I crammed all the Retumbo I could get under a 150 gr bst and velocity was in the twenty eights . Don't recall how much RL 25 I started with . I only loaded three rounds or so and didn't get a group . Didn't chrono them .

Pop , you mind looking at your magic chart for a 270 cal 130 Barnes XXX with muzzle velocity of 3487 . I just re-zeroed at 250 yds this afternoon and I'm wondering what the drop is at 300 and 400 yards . I can't find the B.C. number for them and anyhow my Nosler chart is in even hundred yard increments .

Sorry for Hi-Jacking your thread but figged this might be faster than a PM.
