I have had a few 88s and in all the calibers they came in. The triggers are bad, but can be made better. Not much better, but better. As I recall the Browning BLR trigger wasn't any better on the one I had.
All of mine have been accurate that I have shot. When I say accurate I don't mean hit a fly accurate, I mean 1"-1.5" consistently with handloads. My .284 Win consistently put 5 120g Nosler BT into .5"-.75". Not just once. but several times. 140g TSX into an inch. Same with the .243 I had. The .358 I have is a custom barrel and it has never gone over 1.5". I never shot the .308s I had, but with its reputation as a cartridge for accuracy I would believe it would be fine too.
When asking for Mule Deer's advice on loading the .358 he cautioned to load a grain under his suggested load since they were made up in a bolt action. I would think if one stayed with factory level loads there wouldn't be a problem in the .308, but those with more experience may tell you different.
