I have a .308 in Gen 2 and haven’t used it much, but no issues so far.
Have a Gen 1 and Predator in .308 and no issue in the Gen 1 but did have some feeding issues with the Predator after a while. The bullets just get “stuck” in the mag. A good “bump” will push them up, but it’s not something you want to be doing while getting on a second target.
I’m in the process of moving everything off the Predator to a new Go Wild .243. I’ll let y’all know if it ever gives me issues.
