I have been told by several people (one that works for AAC, answered the phone when I called), that 55gr ammunition from my 1/7 12.5" barrel is more likely to cause a baffle-strike than something 62gr and up. Is this the general consensus?

I've never had one, or even seen one, with multiple 10.5" 1in7" barrels from LMT or Noveske, or a BCM 11.5" 1in7". Using Gemtech M4-02 or a Surfire Mini, and M193 or even commercial .223 55gr FMJ, for thousands of rounds.
Now I've probably jinxed myself, and will have a baffle strike tomorrow....

I have close to 10k through my AAC M4 2000 and most of it was 55gr. and 62gr. No baffle strikes yet.

That sounds odd to me.
I'd really like rsilvers to comment on this.

I don't see how that would be true. 55 grain is fine for 1/7 twist.
