Hornady ELD-x 145g - powders for 270 ?

[Cooperman]

Happy Christmas all,

ive managed to get hold of some of the above (from a very kind range shop in the North), but my normal 270 Viht powder 160  looks slow at max in the book with 560 offering slightly more. I've previously used game king 130's, but thought I'd try something new.

i was wondering if anyone had used these bullets and what powders in the 270 and what results? I'll load and try the 160 first and see how the pressures go, but there won't be much point in the additional bc benefit  if I lose 200fps from the 3050. 

Thanks all,

Matt
