin
WRONG. If you don't know what you are talking about don't post.
308
130 Grain TSX BT B.C. .340 S.D. .196 MV 3100 FPS, 300 yards 2252 FPS 500 1811 FPS
This MV can be attained with 6 IMR/Hodgdon powders and in fact with certain powders you can get to 3200 FPS according to Hodgdon load data, and my personal experience.
165 Grain TSX BT B.C. ..380 S.D. .248 MV 2839 FPS 300 yards 2133 FPS 500 1726 FPS
This a a max load, only doable with one IMR/Hodgdon powder listed load.
Even at 500 yards the 130 grain bullet has an 85 FPS advantage over the 165 grain bullet in the same TSX BT configuration. He is at no disadvantage whatsoever shooting 130 grain bullets to 500 yards. Not many guys are shooting Caribou farther out than that with a Mossberg hunting rifle.
