For the 145 LRX Barnes says 55.0 max of IMR4350 is 3034fps, but in the low 40s my 24" Broughton was shooting about 2920fps (and around 2970 in warmer temps) at 55.5gr. With that .5gr over max I was getting .3-.4" on average.
145 LRX and 62.0gr RL26 I was, in the same low 40s, getting around 3120fps and about .5"
Next time at the range going to try the 150LRAB with 60.0-61.5gr and see how those do.
