LOL, but the OP wants to stay with .270 Win. My .270 AI 30" propels the 175 Matrix VLD at 2993 FPS with H4831SC. Others are claiming ~100 FPS with RL-26. At the time of my load development in 2012, people are using G1 = .650. (the original claim was .7828). Some think it should be close to Berger 170s G1 = .662. Perhaps members here have tested the BC lately. I corresponded with Matrix's new owner, but they have not tested the 175s BC yet. I have a couple of 1-lbs RL-26 to try on my next load development.Consider this. My 6.5x06 24" Bbl, 1/8 twist. It drives the Nosler 140 AB ( BC .509 ) at 3075fps with no strain, using Rel 26. You can do the math on drop at various ranges.
Cheers!
