Question 300 Win Mag ????????

A friend decided to try loading some 180 gr Nosler Accubond for his 300 Win Mag. He loaded them with the same powder charge(70 gr IMR 4350), WW cases, primers and seating depth as the Sirrocco 180 gr he was currently using. At the range the Noslers shot a very tight group, actually smaller than the Sirrocco's did, BUT they were exactly 3.5" low(at 100 yrds) with the Accubonds. The bullets are both boattail design, but the Sirroccos are much more thinner tapered in design. Is there that big a velocity difference or is the difference in the bullet design the major reason for the BIG difference in how different the two bullets shoot. Please help me out, it has both of us scratcing our heads!
