I had it on a 24" single shot 700. A 264 WM barrel that had a badly eroded throat. My cousin had the reamer so he ran it in.
Crowded really hard with H870 or 50BMG I could break 3250 if I recall correctly but not by much.
Needed a lot more barrel than 24 to realize any improvement over the 264 WM. And it didn't take long to finish off that barrel.
