So I tried out the ADI 2217 in the 270wsm today. 5 loads starting at 67.5 and increments up to 70.5. 140 grn Nosler BT.
The highest 2 shots in the 100 yard group are 70 & 70.5 gns. 70.5 grn velocity was 3135fps.
I was hoping for close to 3,200fps but am wondering if I should just call it a day at 70.5 grns or push on to the target velocity. There are no pressure signs and the ADI max 70grns. Federal brass.
