First you'll have to determine what OAL you are going to start with, which depends on your chamber and magazine.
The ELD can't be seated to AR mag length, same as for the previous 75 A Max. 2.390" is the min I believe.
Data for the 75 gr JLK VLD from Hodgdon will work. You basically can't get enough Varget in the case to go over pressure. At 25.0 gr you're pretty compressed as it is.
Thanks, have you tried those.the 73gr ELD has a AR 2.26" OAL friendly ogive
I've used the 75 BTHP and A Max. Both were excellent. Even factory Hornady Superformance 75 gr BTHP loads shot sub .75 MOA at 300 yds.
