Why'd you switch back from Shwackers? I was thinking of using them this year..... did you have issues?
Actually I did, but only with the last 2 deer shot with them.... (Previously I killed numerous deer with the 100 grain Shwackers without an issue). However, the last 2 deer went further than usual leaving very little blood, surprisingly. Upon inspection, it appeared that both heads failed to open although they were brand new.....That was enough for me even though it may have been a rarity. Back to basics from now on with the Thunderhead 100s.
