26 grs 800-X w 1 3/16ths oz # 6s or #7s is a very nice load in AA or STS or Nitr-27 Hulls, I personally load it in the RIO hull w/Windjammer wad I do this so when shooting buddy's I know it is my backup load. And the RIO Primer gets it lit.
I am a firm believer in RIO primes never had a miss fire yet 40,000+ shot.
I do not like the 700-X powder, I use PROMO much cheaper. and Prom looks like 700-X but Promo is slightly less pressures than RED DOT but Alliant says to load it the same weight as Red Dot.
I load a lot of Promo in the Top Gun Hulls as I have over 10,000 empties
and over 10,000 Rio Empties, And over 20,000 AA Super Hdp shells, I load them for ATA registered Hdcp Targets using the Orange WT-12 wad w/17grs 1 1/8th oz
@1200fps And for 1250fps use 24.5 grs 800-X, Windjammer @7600psi a soft shooting load.
