RE: BROADHEAD PENATRATION
First welcome to the forums and congrats on your second deer. I do not like to here about lost deer though I know it happens. Do you sharpen your broadheads on a stone? Remember when you buy them, they only have a factory edge on them and all should be sharpened up before using.
I think the 125 grain broadhead will help you out. Other then that increase you draw wieght and see what happens. Good Luck
