I have tried Reloder 17 in my 6.5x284. Here are the results.
26" Barrel
139 grain Lapua Scenar
Lapua Brass
Federal GM210M primer
48.0 grains
Avg velocity(AV): 2868
ES: 82.00
SD: 36.81
Group avg(GA): .979"
48.5 grains
AV:2923
ES:88.0
SD:36.55
GA:.987"
49.0 grains
AV:2939

SD:24.21
GA:.740"
49.5 grains
AV:2977
ES:139
SD:58.76
GA:1.978" (hurl)
50.0 grains
AV:2997
ES:76.0
SD:30.22
GA:.603"
General observations:
Although faster than H4831SC, the 17 is not nearly as accurate and has a much higher ES across the board. I also noted that the 17 provides much more blast and recoil, as well as heats the barrel up VERY quickly. I cant help but think it will burn the throat out quicker than H4831SC.
Hope that helps.
