As stated, back off from RL22 data. I was able to get 3175-3200 fps with RL23 and a 140 NBT. Don’t quote me on this, it has been a couple of years ago, but I think I ran out of case capacity with RL23 before I ran into high pressure signs.
***EDIT***
To clarify, the above is in reference to a 280AI.
Wow! Glad you redacted that. I get 3200 with my AI’s. I thunk 3200 in a 280 Rem was “a bridge too far.”
