Note: should be “ free bore” apologies!H1000 and 3240 fps ( max load data shows no signs of excess pressure, but my shoulder sure does!!!) These “ beasts” can RECOIL! Best I could get was 1.2 Moa using 200 gr Accubond’s. That “ wby “ freeborn” has it’s issues!! If you don’t mind a single shot rifle, perhaps one could improve the accuracy with Berger’s ?? I seated the accubonds just shy of magazine length.
