After shooting a hog of about 110 lbs est. with a 150 lb CB carved tip limbs dacron string. Used a snuffer 125 tri-blade BH GT II 18" weight of 360 gr. Had complete pass-though. So just how much weight is actually needed to do the job ? I have most of my arrows set-up like i am still shooting my old recurve stick Bows. My heavy weights are 585 gr then they come on down. Some one want to discuss this ? Maybe its time fer me to lighten up & get some speed out of my CB's.

I shoot a 424g arrow tipped with a 1 1/2" cut 125g NAP Spitfire. After the pass through my arrows are usually buried up to the fletching unless I hit a rock or root in the soil. Last season I buried one in a root. I unscrewed the arrow, cut out the root and and brought it home in an attempt to retrieve the broadhead. After I carefully chiseled it out of the wood I spin tested the broadhead and sure enough it was bent. After the pass through there was still enough Kinetic energy in the arrow that it bent the broadhead when it hit the root. I learned a couple of things from this: 1. I have plenty of Kinetic Energy. 2. Don't waste you time recovering the broadhead. Just unscrew the arrow and be happy you got your arrow back. ;D 3. I have plenty of Kinetic Energy In my case I would drop to a 100g broadhead to flatten my trajectory a little but I always seem to have a bunch of 125g broadheads on hand at the end of the season. Note to self: shoot more deer next season.  Bob |

Ghost Ghost, You comment got me wondering what my FOC is. I measured it a while ago but couldn't remember so I remeasured it today using 125g and 100g field points. With a 125g field point I am at 20.2% With a 100g field point I am at 17.8% There was no accuracy difference for me when I tested with 100g field points just a flatter trajectory. Bob |

I'm confused, are you trying to PREVENT passthrough? Sounds to me like you're not satisfied with dead and want deader. In any case, with my under 300 fps bow I'm shooting a 400 gr arrow (GT Lazer II, 110 g brass insert, Blazers and 100 gr Slick Trick mag); with the over 300 fps bows, same arrow but 125 gr slicks. Gives me 18 and 20% FOC respectively, great accuracy and terminal performance BUT I cant prevent passthroughs either.

No i am not trying to prevent a pass-through, I was pondering the arrow weight needed fer a pass-through. I have been shooting my arrows of 585 & 560 gr always got pass-through. So now i shot the hog with an arrow 200 gr lighter & still got pass-through. That got me thinking of going abit lighter n faster & the traj. may flaten out just abit,instead of rainbowing so much |

Hi guys - I don't shoot a crossbow, so forgive me if this is a silly question, but doesn't the tip have more to do with pass through shots than 100 grains of arrow mass? Most of the compounds I've had would put a 450 grain arrow at about 275 to 280 fps and the arrows went through everything I shot with them. (Other than the rocks on the other side of the animal...) I guess my question is why would there be a difference between a crossbow and a compound? Mass, tip, and speed => KE... I would think you guys would want the same as all the rest of us... What am I missing? Thanks, just curious !

I am not too good with math. I reckon the BH will play a big part of the pass-through. Now that being said & i use a 150 lb CB the arrows have the punking chunker Traj. cause it be slow. The hog i shot with 360 gr arrow had a Magnus Snuffer 125 gr BH which is a big BH size fer the CB & affects the accuracy. The BH had enuff K E fer pass through but only went couple inches into the rocky ground after.

Using 100 and 125 gr Slick Trick mags. The trajectory flattens quite a bit, at 365 fps initial velocity only 9" drop between 20 and 40 yards.l |

By today's standards, a heavy hunting arrow will weigh 8 to 10 grains per pound.
