I normally wouldn't even start this thread, but something about 200 grain broadhead makes me giggle. The goal for my next arrow build was a high FOC (front of center). As it sounds, FOC is the percentage of weight on the front half of the arrow, this is important for a few reasons, but the main one of my focus is penetration and KE. Even with a low poundage bow, I should have no concerns on penetration out to the 60 yard range (we can have that discussion later), and shorter ranges, concerns of a shoulder shot should be a thing of the past. I have a relatively short draw length (and subsequently short arrows) so a high FOC is a little bit more work for me. Lighter arrows make easier work of this, but I wanted a relativdly heavy arrow. I opted to go with a Day Six micro diameter arrow at 10.4 gpi, cut to 28.5 from the throat of the nock to the tip of the arrow, finished off with a 100 grain stainless steel outsert. I tipped that off with a 200 grain grizzlystik massai single bevel broadhead. These are factory second broadheads that did not meet their specs due to weight (total of about $70 for 6 broadheads versus $90 for 3). 6 broadheads weighed anywhere from 198gr to 204 gr for an average weight of 201 grains accross the board. Not enough to matter in most instances and will be sorted in the quiver by weight. This set up will be about 634 grains once I buy lighted nocks for these arrows. Of course with micro diameter arrows, that meant I needed a new quiver since my G5 head loc wont hold them. Annnnnnnnd since I had alread purchased a new sight (spot hogg fast eddie) and release (fang 4 finger), this has shaped up to be a pretty expensive week. So blah blah blah, this arrow is gonna be crushing bone at a screaming 220fps lol.   |

You are talking my language here. Since I hunt with traditional bows I have to pay more attention to my arrow set up. I really like those broadheads. A two blade cut on contact head penetrates better than any other design. The single bevel edge will rotate as it cuts through a deer. If you use helical fletching make sure it spins the same direction as the head will cut. High FOC with skinny shafts and a 2 blade head is a deadly combination. Good luck with it.
I used 175 grain 2 blade broadheads on Easton Axis shafts this year. I also have a short draw length. I got a complete passthrough on my buck with that set up out of a longbow. My arrows weighed around 550 grains if I remember correctly. I don't know the speed of my bow but I'm sure its below 200 fps.

I do fletch my arrows with a right helical even with 100 grain broadheads. Helicals are just more accurate in my opinion. These are right bevel heads. I didnt get too in depth with figuring out why (maybe offside shoulder), but I hit high on my buck this year and no pass through with a 100grain mechanical, total arrow weight was 524 grains. No blood trail to speak of. Once was enough. |

I had a similar experience with a rage mechanical out of a crossbow. It hit right in the shoulder and did not penetrate. The arrow flopped and fell out when it ran off. With a crossbow I use muzzy broadheads. With trad bows its 2 blades every time. I like the shaft to be smaller than the head. The broadhead creates a hole and the shaft follows through it with little resistance.

I love the size of the holes that Rage leaves but the only good size buck I've shot the penetration left a little to be desired. Went in behind the shoulder and got stuck in the offside arm pit area. Granted there was some kind of old wound there but still expected more. When I run out of 100 grain heads I plan on switching to 125 grain to see if that helps. |

I did the math on these and im sitting at 22% FOC. I was shooting for 19% so Im happy.

I had no idea there was that much "science" to shooting arrows and bow hunting. Kind of making me have second thoughts about wanting to delve into archery.

Like most things it can be as simple or as complicated as you want to make it. You can kill a deer with a wood bow and a sharp rock on a piece of bamboo if you want. |

Yay heavy arrows!
I'm using Grizzlystik momentum TDT 250 spine shafts, Ethics archery stainless inserts with stainless sleeves and 200 grain Maasai single bevels. Total arrow weight is 805 grains with a 26% FOC. At 65# with a 31" draw I'm getting 220 FPS average, with an Elite Impulse 34. Same arrows out of the Elite E35 at 70# I'm averaging 210 FPS.

An unexpected bonus to these heavy FOC arrows. Theyre super forgiving and very easy to tune. Ive got these broadhead tuned already, im never this ahead of the game this early.

Glad to hear they are working out. I've decided I'm going to up my total arrow weight and FOC this year. Nothing too crazy, just north of 500 gr. I will probably stick to a slightly heavier arrow with inserts and larger BH.

Turns out these werent that easy to tune. That first arrow was, after that it went down hill. Tried nock tuning each arrow and things got wonky from there. My assumption is im under spined, I thought with how much weight was up front it wouldnt matter. Bad on me, I ordered some 125gr magnus 4 blade hornets. Should still have me around 18% FOC, ill revist the single bevel, though likely in 150gr, once I get these dialed in.

Also was going to ask you what min distance you would use them as I don't know when the shaft will stop flexing on its path. I have a Hoyt Heat Superslam at 91lbs and had to use the largest spine AL shaft arrow . I wouldn't shoot any deer under 15 yards as it didn't have any penetration power yet. Found that out the hard way. |

Found that out the hard way. I didnt notice anything that would make me suspect I had a minimum range. I shot a doe at 12yards, from a 14' stand and the arrow hit in the shoulder blade area, and basically bounced off breaking in half. Found both parts of the arrow where I shot her. 5" of arrow had blood and where it broke was hair and blood. We never found her as blood trail dried up fast. It didn't blow thru like the other kills did. So talked to the archery guy at Rod-n-Reel bait shop, anyone remember them, and he said the arrow didn't stabilize yet and that 15 yard would be the minimum Shooting distance i should shoot with that bow. |

I got my 125 gr heads today and recalculated my FOC. Sitting at 17%, which is still pretty good for my short arrows. Considering even with 200gr heads I wasnt planning on shooting a shoulder blader on purpose,these should still perform well.
I messaged Day Six about appropriate spine for 150 and 200gr and they confirmed I need to move up to the 300 spine and potentially shorten my arrow as well. I'm gonna trade my 200's off to a friend for his 150s that he shot last year. I'll stick with the 125s this season and start on the 150s bext year.

What spine were you using? |
