RL 17 gave me a decent velocity boost over H4350. So be wary swapping to that if you already are working a H4350 load. RL 16 is quite a bit better in terms of temp insensitive compared to 17....so far. I loaded and tested in the San Antonio heat and am shooting them now in Canada where its 30 degrees cooler and my POI/Velocities are spot on still. Winter time might be a different story but 30 degree swing is still decent showing. RL 17 loads are much different up here. H4350 are fairly similar to my 100 degree day testing as well.
