I had a 300prc built, and factory Hornady ammo (225 ELD) shoots sub moa at 100 yds. I'm hoping to reload something that's as good or better. I've seen reloading data elsewhere, but wanted to know if anyone here has had good results.
 
RL26 is your friend. This info and more is also in the ELR section post on the 300 PRC. There's another gentlemen there that also found a bit of a sweet spot between 74 and 75gr of RL26 I believe.

all 5-shot groups, 31", 9.5-9 gain twist barrel, virgin Hornady brass, CCI 250, 50 rounds on the barrel so far. Chrono is optical style, 20-25ft in front of the muzzle, so I suspect speeds are actually a touch faster.
