Accubond BC(actual) .338 225g
Working with a Browning Abolt 338 Win Mag. Have been working loads with 250Berger Elite Hunter, 225 Cutting Edge, and 225 grain Accubonds(recently added). Bergers and Cutting Edge shoot a few tight & then throw fliers 4-5" at 300yds. I'm going to leave those alone until winter as I have a Utah Beaver unit tag for Sept 14th. I have yet to figure out my problem with those bullets but it may be neck trimming?? Nut behind the trigger??
Anyway, recently added Accubonds since i have used them in factory loads with good luck at closer range. Loaded them at 68-69.5 grains touching the lands and they are tight at 68 grains, under .75MOA, opened up & then tightened up again at 69.5.
My question is, has anyone come up with a realistic BC for them? I will chronograph soon but my initial impression at 300 yds is that the BC is over estimated.
Thanks in advance for any help
