I am wondering when you have a rifled Ackley Improved does the gunsmith have to take the barrel off the rifle? Or do they just put the reamer in with it attached?

Yes, the barrel will have to be removed.
If you are going to have this done, spend the extra money and have the action blue printed. This will square up the action to the barrel and will help with the accuracy. My M700 280 AI is a tack driver.
What action and caliber are you thinking of?

However, I bought both as is and didn't realize that they were intentionally headspaced to 0.004 difference for fireforming. Pretty inpressive difference for very little change in diamensions. Alot cheaper than going to a 223 WSSM or 240 wby for me.

These reasons minimize and sometimes completely eliminate the first signs of high pressure in alot of AI chambers, most of them show no signs at all till the primer falls out during loading.
