I do not shoot our 17 inch alot on paper but I would think with really good ammo, shooters skills, rested, good optics and good weather conditions it is possible. Many get around 1/2 inch at 50 yards..Whether that translates to 1 inch at 100 yard range is the question. Likely could, dependent on the requirements stated above.
I know the two Taccoms we have are very nice shooting barrels. Even the 9 inch we just received a couple weeks ago shoots very accurate..
Like I say we do not shoot paper alot. But the Taccoms hit just about any little thing we shoot at. I can pick off small rocks and such with ease with the 17". I use CCI SV mostly. Pretty good ammo short of match grade.
Someone will be along I am sure that does more of that kind of thing.. I just know I like the Taccom ULW barrels alot.
