I have had three 223 Ackleys. Two went to guys who are amazed with the velocity, a tad under 4000 fps with 40 gr Ballistic Tips, and the accuracy, half to five-eighths inch all day long, every day.
The one I have now is a rechambered Stevens 200 and is the most accurate of them all. Other than adjusting the trigger, the thing is just as it came from the factory, It isn't even bedded yet.
I painted the stock wintergreen camo and don't have to worry about it getting beat up on the snowmobile or in the brush.
At the price of the Stevens you could do one of each, decide which one you like best and have twenty guys on this board lined up to buy the other one when you post it on the Exchange Forum.
