It's good stuff, I've shot quite a bit of it. It has been replaced by Mk316 because the M118LR was found to be heat sensitive.
I have used it up into the 90-deg temp ranges without issues. It compares equally to FGMM 175 on accuracy.
I have not used any of the BHA 175-gr loads, but I personally had poor results with both the 168 AMax, and 168-SMK loadings.
I shoot the M118LR in my Sako TRG's and GAP rifles.
