Just back from the range today after testing velocity for two loads I am trying to develop. The set up - Number 1, H4350, Hornady Brass, CCI 250 primers, Hornady 165 SST, out side neck turned, seated .020 off the lands. Number 2 is identical except I used RL 17. What is surprising is both loads shot well above the QL estimate. I do know all the tricks to make QL match your actual results. I needed velocity to adjust the burn rate to match the actual velocity. The surprising result is both loads were well above the QL estimate. With H4350, I got 2914 (estimate was 2744) and RL 17 was 2993 (Estimate was 2833). Both loads where 1-2 grains below max load according to the Hornady reloading manual. Both loads shot well with the edge going to H4350. Looks like I will be adjusting the burn rate for both powders down in QL. Then I can chase the accuracy node. I didn't notice any excessive pressure signs. The center target was H4350 and the top two where RL 17. What do you guys think?
