1. is that out of a 26" stock chamber?
2. How far off lands are you if its not stock
3. today I tryed 95 retoumbo .030 off lands/fps about same as 93.5/didnt shoot as good 1.5 200YDs must be close to my max
4. need to invest In a better crono/maybe new shooter?

Factory rifle, only change is Pachmayr Decelerator recoil pad. I load to just clear the magazine length, 3.638". This same charge weight with the 250 gr PT gave me a MV of 3024 fps.
