I wouldn’t be surprised to hear Hammers shoot tighter than Partitions.
Occasionally a Partition will be the most accurate bullet. You never know; it’s trial and error.
My HS Precision .240 Wby shoots the 100 NPT sub MOA, best was 1.7” at 400 yds. HS makes in-house barrels that shoot with the best, cut rifling like Brux and Krieger.
But overall, I’d bet on Hammer.
