Is the Accubond bonded all the way to the tip? I thought I read somewhere it was not.
As a note; in my experience (testing only, have not shot anything with an AB), they are relatively soft and fold back resulting in a narrow front. They end up with ~60% of their original weight. Probably use ABs next season for all my hunting.
Based on the ones I've recovered, wouldn't say their front is exactly narrow. IMO, the diameter they expand to is exactly the reason I've recovered them.
