Keep us posted. I’m interested in your results as I was also ogling the 175 ELDX. I have a 1:9 twist 280 AI and was discouraged by the twist recommendation as well. I’m running the 162’s at around 3K with great results but the higher BC is always attractive.
My .280AI loves the 162 AMAX. I haven't tried any of the ELD-X in it yet. I may give some of these 175's a run.
