Unless the pins and/or pointers can be individually adjusted (which I don't think is possible on any of the double pin models), I think you'll have to remove then reapply the tape. You could try moving the whole pin housing downward (remove and reposition the two screws that secure the housing...
"Arrow stability was measured experimentally by taking the positional x and y data measurements from each arrow shot and developing statistical groupings for each different arrow/vane combination." (from Vanes and Stability/Restoring Torque when Archery Hunting)
@Bill V do you plan to publish...
I personally don't see the need to spend extra money/effort reinforcing the front end of a standard diameter shaft. These shafts are inherently quite strong due to their (relatively) large size. An aluminum (or brass if needed to get to your desired total weight) insert is just fine. External...
I don't particularly enjoy the task of fletching, but being able to do it at home on my own schedule sure beats having to make a trip to a bow shop to get damaged vanes replaced. You can use the undamaged vanes as a guide to help get the replacement vane aligned/spaced properly.
I've shot both and they've both worked fine for me. Use whichever one fits your string better. The weight difference is irrelevant and shouldn't factor into your decision.
I would still recommend total arrow weight around 450-500 gr. How you would get there with a 260 spine 5mm Axis would be a little different from what I described above; more of the total weight will come from the shaft and less from the head/insert because 5mm Axis is a very dense (high gpi)...
Here's my "keep it simple" recipe for a hunting arrow at your specs: 300 spine standard diameter (6.5mm/.245") shaft with middle-of-the-road density (9-10 gpi). Cut it about 28" carbon-to-carbon, put 175 gr total on the front (could be 125 gr head + 50 gr insert or whatever other combo you like)...
I've used an 8-32 machine screw (with a nut to serve as a depth stop) to install 5mm HITs. You could do the same with a 4mm HIT but would need a 6-40 screw. Or you could use a Deep Six broadhead or field point as an installation tool, just be careful to keep adhesive off the head/point threads...
I've put an elk and several whitetail through their 1.5 hp #32 grinder over the last couple years. So far it has worked flawlessly and grinds faster than I can feed it.
GT's standard diameter carbon shafts (such as the Hunter XT) have a slightly larger ID than other manufacturers. GT lists an ID .246" and most others are .244-.245". I haven't tried to measure shaft ID's with a micrometer to confirm, but I have noticed significant differences in how tight/loose...
You're unlikely to get any GMU recommendations on this forum (especially not a day before the application deadline). My advice is to apply for a preference point now (put hunt code E-P-999-99-P as your first choice) then do some research about Colorado. Start by reading the big game brochure to...
I've shot a few animals with Cutthroats. All were recovered and blood trails were decent. IME blood trails are influenced much more by shot placement than by broadhead design. For two pass throughs at the same location/angle, the head that makes a larger cut will likely put more blood on the...
1 fps per 3 gr is a good rule of thumb to estimate change in speed vs. change in arrow weight. To get a little more mathy (and more accurate), multiply the known speed by the square root of the ratio of the arrow weights: 247.5 fps × SQRT(407 gr ÷ 432 gr) = 240.2 fps. Either of those arrow...
Weight distribution doesn't affect speed; speed is a function of total arrow weight. Front end vs. back end weight distribution does affect dynamic spine. Weight distribution amongst the components on the front end has a negligible effect on spine...an arrow with a 125 gr broadhead + 75 gr...
550 gr total arrow weight should get you close to your desired speed at 29" DL/80# DW. Below are a couple 5mm options that would work.
Easton 5mm Axis, 260 spine, 28" carbon-to-carbon length, 125 gr head + 75 gr HIT + 3 vanes at 7 gr/ea + 9 gr nock = 552 gr TAW
Black Eagle Renegade, 250...
Yep. Now I'm seriously considering what I could do with a 1988 fire truck. I'm thinking strip down the back end and turn it into an extra long flatbed. That much bed length and a 10.4L Cat diesel would be a hay hauling son of a gun.
You're overthinking it. If you're shooting 4 vanes with a 1.5 gr max variance per vane, you're talking 6 gr (at most) of variance in total arrow weight. ±6 gr isn't going to be noticeable in your shooting.
29"/50# isn't really much of a handicap. I would go with a 2-blade fixed head of modest cutting diameter. Magnus Stinger would be my pick for "best bang for your buck".
I know it's mostly a lost cause and the nocoiners posting here are unlikely to change their minds. But answering their objections is good mental exercise, and maybe these posts will spark some curiosity amongst those with a more open mind. This particular thread may be approaching the end of its...
