Abit of help and advice is always welcome and thanks in advance. I'm shooting a Mathews DXT, 60lbs with 26" draw, and 26.5" arrows. According to the chart and my dealer I'm right on the line between 400 and 500 spined arrows. I have been shooting Eastons St Epics 400 @8.7gpi, Eastons 3D lightspeed 500 @6.5gpi, and recently Flatline 400 @7.4gpi. I will be using theses for my 3D league and for hunting in the fall. My hunting shots won't be longer than 30 yards. Now I really liked the lighter arrows as they were forgiving in judging yardage and flater. I was told by the dealer that if I was going to the lighter arrow there wouldn't be a lot of noticable loss of kinetic energy as the newer bows transfer energy well to the arrows. I was going to try using the Flatline Surgical 500 @6.5gpi with 85 grain tips, figured that would be as light as I would go and flat enough to poke thru branches. Would I be wrong trying this setup for hunting as well as 3D league? Any other advice?
Thanks. |
Nothing really pokes through branches. Any arrow that hits a branch is going to go waaaay off it's mark. Ask Buhog7979 how that works out.
You are usually better off to go with a stiffer spine when you are on the borderline. You can cheat your spine a little by altering the weight of your tip. If you want to stiffen up your arrow spine some, go with a lighter tip, if it needs to be a little weaker, use a heavier tip. Length also plays a role in how the arrow acts. I shoot lightspeeds for 3D, indoor target, and hunting. I'm shooting 340's with 100 grain heads though. Flatlines and lightspeeds are *virtually* the same arrow. I just did a little quick math, and depending on your arrow setup, you will be really close to a 300 grain arrow. Not bad for hunting, could be better, could be worse. But just be sure you are shooting at least 5 grains per pound. I had yours figured a little lighter than that, but I'm just guessing on your nock, fletching, and insert weights. |

Thanks for the reply. What I mean by poking thru branches is getting thru the holes, flatter arrow flight would help. That light set up puts me at 310 grains so its as close to 5 grain per inch as I need to be. I know its a good 3D set up but for hunting do you think I would lose the kinetic energy to blow thru white tail? Might be something I want to try just want someone with more experience to give me an opion.
ETA- The dealer also told me when on the border to error on the stiffer side but did say I could get away with it. If I did go light I would be using 85 grain Slick Tricks, arrow length is short as I could go so no cheating there. If I used 100 grain tip I'm figuring it would make arrow too heavy up front. |

Something else to take note.
IF you were using mechanical broadheads, and they are of a forward expanding style, the stiffer arrow will promote a more reliable expansion without the 'cam' action which 'Rage' touts as having an advantage with their rear deploying blades. I have been shooting the 85gr Grim Reapers (forward expanding style) with great success.(I watch the deer drop from the stand after the shot) There used to be a video on their site showing how they were shooting the Grim Reapers into steel drums and plywood on severe angles in order to demonstrate that their forward deploying blades stood up to the abuse. I haven't looked it up in a while, but it was out there a couple years ago. My post here is totally null and void if you're using fixed blades though. And, I THINK your Slick Trick are fixed blades. I thought I'd throw this out there for those using mechanicals. |

I have been asking around about correct spined arrows and have been told to error on the heavy side. What I did find was a program that helps select arrows and helps in that way. Seems I have better options than I thought. Getting the correct fit for my bow is what I'm looking to get. A flat shooting arrow would be nice but accuratecy is better. Thought I would share the program with everyone here.

| Lightspeeds are ok, I used them for 1 season of 3d, I shot 65lbs lightspeed 400s, I switch over to X ringer HV at 60LBS for the same speed and a big raise in 3d scores from the little extra line cutting ability, That little bit of extra width gave me about 12-20 points per shoot. I still use light speeds as a hunting arrow. Dont really need the extra kinetic energy of the heavy arrows as the arrows. I use Blazer micros for vanes further eliminating drag and effects of cross winds. |
