That might work in some bolt guns, but it's a bit high for the AR-15.
If you load it out to a long COL, the 32.0gr might not be much over 51,800psi, but its a really long bullet as you know.
At 2.260 COL, 32.0gr under the 127gr LRX is likely pushing it 2 grains over max.
I would approach 30.0gr with caution in the AR-15 or COL-limited actions like the Howa Mini.
