I had first tried 4831 and R22 but Velocity was very plain...even after switch to R-25 I was still unimpressed with 130's at 3050 fps
This was with a Shilen barrel 1-8"....it might of been slower. The cartridge should be able to Push 140's at 2950 or 3000 fps with 24" pipe.
This did not end offering me anything over my 270 win so I did not end up keeping that barrel....although it did shoot well and shot a Whitetail Buck with it.
If I go through this again Ill probably go the AI route.
