MMP blue sabots coming apart is common - even two petals sometimes. Should not affect your accuracy - which it doesn't. Supposedly that's been fixed with a little better polymer. I dunno. I can only base that one one single report! Need more reports I guess!

If the bore feels looser than the Omega, that'll keep you from grunting & shaking while seating many of the common sabot/bullets. That shouldn't translate into bad shot groups. It just means that most times - your Omega & Breakaway will prefer different bullets.
