I have not been impressed enough with RL-17 in the 3-4 guns I've tried it in to get enthused about it & have discontinued any further work with it.

I also use RL-19 with the 140's & have been very happy with it.

But I killed a WT deer with a 120 last year & it performed perfectly, but since I am usually hunting mule deer & elk at the same time, I usually just carry the 140's in that case.
