[QUOTE="entoptics, post: 2040607, member: 104268"] I've had good results with H1000 and a 175 ELD-X. ~65.5-66.5 grains gets me around 2900 fps ± 25 in Remington brass, Fed 215M primer, hair over SAAMI COAL, 0.020" off the lands. 26" X-Caliber barrel, 1:8 twist. I went higher, with no pressure signs, but groups reliably opened up around 2950 fps, and pressure started to show around 2975 fps. The 175 ELD-X might not be stabilized as much as you'd like in 1:9+ barrel. Hornady claims 1:8.5 as minimum, but JBM's stability calculator suggests they're OK at 1:9.5 (if you include plastic tip length, they come out right around 1.5 stability factor) [/QUOTE]
