I haven't tried the 139 because up until recently I couldn't find any, but the 145 LRX has been available and has been working great. 46gr BG gets me 2850 and low SD with a rem mag primer, slightly slower and higher SD with a standard primer.

I plan to start with 47gr BG with the 139 LRX, which gives 2900 fps with 139 interlocks.
