Or, if you're just shooting M855, you could search barf.com and someone might already have posted the answer. Or, you could get to a good KD range like Gene said and let us know how the lollipop technique works for you.  |
Thanks jatx!
I don't know when the next time we're going to the range but I'll experiment and let you all know what I come up with.
FYI - We're using M855.
