I' m confident at anything 20 yards and in. 20-25 yards I' m 95% confident and won' t take anything beyond 25 yards. But for me 0-20 yards covers maybe 90% of my shot opportunities anyways. I can' t always figure it out, but it seems to me that a large percentage of my shots are always about 10-15 yards out anyways, so I concentrate on practicing at 10, 15 and 20 yards. It' s wierd because most of my hunting opportunities always end up being at about 15 yards. Maybe they like how I smell or maybe it' s because I hunt in thick cover and shots over 20 yards aren' t available.

Bottom line, no more than 20 yards because I know my 20 and in shots will be decent hits.
