Wondering because i have shot 3 does this year so far( yes i have been having a good start)but the problem is i have not got a pass threw yet and 2 outta the 3 should have been. I believe im getting more than enough speed and kinectic energy.
Just in case im shootin a mathews hyperlite 28 draw 62lbs fmjs 400 cut at 26 1/2 using 100 grain grim reapers mech. the only thing on string is peep and 4 monkeytails n d loop.
After the last shot I took the grim reaper home and tryed to cut a piece of paper but it didnt cut at all. So imo i am thinking they were dull. Thats why i did not get a pass threw. Anybody please help. Thanks ahead of time

Am I reading this right, you have shot three does with the same broadhead without resharpening it? If so, that is quite a testament to the broadhead. I would never reuse a broadhead without resharpening it first. I run them over a hone or strop after one shot into a target.

no it was three seperate grim reapers. But i either bought them at the end of 2 seasons ago or the beginning of last season. I did not check if they were sharp before shooting them.

I think you should replace the blades or resharpen after every shot, either on game or a target. If it's not scary sharp I wouldn't hunt with it.

If you are expecting to get a pass through on most shots you should probably go to a different broadhead. When I was shooting an expandable I only got one pass through. went coc and now it is the standard.

My apologies to you, I stand corrected. I will leave others with more experience on mechanicals to answer your question.

I went out and bout a new pack already but just wanted to be sure thats what it was.So with my set up i should have more than enough speed n KE right

Re-sharpen the blades, makes sure you replace anything that is bent, and make sure that the opening mechanism is free of debris that will hinder it's function. I use Fixed BH's that I re-edge each time I shoot an animal with them, and I've put the same BH through 6 animals before losing it on that 6th animal. I have another that has been through 4 animals and is ready to work again this season. But regardless of what BH you're shooting, check the sharpness of the blades, and re-edge/sharpen them after each animal and before hunting if you practice with them.

You have to give your arrow weight and speed for someone to tell you, but I'm guessing you're on the light side. Still, there are a lot of variables that determine if an arrow passes through or not. Though it's extremely important in regards to the wound channel, sharpness is a really small variable in regards to getting a pass through. I doubt that's your culprit.

ya, you have more than enough energy (on a good shot) for a pass threw. you owe it to the animal you hunt to make sure your your BH are scary sharp, not only for pass threws but a dull head tears the flesh rather than cutting it. when you tear the flesh it clots faster than a clean cut. just like it when you cut yourself shaving you bleed allot longer than when you scrape you knee.

Well if your arrow weighs 10 grains per inch then thats a 265 grain arrow and lets say your shooting that arrow at 285 fps (just guessing the speed got the same bow) It should be 47.81 Ft- lbs if I did the math right I might be wrong after all I just graduated High school this year the formula I found on google is KE = (mass x velocity2)/2 hope this helps
