With the 75’s I’ve used IMR 4895 but prefer 8208. They are my normal fodder out of my 24” barrel I can get them to 1000yds conditions need to be very favorable. They are very good even in windy conditions out to 750 or so out of that barrel.
I've been having good results using Tac and FGMM 205MAR primers, using just 23 seated at 2.260 for the 73 ELD and 22.5 grains. For the 75 OTM, seated at 2.250 using just 22.5 grains.
Honestly, both have not been able to beat my 77 SMK mod 0 or mod 1 clones but do well enough to kit steel.
I was able to get back out to the range today, not ideal weather, was cold with a little cross wind. I shot 2 groups and then ran 10 rounds over a chrono. The groups weren't great, but if you pulled out the flyer in the 2nd group, I would have been close to 3/4". I was cold & shivering a bit. I do think this load has some promise, and when the weather improves I'll get out and shoot some more. Once again, this is the 73gr eld-m over 22.8 gr of 8208 xbr in LC brass. Avg fps was 2594 (18 in barrel). The 23.8 was max load from Hornady's 5.56 data, but I do think there is room there to take the velocity a little higher. I'm not seeing any significant pressure signs at 22.8.
