Anyone shooting the 175eldx in their 280 or 280ai? Is your 280 throated for bullets this long or are you jamming them way down in the case? I have a few loaded to run over the chronograph. I am shooting them at the charge weight I settled for 185rdfs with 4000mr just to get an idea of velocity. The ones I loaded are with 4000mr but I will be working up with h4831sc or/and 7977 also. I guess I have rl26 also I could try. Mine is throated pretty well for 162s, not so much for really long 7mm bullets but I hate to mess with it because it shoots really well with basically everything I put in it. 139-185 so far, but I am sure I am giving up some velocity with the heavey bullets.
