Hi I shoot a 300 wby and I don't reload. I shoot nosler custom ammo in 180 gr accubond but I can't find them anywhere I found them in 200 gr accubond. I don't shoot much over 300 yards the norm being 150-200 yards. Can some one tell me if they are close to shooting the same or does the 200 drop a lot more I can't seem to find the balistic chart on the 2 of them any help would be awesome thanks in advance
