To be absolutely honest i do not have the answer. I do not have a boggie target that i am aware of (and i don't want one
) so i don't think i missed anything specific it just seemed to take a few lines to get used to seeing them earlier than your used to therefore effected timing a little. I would guess that i shot too quick without pushing through the target due to seeing it so much sooner, but that's an educated guess as i got used within 2 lines so luckily didn't have time to analyse it. Again its an educated guess that maybe its similar for you maybe you need to let the target out a milli second longer to ensure full target lock then attack it.
Terms and conditions -
Obviously this is speculation as i haven't seen you shoot.
