They don't just shoot, they penetrate. Not as large a hole as some people like, but if you put it in the right spot you generally won't have to trail it far. I got 7 5/8" penetration into the dirt last year, after a pass-through on my deer with a 2 blade Ribtek. Nicked a rib going in and coming out, deer went maybe 30 yds. before he surrendered.
