Thread: Hornady sub-x 175gr load data...

Tried the 9.0gr Trailboss - rewarded with 995fps speed. Settled on 9.4gr - that will be the one I think. Should settle in at around 1040fps - should go close to the 7" drop at 50m and sufficient headroom under the 1080fps at sea level/0degC speed of sound. Normally we are slightly higher temp, and that gives a bit of a safety factor (20degC is something like 1110fps).
