280: Alliant has data for RL25 in the 7 Rem Mag; I have it somewhere at home.I posted results in another thread, but in one 7 mag, 68 gr gives a bit under 3100 with the 160 partition, and 69 gr gave 3150. I know the data shows 70 gr as max with some 160 gr bullets.




The 280 Remington is overbore.
