But I tried them last year (Griz trick) and with the light poundage that I shoot (53#) I didn't get a pass thru (did not hit shoulder) at 23 yds.
What did you expect shooting a 53 pound bow with a 4 blade broadhead that has 2.5" of total cutting surface?
I attribute the lack of a pass thru to the 'flatter' design of the blades which produce more of a chopping rather than slicing action.
I attribute it to you choosing to shoot a big arsed broadhead out of a light poundage bow.
I switched back to my Magnus Stingers and get pass thrus every time with plenty of blood. And the last 5 buck shot with the stingers also died within sight.
Had you chosen the razor trick or the standard (1") slick trick instead of the huge grizztrick you would have gotten the same results.
