Just picked one up myself. Haven't had a chance to shoot it yet but the 1:10 twist and the fact I will run it with my can, makes the handiness of the 16.5 barrel a huge plus for me.
Re: Remington AAC-SD
I have one in a Mcmillian A4 with badger DBM. I too would have to say it's the cats pajamas. I have only used 175 SMK's. Shoots great for my needs.
Re: New for the Remington 700 - the Bolt Lift
Mine came in tonight, what a piece of work. Thank you for such a quality part! Fast shipping too, granted it only had to go about 20 miles, still fast. I will be ordering more.
