I cleared the barrel channel on my 270 Win FN Deluxe, the barrel had been bedded all the way to the stock tip. I was not certain the rear lug was ever touching, but now it is.
After rebedding I took the thing to the range and accuracy is improved but it is a 2 MOA rifle now. I may change scopes and see if that improves anything, and I may add more clearance in the barrel channel.
I was disappointed with the velocities I got with my 130 Noslers’ and 55.0 grs H4350. I wanted 3000 fps and I did not get it. This lot of H4350 takes one more grain in the 30-06 to have the same velocities as IMR/AA4350. So maybe I could add a bit more. The only ammunition I got 3000 fps was Federal factory. My rifle shot best with the 150’s, and that velocity is disappointing. I get better velocities with 150’s in a 308 Win.
I am going to try 130 gr Federal Fusion bullets, AA4350 and AA2700.
