i shoot the 3 blade 100 grain muzzy, and think im going to shoot the swhacker broad head this year, i seen a show the other day on the prusute channle that matched up other broadheads on three diffrent tests, one they shot threw a metal barrel, many of them lost there blades going threw, the 2nd test was they imbedded a deers shoulder into balstic gel some didnt make it threw the shoulder, the rage broke off a blade going threw the gel, but did however go threw the shoulder, the 3rd was they set up a plywood board at an agle of 60 deg's many just glanced off the board and broke blades, In no way am i promoting any broad head, i was just shocked at the results that they were ubtaining threw the tests,
