I would think it'd work, though I might favor H4831sc for that weight class. Check Hodgon's website for load data for the 7mm RSAUM, and see if they offer data for that weight class using H1000.
Thanks Yorker-1, I loaded up some with RL-17 to start with but haven't had a chance to shoot them. I am going to shoot a ladder with the RL-17 and maybe a few others and see which one gives me the best combination of speed and accuracy. I will add H4350 to the list.
