I just had my new A-Bolt to the range for the first time today. Mine's a .223 without the BOSS, naturally. The trigger adjusted to it's lightest setting breaks at exactly 4 lb. Two different factory loads both went into an average of 1 1/2" at 100m. It's the sporter weight barrel and seems to hold group size even when the barrel is hot. I expect it will get better with some tweaked handloads. I've only fired 80 rounds but I like it so far.
