Just my 2cents on the topic. I thought I didn't need FA on a .308 for the same reasons as above until I went hunting with it a few months back, and following saftey procedures unload before climbing into a tree stand. Got in place QUIETLY inserted mag and then thought- If I let this BCG go I'm gonna scare everything in a 10mi radius away. I slowly rode it forward and at that point wished I had FA to seat the round. I had no choice but to let it slam. If anyones got some methods for this issue without using FA I'd be happy to learn.
